PHP (recursive acronym for PHP: Hypertext Pre-processor) is a widely-used open source general-purpose scripting language that is especially suited for web development and can be embedded into HTML.
PHP is one of the main languages used in dynamic web development. It’s one of the oldest language and a common component in the LAMP stack (Linux, Apache, MySQL, PHP). If you want to create a website or any back-end web service, PHP is one of the main languages you can choose from. If you need revisions to an existing application that runs on a Linux server, it’s common for the back-end coding to be done with PHP.
PHP developers are often simply called “back-end engineers.” A PHP developer is responsible for writing server-side web application logic. PHP developers usually develop back-end components, connect the application with the other (often third-party) web services, and support the front-end developers by integrating their work with the application.
They’re turn client’s specifications into a workable, tangible product that runs on a web server. Although PHP can run in a Windows environment, it’s more commonly used on Linux servers with Apache running as the web client. Many PHP developers package their applications this way with Linux and Apache to make it easier for the client to host it.
PHP developers code the functionality and brings an app to life. Collaborating with designers, they ensure that the front-end application is appealing to users. You may find that some PHP developers have front-end design skills, but often times, they work with UI and UX designers to create a user interface that’s engaging and supported by solid back-end functionality.
It is a PHP Developer's job to write, test and maintain the code for web pages and computer graphics programs. They use PHP, a widely used scripting language, to build websites, programs and applications that computers follow to perform functions. They are also responsible for writing, troubleshooting, testing and maintaining the source code for computer programs. If needed, PHP Developers also assist team members in problem solving.
A PHP developer should be able to visualize your application and what you need based on your conversations and documentation (if you have any). They should be able to understand your business so that they can provide you with an application that supports your goals and business logic.
PHP developers mainly create two types of applications: web apps with a database background, and APIs that provide your existing software and data to mobile apps and other developers. PHP code powers the back end of a web app, so a PHP developer will design and architect your code and the way it works to support the front end. APIs are often used when developers or apps need to query your internal data, and they allow you to provide this data to the outside world. For instance, your app might pull a list of tweets from Twitter’s API. A PHP developer will read the API documentation and implement it into your website. APIs are also used with some mobile apps to power the app’s data services.
Deliverables could be full source code files, or some developers help you upload the code to your web server of your choice choice. If you’re building a website from scratch, it’s vital that you choose a developer with the skills necessary to tackle a project from the ground up. A senior-level developer will know how to manage a project (they might assign a project manager), set expectations, estimate costs, and give you organized, scalable code that you can work with for years.
Just like other development areas, PHP developers have a variety of skill sets and levels. Senior-level PHP experts often have several other languages in their arsenal. They should be able to design a full application from the ground up. Junior-level developers have a few years of experience, but they often need to work with, or have their work reviewed by, a senior-level developer to ensure that code is efficient and properly written.
A developer can only do as good of a job as the specifications or information they get from the client. Communication is key so that your PHP developer fully understands your concepts and goals. When you post a project, you must be able to communicate key elements so that you can get the best estimates from the best developers.
Before you post a project request or talk to developers, you should sit down and map out your idea. This can be done using images, presentations, or other types of documentation. For instance, you can draw your own wireframes and then explain each concept in writing. Developers bidding on your project can get a better idea of what needs to be done and estimate far more accurately.
It can be difficult for a client to understand the duration of a project and its cost, but a developer can sit down and discuss project scope, a reasonable timeline, and any deliverables that you can expect during the project’s development process.
Once you know what you want from your end product, it’s time to write your project description. You need to be concise but provide enough detail to attract top developers. You can attach documents and provide video links to your project description to help developers better understand your goals.
Below is one sample of how a PHP project description may look. Keep in mind that many people use the term “job description,” but a full job description is only needed for employees. When engaging a freelancer as an independent contractor, you typically just need a statement of work, job post, or any other document that describes the work to be done.
Title: PHP Developer Needed to Build E-Commerce Website
Description: We need a PHP developer to build an e-commerce platform for our website. We have a rough wireframe document that explains the front end and the back end. We need help determining back-end architecture, so we want a developer to determine the way it will be built. We currently have hosting and need help uploading the code after it’s finished. The e-commerce store will host our product catalogue, take orders, allow customers to sign up, and then send email reminders to customers that left products in their shopping cart.
You can modify this description to better fit what you’re looking for, but it gives the basic requirements that a PHP development project might have.
PHP projects can take a long time, so expect a big project to take several months. PHP projects may require sit-downs to understand your requirements, design, coding, prototyping, and testing. All of these extend the deadline and can require several months for larger projects. A developer might even add a small percentage of time to the duration to ensure that deadlines are met. As with any project, the more descriptive your post is and the more you communicate with your programmer, the smoother the process will be.
Every satisfied customer on every website starts in the hands of a experienced web designer. This professional has the ability to capture the client’s vision, bring the design elements to life, and ultimately create a website that appeals to consumers. This is not easy task since it involves both creative and technical abilities, so a top web designer is experienced in many different disciplines.
Likewise, an in-demand website designer will also have insights into the business and marketing worlds to understand how a website can meet a client’s needs, convey their brand, and help embrace new customers online. This knowledge is used to maximize things like lead generation and overall engagement levels.
Web designers must always begin by considering a client’s website objectives and then move on to an Information Architecture (IA) to set a website’s information hierarchy and help guide the design process. Next, web designers can start creating wireframes and finally move to the design stage. Web designers may use several basic design principles to achieve an aesthetically pleasing layout which also offers excellent user experience.
Balance – It’s important for web designers to create a balanced layout. In web design we refer to heavy (large and dark colors) and light (small and lighter colors) elements. Using the correct proportion of each is critical to achieving a balanced website design.
Contrast– In color theory, contrasting colors are ones placed opposite one another on the color wheel (see also complementary colors). Web design offers a few other areas where contrast is applicable. Designers look at contrasting sizes, textures and shapes to define and draw attention to certain sections of the website.
Emphasis– We touched on this a bit when discussing contrast. Emphasis is a design principles founded in the intentional “highlighting” of certain important elements of the website layout. It’s important to note that if you emphasize everything on the page you end up emphasizing nothing. Imagine a page in a book where 80% of the content is highlighted in yellow…does anything really stand out? This is the time to take a look at that Information Architecture for direction.
Consistency – Also called repetition or rhythm, consistency is a critical web design principle. For example, clean and consistent navigation provides the best user experience for your website visitors.
Unity – Unity is the relationship between the various parts of the website layout and the composition as a whole. Based in the Gestalt theory, unity deals with how the human brain visually organizes information by grouping elements into categories.
Web developers, sometimes called programmers, take the design created and build a fully functioning website. To put it (very) simply, think of the design as a non-interactive “picture” of a website. Developers take that design and break it up into it’s components. They then either use just HTML or a more dynamic approach incorporating programming languages such as PHP to develop the various website pages. More advanced web developers may choose to utilize a Content Management System (CMS) like WordPress or Joomla in order to streamline development and allow clients an easy way to maintain and update their website.
Web developers may convert a static layout into a dynamic website by using image and content sliders, active states for links and buttons, and other interactive elements.
It pays to do a little bit of homework before hiring a web designer since it can have a drastic effect on the overall price and the quality received. For example, a simple website without any large customizations can be launched with a pre-made theme at a minimal cost. This may not be suitable for websites anticipating lots of custom layouts and/or extensive traffic, so it’s good to know up front what type of designer will be required or if you’ll also need a developer.
Take a look at an example web design project description. Keep in mind that many people use the term “job description,” but a full job description is only needed for employees. When attracting a freelancer as an independent contractor, you typically just need a requirement of work, job post, or any other document that describes the work to be done.

After posting a detailed, well-thought-out project description that defines what you’ll need from your web designer, it’s time to start analyzing proposals. How do you select the top talented designer for your project?
When it comes to finding the top talented web designer, start by reviewing for portfolio samples that match your requirement. Be sure to ask freelancers about their experience with other facets of design as well, and consider the overall goal for the website being built.
Finally, it’s important to verify that a web designer understands the brand in question and its overall goals online. A qualified professional will be able to give a list of any expected obstacles, plus estimate the amount of time the project will take and the total cost. Since complex website projects could require months to complete, a good working relationship is essential.
With the right freelance web designer, you can end up with a finished product that brings your vision to life. Just take the time to create a detailed project description, review each freelancer’s proposal and portfolio, and ask them a few web design interview questions to determine if they’re the right fit for the project.
Web scraping, web harvesting, or web data extraction is data scraping used for extracting data from websites. Web scraping software may access the World Wide Web directly using the Hypertext Transfer Protocol, or through a web browser. While web scraping can be done manually by a software user, the term typically refers to automated processes implemented using a bot or web crawler. It is a form of copying, in which specific data is gathered and copied from the web, typically into a central local database or spreadsheet, for later retrieval or analysis.
Web scraping a web page involves fetching it and extracting from it. Fetching is the downloading of a page (which a browser does when you view the page). Therefore, web crawling is a main component of web scraping, to fetch pages for later processing. Once fetched, then extraction can take place. The content of a page may be parsed, searched, reformatted, its data copied into a spreadsheet, and so on. Web scrapers typically take something out of a page, to make use of it for another purpose somewhere else. An example would be to find and copy names and phone numbers, or companies and their URLs, to a list (contact scraping).
Web scraping is used for content scraping, and as a component of applications used for web indexing, web mining and data mining, online price change monitoring and price comparison, product review scraping (to watch the competition), gathering real estate listings, weather data monitoring, website change detection, research, tracking online presence and reputation, web mashup and, web data integration.
Using data scraping you can build sitemaps that will navigate the site and extract the data. Using different type selectors you will navigate the site and extract multiple types of data - text, tables, images, links and more.
Web scraping is the process of automatically mining data or collecting information from the World Wide Web. It is a field with active developments sharing a common goal with the semantic web vision, an ambitious initiative that still requires breakthroughs in text processing, semantic understanding, artificial intelligence and human-computer interactions. Current web scraping solutions range from the ad-hoc, requiring human effort, to fully automated systems that are able to convert entire web sites into structured information, with limitations.
In order to remain competitive, businesses must be able to act quickly and assuredly in the markets. Web Scraping plays a big role in the development of various business organizations that use the services.
The benefits of these services are:
It’s important to note that not all scraper will be ideal fits for every project. For example, those with highly analytical backgrounds in software engineering would be ideal for developing algorithms but may not be the right fit for a data scraping project. That’s why it’s so important to understand what type of scraping expert will bring the most benefit to your company and business goals.
What is the overall learning you hope to find?
By including your goal in the project description, it allows professionals to better understand what type of work is required.
What core skills will scraping experts need to complete the project?
The answer will revolve around your current data infrastructure and the processes used to extract information.
Would you benefit from someone with highly specialized skills in a few areas of data scraping, or would a well-rounded expert serve you better?
Are there any time constraints to consider with this project?
Let professionals know the amount of hours of work that might be involved.
What kind of budget will this project have?
The more experience and expertise a data scraper has, the higher they expect to be compensated. Higher budgets will more likely give top-tier experts a reason to submit a proposal.
Below is a sample of how a project description may look. Keep in mind that many people use the term “job description,” but a full job description is only needed for employees. When engaging a freelancer as an independent contractor, you typically just need a statement of work, job post, or any other document that describes the work to be done.

Remember that technical ability is only a small portion of what makes an excellent web scraper. Great web scrapers are inquisitive—they want to ensure that they’re seeking the right types of answers, plus they’ll take an interest in your business to better understand it. The ideal professional will also be able to advise you on additional metrics to analyze and compare in order to help you meet your goals.
Also, keep in mind that communication is always a key consideration in the data science field. A brief interview can allow you to gauge how strong each professional is in expressing ideas and explaining their process. The more you speak to each professional by phone, email, or chat, the better you’ll be able to gauge their professionalism and communication skills and determine whether they’re right for your project.
