PHP : OVERVIEW
PHP (Hypertext Preprocessor) is a popular server-side scripting language used for web development. It was originally designed for creating dynamic web pages and has since evolved to become a general-purpose programming language. Here are some key aspects of PHP:
• Server-side scripting: PHP is a server-side scripting language, which means that it runs on the server before the page is sent to the user's browser. This allows for dynamic content and interaction with databases and other server-side processes.
• Open-source: PHP is an open-source language, which means that the source code is freely available and can be modified by anyone. This has helped to foster a large community of developers and users who contribute to the language and its development.
• Easy to learn: PHP is relatively easy to learn and has a low learning curve compared to some other languages. This makes it a popular choice for beginners and small to medium-sized projects.
• Integration with databases: PHP has strong integration with many database systems, including MySQL, Oracle, and PostgreSQL. This allows for dynamic content creation and interaction with databases on the server.
• Large community and resources: PHP has a large and active community of developers and users, which means that there are many resources available, such as libraries, frameworks, and forums.
• Cross-platform compatibility: PHP can run on various operating systems, including Windows, macOS, and Linux. This makes it a versatile language for web development.
• Support for web standards: PHP supports various web standards, including HTML, CSS, and JavaScript, which makes it a flexible and powerful language for web development.
Overall, PHP is a versatile and widely used language for web development, with a strong community and resources available to help developers create dynamic and interactive web applications.
PHP Eligibility Criteria
