PHP is being widely utilized in developing web applications and became one of the main languages for developers to make new applications. Leading social networking sites like Facebook and reputed organizations like Harvard University are both using PHP which makes PHP popular and increases its
credibility. However, over years, its area of use has shifted, and nowadays PHP coding language is ranked among the simplest and hottest programming tools for web development thanks to its many virtues which can be the main target of this text. It’s considered a really effective technology that gives a convenient development process with many additional tools to assist it. In fact, consistent with recognition of programming language Index (PYPL), PHP is the fifth hottest coding language
in the world. PHP is getting used widely in developing web-based and other applications across all domains. Few technologies whose development is supported by PHP are listed below : - Content Management System.
- Web-based applications and development of sites.
- E-commerce websites and applications.

- Processing of Images.
- Graphical interface design-based applications.
- Developing
the features of Flash.
