generates the dynamic page.).
o PHP stands for Hypertext Preprocessor.
o PHP is an interpreted language, i.e., there is no need for compilation.
o PHP is faster than other scripting languages, for example, ASP and JSP.
o PHP is a server-side scripting language, which is used to manage the dynamic
content of the website.

functions are NOT case-sensitive.
Error Reporting
❖ PHP have some predefined error reporting constants to generate a warning or
error notice.
Real-Time Access Monitoring
❖ PHP provides access logging by creating the summary of recent accesses for the

❖ Advantages and Disadvantages of PHP
❖ How to Install For Run PHP

• WAMP for Windows
• LAMP for Linux
• MAMP for Mac
• SAMP for Solaris
• FAMP for FreeBSD
• XAMPP (Cross, Apache, MySQL, PHP, Perl) for Cross Platform: It includes
