PHP Features are
Performance : PHP script is executed much faster than those scripts which are written in other languages such as JSP and ASP. PHP uses its own memory, so the server workload and loading time is automatically reduced, which results in faster processing speed and better performance.
Open Source : PHP source code and software are freely available on the web. You can develop all the versions of PHP according to your requirement without paying any cost. All its components are free to download and use.
Familiarity with syntax : PHP has easily understandable syntax. Programmers are comfortable coding with it.
Embedded : PHP code can be easily embedded within HTML tags and script.
Platform Independent : PHP is available for WINDOWS, MAC, LINUX & UNIX operating system. A PHP application developed in one OS can be easily executed in other OS also.
Database Support : PHP supports all the leading databases such as MySQL, SQLite, ODBC, etc.
Error Reporting : PHP has predefined error reporting constants to generate an error notice or warning at runtime. E.g., E_ERROR, E_WARNING, E_STRICT, E_PARSE.
Loosely Typed Language : PHP allows us to use a variable without declaring its datatype. It will be taken automatically at the time of execution based on the type of data it contains on its value.
Web servers Support : PHP is compatible with almost all local servers used today like Apache, Netscape, Microsoft IIS, etc.
Security : PHP is a secure language to develop the website. It consists of multiple layers of security to prevent threads and malicious attacks.
Control : Different programming languages require long script or code, whereas PHP can do the same work in a few lines of code. It has maximum control over the websites like you can make changes easily whenever you want.
In static websites, content can't be changed after running the script. You can't change anything on the site. It is predefined.
In dynamic websites, content of script can be changed at the run time. Its content is regenerated every time a user visit or reload. Google, yahoo and every search engine is the example of dynamic website.
