  • Simple: PHP is a very simple language because it contain all data in the form of data member and member function(simple variable and methods) and it is work on OOPs(Object Oriented Programming Concept)

in Php if code is wrong it will give error output and tell what is error.Many programmer find it familiar.

  • PHP performs system functions, i.e. from files on a system it can create, open, read, write, and close them.
  • PHP can handle forms, i.e. gather data from files, save data to a file, through email you can send data, return data to the user.
  • You add, delete, modify elements within your database through PHP.
  • Access cookies variables and set cookies.
  • Using PHP, you can restrict users to access some pages of your website.
  • It can encrypt data.
  • Security: Php provides developers and administrators with a flexible and efficient set of security safeguards.these safeguards can be divided into two frames of reference :system level and application level.

System-Level Security Safeguards:

  • Php can run in what is known as safe mode which can limits users attempt to exploit the php implementation in many important ways.
  • Limits can also be placed on maximum execution time and memory usage,which if not controlled can have adverse effects on the server performance.Much as a cgi-bin folder ,administrator can also place restrictions on the locations in which user can view and execute php scripts and use php scripts.

Application- Level Security safeguards:

  • Several trusted data encryption options are supported in php’s predefined function set.
  • Php is also compatible with many third party applications,allowing for easy integration with secure e-commerce technologies.
  • Another advantage is that PHP source code is not view able through the browser because the script is completely parsed before it is sent back to requesting uer.
