PHP | parse_str() Function

The parse_str() function is a built-in function in PHP which parses a query string into variables. The string passed to this function for parsing is in the format of a query string passed via a URL.

Syntax :

parse_str($string, $array)

Parameters: This function accepts two parameters as shown in the above syntax out of which the first parameter must be supplied and the second one is optional. All of these parameters are described below:

  • $string: It specifies the string to parse.
  • $array: This is an optional parameter which specifies the name of an array to store the variables. This parameter indicates that the variables will be stored in an array.

Examples:

Input : "name=Richik&age=20"
Output :  $name = Richik
          $age = 20

Input : "roll_no=2&year=2nd&gpa=8.3"
Output : $roll_no = 2
         $year = 2nd
         $gpa = 8.3
