    To create a random string of x characters using defined string of possible characters we will first of all define a function which will return a random string of length that you have passed as a parameter to the function. The script is given below:

    <?php
function randomStr($len) { 
   srand(date("s")); 
   $possible="ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz1234567890!@#$%^&*()"; 
   $str=""; 
   while(strlen($str)<$len) { 
      $str.=substr($possible,(rand()%(strlen($possible))),1); 
   } 
   return($str); 
} 

echo randomStr(8); //calling the function which will generate a random string of 8 characters.
?>
