In previous tutorial we match at the beggining of the string given. But that is a case sensitive. If your condition like this: if(preg_match("/^ABC/", $string)) then the value of your string "abc". The script will returned with this message:

No match found

This is because of case sensitive. But in this script we will make the condition insensitive using regex "i" for insensitive. Shown below:

1. <?php
   
   // create a string
   
2. $string
   
   =
   
   'Ronard'
   
   ;
   
3. // try to match our pattern
   
4. if
   
   (
   
   preg_match
   
   (
   
   "/^ron/i"
   
   ,
   
   $string
   
   )
   
   )
   
   {
   
5. // echo this is it matches
   
6. echo
   
   'The string begins with Ron'
   
   ;
   
7. }
   
   else
   
   {
   
8. // if not match is found echo this line
   
9. echo
   
   'No match found'
   
   ;
   
   }
   
10. ?>
    

Even if your string given are ROn, rOn, RoN the script will read insensitive and display the message "The string begins with Ron".
