PHP5 -> PHP4 -- replacing strripos

[minestrone]

Hi,

Ive been working on a page in PHP5 that uses the strripos function.

Ive now been told to move to PHP4 and obvioulsy strripos does not work under that. Is there a PHP4 function that i can use instead?

Or does anybody have any tips how to write a function to take in char and a string and return the last position of the char. Im not very good with string manipulation in PHP.

Thanks,

David.

originally got this from a comment in the php.net manual:

if (!function_exists("stripos")) {
  function stripos($str,$needle) {
   return strpos(strtolower($str),strtolower($needle));
  }
}

simple yet elegant way to add stripos(). and you can put in in your code and it will work on php4 and php5 servers both since it checks if it exists.

For your second question: Go here and look down the list of functions until you find strrpos, then click on it for usage details.
