                                    strrpos

   (PHP 3, PHP 4 )
   strrpos --  Find position of last occurrence of a char in a string

Description

   int strrpos ( string haystack, string needle [, int offset])

   Returns the numeric position of the last occurrence of needle in the
   haystack string. Note that the needle in this case can only be a
   single character in PHP 4. If a string is passed as the needle, then
   only the first character of that string will be used.

   If needle is not found, returns FALSE.

   It is easy to mistake the return values for "character found at
   position 0" and "character not found". Here's how to detect the
   difference:

   <?php
   // in PHP 4.0b3 and newer:
   $pos = strrpos($mystring, "b");
   if ($pos === false) { // note: three equal signs
       // not found...
   }
   // in versions older than 4.0b3:
   $pos = strrpos($mystring, "b");
   if (is_string($pos) && !$pos) {
       // not found...
   }
   ?>

   If needle is not a string, it is converted to an integer and applied
   as the ordinal value of a character.

     Note: As of PHP 5.0.0 offset may be specified to begin searching an
     arbitrary number of characters into the string. Negative values
     will stop searching at an arbitrary point prior to the end of the
     string.

     Note: The needle may be a string of more than one character as of
     PHP 5.0.0.
