strripos

Description

Returns the numeric position of the last occurrence of needle in the haystack string. Unlike strrpos(), strripos() is case-insensitive. Also note that string positions start at 0, and not 1.

Note that the needle may be a string of one or more characters.

If needle is not found, FALSE is returned.

Example 1. A simple strripos() example <?php $haystack = 'ababcd'; $needle = 'aB'; $pos = strripos($haystack, $needle); if ($pos === false) { echo "Sorry, we did not find ($needle) in ($haystack)"; } else { echo "Congratulations!\n"; echo "We found the last ($needle) in ($haystack) at position ($pos)"; } /* Outputs: Congratulations! We found the last (aB) in (ababcd) at position (2) */ ?>
