In PHP, the strripos() function is used to find the position of the last occurrence of a substring (case-insensitive) within a string. It is similar to the strrpos() function, but it performs a case-insensitive search.This is the case-insensitive version of strrpos().
Example:
<?php $text = "This is a test string. This is another test."; $position = strripos($text, "TEST"); echo "Last Occurrence (Case-Insensitive) at position: $position"; ?>
Output:
Last Occurrence (Case-Insensitive) at position: 39
