(PHP 5 CVS only)strripos -- Find position of last occurrence of a case-insensitive string in a string
Descriptionint strripos ( string haystack, string needle)
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.
This function may return Boolean FALSE, but may also return a non-Boolean value which evaluates to FALSE, such as 0 or "". Please read the section on Booleans for more information. Use the === operator for testing the return value of this function.
