# strrpos

(PHP 3, PHP 4 )

strrpos -- Find position of last occurrence of a char in a string

## Description

int strrpos ( string haystack, char needle)

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. 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`.

> Note: 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:

>     // 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.
