strrposPodręcznik PHPPoprzedniNastępnystrrpos (PHP 3, PHP 4 )strrpos --  Find position of last occurrence of a char in a string Descriptionint 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. Notatka: 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.
