strrchr
(PHP 4, PHP 5, PHP 7, PHP 8)
strrchr — Find the last occurrence of a character in a string
Description
$haystack, string $needle): string|false
This function returns the portion of haystack which
starts at the last occurrence of needle and goes
until the end of haystack.
Parameters
-
haystack -
The string to search in
-
needle -
If
needlecontains more than one character, only the first is used. This behavior is different from that of strstr().Prior to PHP 8.0.0, if
needleis not a string, it is converted to an integer and applied as the ordinal value of a character. This behavior is deprecated as of PHP 7.3.0, and relying on it is highly discouraged. Depending on the intended behavior, theneedleshould either be explicitly cast to string, or an explicit call to chr() should be performed.
Return Values
This function returns the portion of string, or false if
needle is not found.
