STRISTR

Case-insensitive strstr()

SYNTAX

stristr ( string $haystack , mixed $needle [, bool $before_needle = FALSE ] ) : string

PARAMETERS

haystack

The string to search in

needle

If needle is 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, the needle should either be explicitly cast to string, or an explicit call to chr() should be performed.

before_needle

If TRUE, stristr() returns the part of the haystack before the first occurrence of the needle (excluding needle).

RETURN

Returns the matched substring. If needle is not found, returns FALSE.
