Note: If you only want to determine if a particular needle occurs within haystack, use the faster and less memory intensive function strpos() instead.

Parameters

needle

If needle is not a string, it is converted to an integer and applied as the ordinal value of a character.

Return Values

Returns the portion of string, or FALSE if needle is not found.
