Returns the numeric position of the first occurrence of needle in the
haystack string.
public stripos ( object $haystack, string $needle, integer $offset ) : boolean | ||
$haystack | object | |
$needle | string | Note that the needle may be a string of one or more characters. If needle is not a string, it is converted to an integer and applied as the ordinal value of a character. |
$offset | integer | The optional offset parameter allows you to specify which character in haystack to start searching. The position returned is still relative to the beginning of haystack. |
Résultat | boolean | If needle is not found, stripos() will return boolean false. |
