helpers\BaseArrayHelper isIn()

isIn() public static method (available since version 2.0.7)

Check whether an array or Traversable contains an element.

This method does the same as the PHP function in_array() but additionally works for objects that implement the Traversable interface.

See also http://php.net/manual/en/function.in-array.php.

public static boolean isIn ( $needle, $haystack, $strict = false )
$needle	mixed	The value to look for.
$haystack	array\|Traversable	The set of values to search.
$strict	boolean	Whether to enable strict (`===`) comparison.
return	boolean	`true` if `$needle` was found in `$haystack`, `false` otherwise.
throws	yii\base\InvalidParamException	if `$haystack` is neither traversable nor an array.
