Match refers to in the array?
In_array ()?

$ A = 'abc123'; $ arr = Array (0 => 'abc123', 1 => '20180101', 2 => '20180101', 3 => '222aads2 ', 4 => '20140901', 8 => '20160901', 9 => 'asfds '); if (in_array ($ a, $ arr )) {echo 'matched successfully';} else {echo 'matched failed ';}

$ A = 'abc123'; $ arr = Array (0 => 'abc123', 1 => '20180101', 2 => '20180101', 3 => '222aads2 ', 4 => '20140901', 8 => '20160901', 9 => 'asfds '); if (in_array ($ a, $ arr )) {echo 'matched successfully';} else {echo 'matched failed ';}

It means you forget in_array. at half past one, you will not be able to remember it.
