Searching an array for a string pattern and store it in a variable

Question

Array
(
    [0] => LAMPION
    [1] => BANBU
    [2] => DT-T300-FNS
    [3] => T65
    [4] => DT-299-FNS
    [5] => T30

Yes.

$matches = preg_grep('/^.{2}-.{3}-.{3}\z/', $array);

If you want the first, just add [0] (you'll need a temporary variable first for < PHP 5.4).

what if ill remove all value that matches to $matches from the mother array?

@EllandJunsayPansensoy you want to remove the found entries from the original array? array_diff() could do that for you I think.

@EllandJunsayPansensoy If you want to remove all members which don't match, just assign this return value to your original array. If you want the inverse, do the same but use the PREG_GREP_INVERT flag.
