I want to remove all items that match the dimension fo the furniture. is it possible to do that using one regex expression? really apreciate the help

Answer 1

You probably need something like this:

foreach ($array_of_arrays as &$some_array) {
  $some_array = array_filter($some_array, function($el) { 
    return ! preg_match('#^\d+x\d+#i', $el);
  });
}
unset($some_array);

In other words, you filter each of these arrays with the function that tries to match its elements, one by one, with pattern…

`/^\d+x\d+/i`

… which means ‘match the beginning of the string, then any number of digits, then x character, then any number of digits’. From what I’ve seen in your examples, this is a pattern to follow, as ^\d+x\d+x\d+ won’t match ’40X40′ value.
