Using preg_match on a multidimensional array to return key values arrays

Question

I have an array that is structured as such:

$data = array(
    \"abc\"=>array(
            \"label\" => \"abc\",
            \"value\" => \"def\",
          


        

Answer 1

preg_match_all returns the rows that match a pattern with a specific column name.

$pattern = "/REDUCTION/i";
$reductions = array_filter($data, function($a) use($pattern)  {
    return preg_match_all($pattern, $a['budget']);
});
