Question

I am trying to use foreach statment to run through a function that preg_replaces using regular expression. Can someone help, because my method doesn’t work..

$reg_sent is an array

function reg_sent($i){
  $reg_sent = "/[^A-Za-z0-9.,\n\r ]/";
  return preg_replace($reg_sent, '', $i);
}

foreach($reg_sent as $key=>$value){
  $value = reg_sent($value);
}

Answer 1

Check array_map.

$reg_sent = array_map("reg_sent", $reg_sent);

This will call reg_sent on every cell of the array, and return a new array with values modified. You can replace the foreach block you stated, with the above.
