Question

I have this code : 170-83746/2189

so to create a function, so that i can get the value before dash which is 170 and the value after dash which is 83746 and the value after slash which is 2189

I have read about regular expression in PHP but I couldn’t understand that thing

please help me

thanks for the solution, I come out with my own style using your help. Here is my code:

$number = "170-83746/2189";

function slice_trim($num, $symbol) {

  if($symbol=='/')
  $reg = '#/(\d+)#';
  else
  $reg = '#(\d+)-#';

  preg_match($reg, $num, $match);

  return str_replace($symbol,"",$match[0]);
}


echo slice_trim($number,"/");

Answer 1

if (preg_match('#(\d+)-(\d+)/(\d+)#', $number, $matches)) {
    echo $matches[1] . ', ' . $matches[2] . ', ' . $matches[3];
}
