title: Incrementing a number with str_pad (PHP)
body: <p>I am creating an incrementing number starting with 1001. If the number goes 1001,1002,1003... when it reaches 10, will it be formatted like 1010 or will it be 10010? I need it to just go in order and be 1010 and when it reaches 100, 1100.</p>
  
  <pre><code>$prefix = "1"; // update the prefix here
  
      $number = 1;
      $number++;
      $unique = str_pad($number, 3, "0", STR_PAD_LEFT);
      $unique = $prefix . $unique;
  
  print_r($unique);
  </code></pre>
