Was wondering if anyone knows how to split a string into an array at the last occurrence of a repeating number and the number itself if it does not repeat.
ie.
$string = '1978497748773434793';
Needs to become array:
0=>197
1=>84977
2=>4877
3=>34347
4=>93

failed attempts:
explode('7'..
str_split('7'..

I have not tested this code but it should work

PHP Code:

$string = '1978497748773434793';
$x = 7;
$result = array();
$len = strlen($string);

for($pos1 = $pos2 = 0 ; $pos2 < $len; $pos2++) {
   if ($string{$pos2} == $x) {
      $pos2++;
      while($pos2 < $len && $string{$pos2} == $x) {
         $pos2++;
      }
      // $pos2 should now hold the position of the digit
      // after the last ocurance of $x in this segment
      $result[] = substr($string, $pos1, ($pos2-$pos1));
      $pos1 = $pos2;
   } elseif($pos2 == $len-1) {
      // last digit, add to array evan if it's not $x
      $result[] = substr($string, $pos1, $len-$pos1);
   }
} 


Ok, now it's tested, and it works

wow you rock. Thank you so much for taking the time to do that for me. I racked my brain for a while on that one.
