php split string based on pattern

Question

I have a string like this:

2234323,23,23,44,433;3,23,44,433;23,23,44,433;23,23,44,433;4534453,23,23,44,433;
3,23,44,433;23,23,44,433;23,23,44,433
7545455,23,23,4         


        

Answer 1

You can use preg_split for that:

$s = '2234323,23,23,44,433;3,23,44,433;23,23,44,433;23,23,44,433;4534453,23,23,44,433;3,23,44,433;23,23,44,433;23,23,44,433;7545455,23,23,44,433;3,23,44,433;23,23,44,433;23,23,44,433';
var_dump(preg_split('/(;\d{7},)/', $s, -1, PREG_SPLIT_DELIM_CAPTURE));

Your output will be

array(5) {
  [0] =>
  string(58) "2234323,23,23,44,433;3,23,44,433;23,23,44,433;23,23,44,433"
  [1] =>
  string(9) ";4534453,"
  [2] =>
  string(50) "23,23,44,433;3,23,44,433;23,23,44,433;23,23,44,433"
  [3] =>
  string(9) ";7545455,"
  [4] =>
  string(50) "23,23,44,433;3,23,44,433;23,23,44,433;23,23,44,433"
}

I think that the next thing (combine the 1st and 2nd and then 3rd and 4th elements) is not a big deal :)

Let me know if you still here problems here.
