Description:
------------
This is to do with Preg Split. When preg_split is used with the flag PREG_SPLIT_OFFSET_CAPTURE, it returns an array, with the matched string, followed by the offset. 

When the flag PREG_SPLIT_DELIM_CAPTURE is used, it first returns the matched string, and then returns the string.

I am not sure if the functionality of PREG_SPLIT_DELIM_CAPTURE should return as an array, it would be far more useful it did work this way. Is this a bug with my version? Or, is this indeed the way it should function?


Reproduce code:
---------------
$result="";
$operations=preg_split("/(&\d*=op)/",$ops);
   foreach($operations as $op) {
   $allOps[]=$op;
   }



Expected result:
----------------
each allOps will have an array of string and delim for each match found.

Actual result:
--------------
array(allOps[0]=>"some string",allOps[1]="delim")
