hello, this is my first post I think... it deals with the order of replacement, in the preg_replace() function, when you're replacing multiple values. Kind of hard to explain... but here is an example...

 
$count = 0;
$text = "in out in out";
$pattern = array('/in/e','/out/e');
$replacement = array('in()','out()');
$return = preg_replace($pattern,$replacement,$text);

function in(){
global $count;
$count++;
echo "IN: ".$count;
return "in: ".1;
}


function out(){
global $count;
$count--;
echo "OUT: ".$count;
return "out: ".0;
}

echo $return;

Ok, I made the code simpler, so you guys can see how it works... now this is the result...

IN: 1
IN: 2
OUT: 1
OUT: 0

in: 1
out: 0
in: 1
out: 0

Notice the $count, how it goes 1-2-1-0... thats because it searches $text for "in" first... than goes back and searches $text for "out"... It doesn't go line by line? Is there anyway (like a modifier) to make PREG searches for everything one time through? Instead of going one $pattern at a time?

My desired result would be:

IN: 1
OUT: 0
IN: 1
OUT: 0

in: 1
out: 0
in: 1
out: 0

Any input would be good. Let me know if you need me to explain more...

    Unfortunately this is how preg_replace works with arrays, it treats each element of the array as a completely seperate call. It's really just like doing

    for($i=0;$i<count($seach);$i++) {
  preg_replace($search[$i],$replace[$i],$subject);
}

    but without the overhead.

      Oh no thats what i was afraid of... HTH Bubble? What's that? Thanks for the quick reply...

      Oh no... so now i have to think about a work around... <-- puts on thinking cap.

        Hows about something like this?

        $count=0;
function inout($input) {
  global $count;
  switch($input[0]) {
    case 'in':
      $count++;
      echo('IN: '.$count);
      return 'in: 1';
      break;
    case 'out':
      $count--;
      echo('OUT: '.$count);
      return 'out: 0';
      break;
  }
}

$string='in out in out';
echo(preg_replace_callback('/in|out/','inout',$string));

        I haven't tested it so it'll probably need tweaking but the logic should be sound. Lut us know how you got on with it.

          hey..... that's a good idea... nice... yeh... yeh, that'll work

          that concept will work... thanks bubbles.

          Hopefully I can use it... because this one little part is just a little part in this thing i'm trying to script... It'll have to be a crazy Reg. Exp. Pattern, cause... much more complicated than In|Out... lol

          Good job, I didn't think of this.

            Oh gimme gimme gimme <drool> ... bubble like regex 😃

              That's ok... I think i'm going to attack this problem in a different way... Thanks anyways bubbles.
