I'm stumped using str_replace()

[Drummerbones117]

Alright im stumped on trying to figure this one out, maybe I shouldn't be using str_replace but it's the only thing I can think of right now.

I have a string of numbers seperated by commas like so "2,5,7,10,12,14," And I need to delete one of the numbers so I used str_replace and it works it's just that when I do it for the value 2 I end up deleting the 2 in the 12 also, anyone have any ideas?

Here's a sample of the code I have:
[code]
<?
$id = '2';
$bla = '2,7,10,11,12,';
$bla = str_replace($id.',', "", $bla);
echo $bla;
?>
///outputs 7,10,11,1
[/code]

Any help would be greatly appreciated, thanks.

how about this ghetto code:
[code]
$id = '12';
$bla = '2,7,10,11,12';
echo $bla."<br>";
$blabla = explode(',', $bla);
foreach($blabla as $key => $val) {
   if($val == $id) {
      unset($blabla[$key]);
   }
}
$bla = implode(',',$blabla);
echo $bla;
[/code]

This can be accomplished with:

$bla = str_replace(",$id," ",", $bla)

This would obviously force you to have commas at the beginning and end of the string.

Thanks Crayon Violent for the "ghetto" code :-P works great. Should've thought to explode it first but sometimes I guess when you look at something so long you end up overthinking.

Poirot I would have done that it's just a mess if I try and explode it.

Well thanks guys.
