Stripping whitespace between commas?

[Boofo]

Does anyone know how I can make the following pre_replace also strips out whitespace BETWEEN the commas?

Right now it will trim the elements of any whitespace that may come before or after the comma. But, say, I have this:

2 4 , 3 , 1 1


It won't strip out the space between the 2 and the 4, or the 1 and the 1.

$str = trim(preg_replace('|\\s*(?:' . preg_quote($delimiter) . ')\\s*|', $delimiter, $str));

$tmparray = explode(",",$array);
array_map("trim",$tmparray);
$array = implode(",",$tmparray);
$str = str_replace(" \t\r\n","",$str);
pick one

(not tested)

I meant how to add that ability to the pre_replace line I posted, so it does that also. I know how to do it by itself.

Also, your second one doesn't work for spaces. This does:

$str = str_replace(" ","",$str);


Now, it there any way to get the preg_replace to do that also between the commas? Right now it only works on spaces before and after the commas themselves.

If you would like pretty much instant answer on this go ask it on stackoverflow. I use it all the time and I always get my problems solved within 15 to 20 minutes if not sooner. Just a suggestion.

I was hoping someone here might have an answer, too. ;)

I just asked on there so we will see what happens. Thanks for the tip.
