Splitting a string before and after a character

regex string php split utf-8

[tomroberts]

Hi everyone,

I'm trying to split a unicode string before and after a particular character (or characters).

Basically, given a string like this:

trademark® some more text

I'd like to end up with an array like this, preserving whitespace:

Array
(
 [0] => trademark
 [1] => ®
 [2] => some more text
)

I was thinking I might be able to use preg_split, but I can't figure out how to write the regex (I can split after the character but not before) and I'm not sure if I can use a unicode character in an expression.

Apologies if this is blindly obvious, I've not had to use regular expressions much before.

Thanks in advance,
Tom

Hmm, both preg_split and explode remove what they split by. A custom function would work though:

[pre]function my_explode($delimiter, $input) {
  $pieces = explode($delimiter, $input);
  $count = count($pieces);
  $output = array();
  for($i = 0; $i < $count; $i++) {
    if($i !== 0) { $output[] = $delimiter; }
    $output[] = $pieces[$i];
  }
  return $output;
}[/pre]

That's great (and irritatingly simple), thanks Readie!
