Removing numbers from a string

[gerkintrigg]

Hiya, could anyone tell me the best way to remove numbers from a text string please? I think it's using explode, but i don't remember the correct syntax and can't seem to find an example anywhere.

The string is coming from a database (dunno if this makes a difference).

thanks.

$string = "abc123abc";
$new_str = preg_replace("/[0-9]+/i","",$string);
echo $new_str;
