best way todo a case insensitive str_replace

["pmpa" <mail.pmpa@xxxxxxx>]

Hi all.

What is the best way to do a string insensitive replace?
Currently I am doing:

$replace = "g r";
$arr = explode(" ",$replace);
$text = "PHP is GreaT!";
for($i=0;i<count($arr);$i++){
$text =
str_replace(strtolower($arr[$i]),"<b>".strtolower($arr[$i])."</b>",$text);
$text =
str_replace(strtoupper($arr[$i]),"<b>".strtoupper($arr[$i])."</b>",$text);
}

Works except for "Ph","PhP","gr" etc...
I am looking for suggestions before using str_split(); because my $replace
string can be a bit large :)


Thanks in advance.

Pedro.
