best way todo a case insensitive str_replace

[pmpa]

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.

I would encourage you to use eregi_replace function that uses regular
expressions.

$text = eregi_replace("([gr])", "<b>\\1</b>", $text);

You could use a regular expression...

preg_replace ( "/needle/i", "replace", $haystack );
------------------------^

The 'i' makes it case insensitive.
