Can I make str_replace not case senstive?

[Robo]

I'm doing a simple search function, and for the results, I want to make all the bits that has the string in it bold. eg:

$query = cash;
$result = Cashmere;

$result = str_replace ("$query", "<b>$query</b>", "$result");

echo $result; 

That would print "Cashmere" instead of "<b>Cash</b>mere" since it's different case, is there a way to get around that, or do I have to use the slower eregi_replace?

If case sensitivity is needed you would have to use eregi_replace unless you built your own custom function.

You could run a strtolower function on both parameters before doing the replacement.

you mean case INsensitive.

wouldn't that make the result lowercase? if so he probably doesn't want that.

Robo, i'd just use preg_replace() which is about 2x faster than eregi_replace().

$query = 'cash';
$result = 'Cashmere';

$query = preg_quote($query, '/'); // only needed if your 'query' has special reg exp chars in it

$result = preg_replace("/($query)/i", '<b>$1</b>', $result);

echo $result; 

in preg_replace() there you need PHP 4.0.4 or greater to use the $1 part. if your PHP is older than that, use \1. $1 is the preferred way though.
