The one time I think I may need to use ereg*

[dmsuperman]

Alright, here's my question. I have a variable, let's say $blah. Let's pretend (though this isn't the case) that $blah is $_GET["somefing"];

Now, there's no way I can be sure that $blah will really be a correct RegExp pattern, and I don't want it to be. My question is, how could I do a case insensitive replace of something.

preg_replace("/stuff/i", "TEH NEW STUFF", $var);

How can I use anything in stuff's place, even stuff like periods without having to escape them? I don't want to use str_ireplace, it's PHP 5 only and I'm using 4.3.10.

Also, eregi_replace is no good because I want all characters of $blah to be parsed literally, not as regexp patterns.

$stuff = (get_magic_quotes_gpc()) ? stripslashes($_GET["somefing"]) : $_GET["somefing"];

$text = preg_replace("/" . preg_quote($stuff,"/") . "/i","ALALALALLAAL",$var);

Thanks a ton, will try this out now

It works, I didn't know about that preg_quote.


You learn something new everyday
I think there needs to be a "Name that function-inator" on the PHP site, I always know it's possible to do something but don't know the name of the function.
