str_replace (case insensitive)

[Anon]

I am looking for a way to implement a "stri_replace" function, that is, one that is case insensitive.

I've tried tokenizing the target string into an array with explode, and then lower casing each array element -- and then doing the replace with str_replace(). But it seems like a lot of work. And I can't get it to work regardless.

Anybody know a short cut here, or have an algorithm that works?

Thanks in advance.

Why don't you just use eregi_replace?

Thanks, I'll check it out. Will this work the same way that str_replace() works, only case insensitive?

The PHP manual cautions users that str_replace() should almost always be used instead of ereg_replace. I'm not sure why other than perhaps speed. It seems like needless function duplication in the library.

$var = eregi_replace("word","replacement",$var);

Dunno why str_replace exists, I use it for smilies and the eregi_replace for censorship.
Both seem to pretty slow, the script certainly is anyway.
