eregi_replace headache

[Anon]

Aurgh! Please help.

I have a variable $var which is contains either a word or phrase and a variable $paragraph which contains a paragraph. I want to substitute all the occurance or $var preceeded and followed by a space with a third variable $replace ignoring case.

I'm trying something like:

$paragraph = eregi("[[:space:]]$var[[:space:]]", $replace, $paragraph);

which isn't working. Better yet, I'd like to do the replacement if the $var is at the beginning or end of the $paragraph and if it is followed by a ., or :

So I thought I could do:

$paragraph = eregi("(^{|[[:space:]])$var([[:space:]]|.|\,|$",} $replace, $paragraph);

Which also doesn't work.

I've read and reread the php.net doc's on reg ex and all the reg commands. This should be easy. What am I doing wrong?

THanks in advance for anyone that can help!

you are just comparing uwing eregi()

to replace you need to use eregi_replace()

read the eregi_replace() at php.net now 🙂
