matching everything but a word using ^ and preg_replace

[Daniel Koñczyk]

I can't fing a way, to match any characters except the phrase 'foo'.
Using [^abc]+ matches any character except a, b or c, but I need to not
match 'foo', because f is ok, o is ok, but foo - 3 letters at once not

Any clue?

Thanks

If you just want to match "some pattern when not followed by 'foo'" or
"some pattern when not preceded by 'foo'", then you're looking for
lookahead or lookbehind syntax. See the section on "Assertions" in <http://us4.php.net/manual/en/pcre.pattern.syntax.php>. For instance, here's two of their examples:

*foo(?!bar)

*****matches*any*occurrence*of*"foo"**that**is**no t**followed**by
*****"bar"
*(?<!foo)bar

*****does*find*an*occurrence*of*"bar"*that**is**no t**preceded**by
*****"foo"
