Regular expression ?

[Josip Maslaæ]

Hello.

I'm stuck! :)

I need a regular expr. that would match any expresion that doesn't start
with some words (not letters - words!)

For example - reg. expr. that matches any expression that doesn't start with
words 'one' and 'two' ??

thanks !!

if (!preg_match("/^(one|two)/", $foo)) {
//do stuff
}

I would do it like this, then you can put the words in an array.
(extending Shawn's version a little bit)

$wordlist = array("one","tw o","three");
if(preg_match("/^(".join("|",$w ordlist).")/i", $foo)
{
// matched
}

Many thanks, but that is not really what I'm looking for.

Like I said, I need just a reg. expression(!) that does what I need - not a
work a round like this (solving it with !preg_match()).
My question was just a part of the problem I need to solve, so this solution
doesn't work for me.


What I need is something like negating the class but on strings:
for example:
'/^[^ot]/' - matches all expressions that doesn't start with o or t,
I need something like that but one whole string, not just letters.


thanks

You could use a negative lookahead:

/^(?!(one|two)\b )/
