 I'm used to the unless-statement in perl... How do I do this:

   if string A or B are NOT in string C, then do something and quit.

 In perl, I would do this:

 unless ($c =~ /$a|$b/) {
   blabla
   exit 0
 }

There is no 'unless' in PHP, so you just have to grind it out. If you are
searching for known strings, rather than string *patterns*, use the strstr()
function here: http://www.php.net/manual/en/function.strstr.php.

So, something like:

if(!strstr($c,$a)  !strstr($c,$b)) {
  bla;
  exit;
}

Completely untested ;) If you are looking for patterns, see preg_match(),
linked to from the link above.

True, but isn't unless just a negated while?


q.e.d.

while ($c==$a OR $c==$b) 
{
  blabla
  exit 0
}

Indeed, it is a negated something or other.

Doing stuff with || is always a good way to stuff up.  In the case of
your example it will always evaluate to true.

  if ($A != $C || $B != $C) {
  
  I think, but im fairly new

This would work if you did this:

If (!($A == $C || $B == $C)) {

   In perl, I would do this:
  
   unless ($c =~ /$a|$b/) {
 blabla
 exit 0
   }
