Your shortcut character class in the regexp are wrong, the shortcut classes like a space need a backslash \s:

I don't know if that will make your code do anything useful but it at least corrects the mistake in the regex.

Sry about using perl code in the php code tag must of missed the <code> tag.

Anyway I know about escaping the metacharacters, and I did that, but dunno for what reason I copied it wrong, not sure. thx for pointing that out though :P

One more question :
Afaik in a sub $_[0],$_[1] refers to the first and second parameter which was sent to the function (correct me if im wrong please). So for example I have

Code:

#!C:\Perl64\bin\perl.exe -w
print "Content-Type: Text-plain\n\n";

@horse = ("mdamdamad" , "asdasda" ,"asdasd" ,"a");

getindex ("asd",@horse);

sub getindex {
$string = $_[0];
@a = $_[1];
print $string."\n";
foreach $key (@a){
    print $key."\n";
}
}

the problem is that @a in getindex only gets the first value of @horse , and not the entire array. How do I manage to pass to it the whole array?
edit: i found out the answer I had to use @a= @_;
