Also, don't forget to escape the $ character in your expression, since it is
reserved for variable declaration.

Well ...
- the {7,9} means that the previous char/group should repeat 7 to 9 times
...
- ^ means the beginning of the string
- $ means the end of the string
So everything, that validates, is 7 to 9 numbers.
"123456789 This is a test" won't validate - it contains chars instead of $
(end of string

Although I'm not too familiar with regexp I'd say the code validates
because the icq number you are providing actually confimrs to the pattern.
The first seven to nine digits

Does it actually NEED a regexp?
UNTESTED code:
7) && (strlen($icq) < 9) ) {
echo "yah";
} else {
echo "nah";
}
?>
FWIW, Are you SURE that all valid ICQ #'s are between 7 and 9 chars?
Surely at some point they'll reach 10 chars, and *may* have started at 6?
