I don't understand what it is you're trying to accomplish, so, it's hard to
offer a solution. If you just want to verify whether or not a variable
contains numeric data, why not just use the is_numeric() function:
http://us4.php.net/manual/en/function.is-numeric.php
preg_match() will return TRUE if it finds the pattern ANYWHERE in the
string, so, that's why "asdf789" passes the test because it contains digits,
whereas 'asdf' won't pass the test because the numbers 0-9 can't be found
anywhere in that string.
If you want the entire string to be tested for digits, you need to add the
length of the string to the regex pattern:
$length = strlen($data);
preg_match("[0-9]{$length}", $data);
