note 15968 added to function.is-numeric

I changed function sent by "ealma@hotmail.com 18-May-2001 12:02" a little bit (it should be faster now). Here is some code that will detect large values for numeric and for PHP3. function is_num($s) { for ($i=0; $i<strlen($s); $i++) { if (($s[$i]<'0') or ($s[$i]>'9')) {return false;} } return true; } You can also check only the first char in string (($s[0])<'9')and($s[0]>'0')), since php converts string to numeric only from beginning to the last digit. -- http://www.php.net/manual/en/function.is-numeric.php http://master.php.net/manage/user-notes.php?action=edit+15968 http://master.php.net/manage/user-notes.php?action=delete+15968 http://master.php.net/manage/user-notes.php?action=reject+15968
