In PHP 4, mysql_num_rows() and mysql_num_fields() will issue error messages if the argument is not a result set. In PHP 3 they didn't seem to do this. This may account for the new error messages after updating PHP. You can use the @ to 'suppress error messages' that may reveal delicate information to users such as paths to directories on your server. It can be preppended to almost any php function likely to result in an error, if used incorrectly.

Re: [PHP-DB] MySQL connection: Change on syntaxis?
Tomás García Ferrari pressed the little lettered thingies in this order... Hello, I updated php to version 4.0.5 and MySQL to version 2.32.39, had errors on lines like this: $rows = mysql_num_rows($result); and noticed that this is a solution: $rows = @mysql_num_rows($result); Is this a new use of the function mysql_num_rows? The only thing that the @ does is to supress errors. http://www.php.net/manual/en/language.operators.errorcontrol.php What's your code and the error(s) you're getting? mysql_num_rows still has identical syntax as it did in PHP3.

What are the error messages you get? The @ symbol suppresses warning messages being sent to the browser so it isn't fixing whatever the real problem is.

RE: [PHP-DB] MySQL connection: Change on syntaxis?
$rows = mysql_num_rows($result) should work. If you want to know what's going on, try doing: ?php $rows = mysql_num_rows($result) or die(Error grabbing number of rows.

Re: [PHP-DB] MySQL connection: Change on syntaxis?
Hi, the '@' is an error control operator avaialble in all php versions. When prepended to an expression in PHP, any error messages that might be generated by that expression will be ignored. Check the PHP Manual for more info.
