Question

Does anyone have a PHP function that for example if a mysql_error() happens due to well a MySQL error it will not output it?

By not output it I mean rather it not show the error on live site as I will use it with another function I have that would work a treat if I had a MySQL error function.

I am just finding it so annoying as I do it like this currently:

$q = mysql_query("SELECT * FROM something");

// if error occurs
if(!$q) {
   echo 'Error' . mysql_error();
} else {
  // else no errors so continue
}

On some of my webpages see I have several queries in a script and I would like to just be able to include the function at the bottom of all my PHP code and if a MySQL error occurs anywhere in my script for the function to catch the error instead of me doing multiples of the code I quoted above.

That way I can save myself a lot of unnecessary work and implement it with my email error function.

The most robust solution is to probably use trigger_error(). This way you can tie into PHP’s error handling system which is already prepared to deal with development and production environments.

$querySql = 'SELECT * FROM `foo`';
$queryResult = mysql_query($querySql);

if (!$queryResult) {
    trigger_error('Unable to execute query: ' . $querySql, E_USER_NOTICE);
}

Of course, the most convenience would be to make a decorating function for mysql_query() that automatically triggered the error. The DRY principle always applies.
