PHP mysql_query() or custom_funtion()

[peterjc]

Usually we would use

mysql_query($sql) or trigger_error(mysql_error());

 

So instead of using trigger_error() directly, could i use our own function like below?

mysql_query($sql) or showError();

function showError()
{
     trigger_error(mysql_error());
     die();
}

 

The purpose is i want to end the script if errors were  found.

 

Thanks in advance.

Yes, you can, but does not make sense b/s it will show you only one error -> mysql_error().

You have to use functions to show you multiple errors, for example mysqli_connect error number or something else..

mysql_query($sql) or showError(mysqli_connect_errno());

function showError($error = null)
{
    trigger_error($error); exit;
}

Thanks for that jazzman1.

 

By the way, i don't really know how the "or" statement work.

 

Example:

We usually use: mysql_query($sql) or trigger_error() and so on

 

could we actually use it for our own function as well? Example

 

own_function() or trigger_error();

 

Thanks

The custom function is quite unnecessary, especially if you take a second look at the PHP manual for trigger_error (): It's perfectly capable of halting further execution of the script on its own.
