Question

I have a web application I wrote in PHP. I use a single Class to handle almost everything this app does. I predefine a few things before the class such as database name. What I was hoping for is that I could set a define for mysql_error().

So when I run a SQL query and add die() of error, I want it to ouput “An Error Has Occurred!” if the app is running in a production environment, but then I can change the 1 define from define(“DIEOUTPUT”, “An Error Has Occurred!”) to define(“DIEOUTPUT”, mysql_error());

My die() function looks like: die(DIEOUTPUT);

Is this possible to do?

Answer 1

No, that is not possible.

Instead, you could create your own version of die():

function my_die(){
    if($is_production_environement) {
        die("An error has occured");
    }
    else{
        var_dump(mysql_error());
    }
}

Note:

• You should consider moving away from mysql_* functions to PDO or mysqli.
• Using die() (or my_die() for that matter) on a real webpage is not too userfriendly, consider alternatives
