Question

I am working on my first ever .php application! All I am doing is posting some data to a database: simple stuff.

Right now, everything works fine, I can send my data to the DB no problems. However, I want to return an error message to my Objective-c application. I have the try and catch statements to make sure I connect to the DB, and if there is an error I would like to communicate that back to my application.

Here is some of what I have so far:

        $dsn='mysql:dbname=******;host=******;';
        $user='******';
        $pass='******';

        try {

        /* obtain a database connection handle */
        $pdo = new PDO($dsn, $user, $pass);

        } 
        catch (PDOException $exception) {
            echo("Failed to connect to the  database. Error: " . $exception->getMessage());
        }

Also, is it possible to set a limit for how long the PDO will attempt to connect to the database?

Right now when I purposely put in something invalid, it tries to connect for a long time.

If you’re trying to do what I think you are, it doesn’t work like that.

If you want to pass the error message to an Objective-C application, you will need to pipe, write contents to a file, or write the error to STDERR and capture it from the Objective-C application.

What exactly are you trying to accomplish? Calling a PHP script from an Objective-C script?
