PHP try/catch and fatal error

Question

I\'m using the following script to use a database using PHP:

try{
    $db = new PDO(\'mysql:host=\'.$host.\';port=\'.$port.\';dbname=\'.$db, $user, $pass, $o         


        

Answer 1

If database connection fails, $db from your first try .. catch block will be null. That's why later you cannot use a member of non-object, in your case $db->prepare(...). Before using this add

if ($db) {
    // other try catch statement
}

This will ensure that you have db instance to work with it.
