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

I will not report what has already been written about testing if $db is empty. Just add that a "clean" solution is to artificially create an exception if the connection to the database failed:

if ($db == NULL) throw new Exception('Connection failed.');

Insert the previous line in the try - catch as follow:

try{

    // This line create an exception if $db is empty
    if ($db == NULL) throw new Exception('Connection failed.');


    $query = $db->prepare("INSERT INTO users (...) VALUES (...);");
    $query->execute(array(
        '...' => $...,
        '...' => $...
    ));
}
catch(Exception $e){
    $GLOBALS['errors'][] = $e;
}

Hope this will help others!
