Prozeduraler Stil
<?php
$link = @mysqli_connect('localhost', 'fake_user', 'my_password', 'my_db');
if (!$link) {
die('Connect Error: ' . mysqli_connect_error());
}
?>
Die obigen Bespiele erzeugen folgende Ausgabe:
Connect Error: Access denied for user 'fake_user'@'localhost' (using password: YES)
The mysqli->connect_error property only works properly as of PHP versions 5.2.9 and 5.3.0. Use the mysqli_connect_error() function if compatibility with earlier PHP versions is required.
