Example #1 $mysqli->connect_error example

Stile orientato agli oggetti

= @new mysqli('localhost''fake_user''my_password''my_db');

// Works as of PHP 5.2.9 and 5.3.0.
if ($mysqli->connect_error) {
'Connect Error: ' $mysqli->connect_error);

Stile procedurale

= @mysqli_connect('localhost''fake_user''my_password''my_db');

if (!
$link) {
'Connect Error: ' mysqli_connect_error());

I precedenti esempi visualizzeranno:

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.
