Example #1 $mysqli->connect_error example
面向对象风格
<?php
$mysqli = @new mysqli ( 'localhost' , 'fake_user' , 'my_password' , 'my_db' );
// Works as of PHP 5.2.9 and 5.3.0.
if ( $mysqli -> connect_error ) {
die( 'Connect Error: ' . $mysqli -> connect_error );
}
?>
过程化风格
<?php
$link = @ mysqli_connect ( 'localhost' , 'fake_user' , 'my_password' , 'my_db' );
if (! $link ) {
die( 'Connect Error: ' . mysqli_connect_error ());
}
?>
以上例程会输出:
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.
