面向对象风格
<?php
$mysqli = new mysqli ( "localhost" , "nobody" , "" );
if ( mysqli_connect_errno ()) {
printf ( "Connect failed: %s\n" , mysqli_connect_error ());
exit();
}
if (! $mysqli -> query ( "SET a=1" )) {
print_r ( $mysqli -> error_list );
}
$mysqli -> close ();
?>
过程化风格
<?php
$link = mysqli_connect ( "localhost" , "my_user" , "my_password" , "world" );
if ( mysqli_connect_errno ()) {
printf ( "Connect failed: %s\n" , mysqli_connect_error ());
exit();
}
if (! mysqli_query ( $link , "SET a=1" )) {
print_r ( mysqli_error_list ( $link ));
}
mysqli_close ( $link );
?>
以上例程会输出:
Array ( [0] => Array ( [errno] => 1193 [sqlstate] => HY000 [error] => Unknown system variable 'a' ))
