过程化风格
<?php $link = mysqli_connect("localhost", "my_user", "my_password", "world"); /* check connection */ if (mysqli_connect_errno()) { printf("Connect failed: %s\n", mysqli_connect_error()); exit(); } if (!mysqli_query($link, "SET a=1")) { print_r(mysqli_error_list($link)); } /* close connection */ mysqli_close($link); ?>
