mysqli

MySQL returns:

#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '<?php

$link = mysqli_connect('localhost','root','root')' at line 1

The teacher doesn’t know what’s going on

Answer 1

I suggest you take a screenshot, and also check whether the mysqli extension is enabled

Answer 2

$link = mysql_connect('localhost','root','root') or die ('出错了');
mysql_connect 你打成了 mysqli_connect
