我尝试使用php登录,但是我得到了这个错误:Warning: mysqli_real_escape_string() expects exactly 2 parameters, 1 given,我做错了什么？

你是混合mysqli和mysql功能.
如果你正在使用mysql函数,那么改为mysqli_real_escape_string($your_variable);使用
$username = mysql_real_escape_string($_POST['username']);
$pass = mysql_real_escape_string($_POST['pass']);
$pass1 = mysql_real_escape_string($_POST['pass1']);
$email = mysql_real_escape_string($_POST['email']);
如果你使用mysqli_*函数,那么你必须将你的数据库连接包含到mysqli_real_escape函数中:
$username = mysqli_real_escape_string($your_connection, $_POST['username']);
$pass = mysqli_real_escape_string($your_connection, $_POST['pass']);
$pass1 = mysqli_real_escape_string($your_connection, $_POST['pass1']);
$email = mysqli_real_escape_string($your_connection, $_POST['email']);
注意:使用mysqli_*函数,因为不推荐使用mysql.有关信息,请阅读mysqli_*
