我是 php 新手,想知道是否有人可以帮助我调试,出现以下错误。致命错误:调用未定义的函数 session_register()
它发生在我让用户登录时。
PHP
<?php
include("config.php");
session_start();
if($_SERVER["REQUEST_METHOD"] == "POST")
{
// username and password sent from Form
$myusername=addslashes($_POST['username']);
$mypassword=addslashes($_POST['password']);
$sql="SELECT id FROM admin WHERE username='$myusername' and passcode='$mypassword'";
$result=mysql_query($sql);
$row=mysql_fetch_array($result);
$active=$row['active'];
$count=mysql_num_rows($result);
// If result matched $myusername and $mypassword, table row must be 1 row
if($count==1)
{
session_register("myusername");
$_SESSION['login_user']=$myusername;
header("location: welcome.php");
}
else
{
$error="Your Login Name or Password is invalid";
}
}
?>
它在第 16 行抛出的错误是
$active=$row['active'];
