PHP设置cookie跳转页面后cookie值丢失

本帖最后由 opopen 于 2015-08-12 22:54:00 编辑 问题就是,我输入正确的用户名和密码,还是照样让我重新登陆
在index.php页面获取不到cookie里面的值
主页是判断是否设置用户名,没有设置就返回设置,大牛们帮忙看下什么情况!

我贴一下代码:
<br /><br /><?php<br />//Login.php<br />//清空cookies<br />function clearCookies(){<br />		setCookie('username','',time()-3600);  //删除cookies中标识符为username的变量的值<br />		setCookie('isLogin','',time()-3600);      //删除cookies中标识符为isLogin的变量的值 <br />		setCookie('userpass','',time()-3600);      //删除cookies中标识符为userpass的变量的值 <br />}<br />//判断用户是否登录<br />	//if($_GET['action']=='login')<br />//	{<br />		clearCookies();<br />		$inputname = $_GET['loginname'];<br />		$inputpass = $_GET['loginpass'];<br />		echo '获取到用户名后立即输出'.$inputname.'</br>';<br />		echo '获取到密码后立即输出'.$inputpass.'</br>';<br />		//插入数据库<br />		$host = "localhost";<br />		$user = "root";<br />		$password = "";<br />		$dbname = "test";<br />		$connection = mysql_connect($host,$user,$password);<br />		//echo $connection;<br />		if($connection)<br />		{<br />			//$password = md5($password);<br />			echo '此处是密码'.$inputpass.'</br>';<br />			echo '此处是用户名'.$inputname.'</br>';<br />			<br />			mysql_select_db($dbname,$connection);<br />			echo "数据库链接成功了".'</br>';<br />			$sql = "   SELECT * FROM  `user_info`  where `uname`='$inputname' and `upass` = '$inputpass' ";<br />			echo $sql;<br />			$result = mysql_query($sql);<br />				if($result)<br />				{<br />					$row = mysql_fetch_array($result);<br />					if($row)<br />					{<br />						var_dump($row);<br />						setcookie("username",$row['uname'],time()+3600*24,'/');<br />						setcookie("userpass",$row['upass'],time()+3600*24,'/');<br />						setCookie('isLogin','login',time()+3600*24,'/'); <br />						//echo $_COOKIE["isLogin"];<br />						//echo $checklogin;<br />						//echo $checkloginvalue;<br />						//$home_url = 'index.php';<br />						mysql_close($connection);<br />						//echo "<script language='javascript'> alert(\"欢迎您,${row}['uname']\");window.location='../index.html'</script>";<br />						header("location:index.php");<br />						<br />					}else<br />					{<br />						die("登录失败");<br />					}<br />				}<br />		}<br />		else{<br />				echo "数据库链接失败";<br />		}<br />		<br />	//}<br />	<br />?><br />

接下来是主页:index.php
<br /><?php<br /><br />	$username = $_COOKIE["username"]; <br />	var_dump($username);<br />	echo '此处输出Cookie里面的用户名'.$username;<br />	if($username=="" || $username==null)<br />	{<br />					echo"我进来了";<br />					//header("location:login.html");<br />					<br />					exit;<br />	}<br />?><br />

------解决思路----------------------
我试了下,可以登陆的,cookie也写入成功了,截图给你看

How does PHP type hinting work, including scalar types, return types, union types, and nullable types?How does PHP type hinting work, including scalar types, return types, union types, and nullable types?Apr 17, 2025 am 12:25 AM

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values ​​and handle functions that may return null values.

How does PHP handle object cloning (clone keyword) and the __clone magic method?How does PHP handle object cloning (clone keyword) and the __clone magic method?Apr 17, 2025 am 12:24 AM

In PHP, use the clone keyword to create a copy of the object and customize the cloning behavior through the \_\_clone magic method. 1. Use the clone keyword to make a shallow copy, cloning the object's properties but not the object's properties. 2. The \_\_clone method can deeply copy nested objects to avoid shallow copying problems. 3. Pay attention to avoid circular references and performance problems in cloning, and optimize cloning operations to improve efficiency.

Describe different HTTP caching headers (e.g., Cache-Control, ETag, Last-Modified).Describe different HTTP caching headers (e.g., Cache-Control, ETag, Last-Modified).Apr 17, 2025 am 12:22 AM

Key players in HTTP cache headers include Cache-Control, ETag, and Last-Modified. 1.Cache-Control is used to control caching policies. Example: Cache-Control:max-age=3600,public. 2. ETag verifies resource changes through unique identifiers, example: ETag: "686897696a7c876b7e". 3.Last-Modified indicates the resource's last modification time, example: Last-Modified:Wed,21Oct201507:28:00GMT.

Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1?Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1?Apr 17, 2025 am 12:06 AM

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values ​​to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.
