写代码为什么总是出现这种奇怪的现象?

Jun 20, 2016 pm 12:41 PM

之前代码里有一句alert(发布成功)这样的话 我明明已经删除了 为什么还是弹出来这个呢 
还有我写好的页面为了备份 把写好的1.php和2.php的代码都复制出来然后再新建5.php和6.php文件复制进去 为什么6.php里面我写的跳转页面还是跳到1.php里面呢 我明明写的是跳转到5.php啊 这是为什么啊 老是这样 真是气死了 谁能帮帮我啊


回复讨论(解决方案)

这是代码 大家帮我看看  明明写的由6.php跳到5.php 却每次跳到一个不相关的3.php上面
5.php
header ( " Pragma: no-cache " );
$pdo=new PDO("mysql:host=localhost;dbname=t1","root","");
 $sth=$pdo->query('select * from blog2');
 $result = $sth->fetchall(PDO::FETCH_ASSOC);
 foreach($result as $v){
    echo $v['type'];
    echo $v['content'];
 };
?>








            
            


    
    





6.php 如下

header ( " Pragma: no-cache " );
 $pdo=new PDO("mysql:host=localhost;dbname=t1","root","");
 $pdo->exec("INSERT INTO blog2 (type,name,num,content)  VALUES ('$_POST[select]','$_POST[name]','$_POST[num]','$_POST[content]')");
 header("location:http://localhost/blog5.php");
?>

是不是有缓存。
看代码没有问题。

   echo $v['type'];
    echo $v['content'];

这里会不会有js代码,所以执行了?

对缓存不懂啊   我把3.php的页面删除了  现在提交内容后跳转地址又变成了blog.php了   真是奇怪

换个浏览器看看

换个浏览器看看


换了四个浏览器  还是这样

而且我提交后 我查看数据库里面 并没有数据插入进去

6.php跳转的是blog5.php啊。你文件名到底叫什么?

6.php跳转的是blog5.php啊。你文件名到底叫什么?


文件名没错  就是blog5.PHP   不是5.PHP  我只是举例子

从5就没有跳转到6   如果跳转了不可能数据库没有东西


这个 blog.php 是你说的 6 吗?

你把问题描述的云山雾罩的,不提供真实的情况,让人家如何帮你

5.PHP和blog5一样 写错了  我刚才提问时写成了5.PHP

这个页面为什么会乱跳转呢  跟我装的wamp有关系吗

再说一遍


blog.php 才是处理表单提交的程序!!!

应该就是缓存搞的鬼。

再说一遍


blog.php 才是处理表单提交的程序!!!
我刚下班才看到回复  你说的是什么意思呢? 我写的只有blog5.PHP和blog6.PHP文件 不牵扯到blog.PHP文件啊   能否详细说一下呢?谢谢

Web服务器的缓存问题或者浏览器本身的缓存问题,把Apache或者浏览器重启一下就OK了

再说一遍


blog.php 才是处理表单提交的程序!!!

我刚才看了一遍代码  确实因为粗心写错了 太不应该了  谢谢

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.
