浏览php页面时出现内部服务器错误
[英]internal server error while navigating php pages
问题描述
I am fetching data from mysql table and populating table in HTML .In each table row i have remove button that calls remove.php and remove that row from mysql table and again return to admin.php. 
我正在从mysql表中获取数据并以HTML填充表。在每个表行中，我都有remove按钮，该按钮调用remove.php并从mysql表中删除该行，然后再次返回admin.php。 Problem is when i click the remove button it is executing the php script removing row from table in the database.Then i am navigating again to admin.php While navigating wamp server gives 500 Internal Server error. 问题是当我单击删除按钮时，它正在执行php脚本，从数据库表中删除行。然后我再次导航到admin.php，同时浏览wamp服务器会出现500 Internal Server错误。 What i want is to execute delete query and again return to admin.php. 我想要执行删除查询，然后再次返回admin.php。 So that admin.php gives me updated data. 这样admin.php给了我更新的数据。 I am understanding what is going wrong. 我了解发生了什么问题。

You have an error in your header() function, you are using: 您的header()函数出错，您正在使用：
header("location : admin.php");
This will throw the error you're getting because of the extra space between location and the colon. 由于location和冒号之间有多余的空间，因此会抛出错误。 Change it to this (notice the space): 更改为此（注意空格）：
header("Location: admin.php");
