What to do if php redirects IE error

In website development, the redirection function is often used to achieve page jumps. In PHP, redirection can be achieved using the header function, for example:

header('Location: http://www.example.com');
exit;

However, in actual development, we sometimes encounter some problems, one of which is when using the header function for redirection, An error occurred in IE browser. This article will describe the solution in this situation.

1. IE browser error phenomenon

When using the header function for redirection, some IE browsers will pop up an error prompt box;

This is because, When setting the value of Location to a relative path, the IE browser will interpret it as a file system path instead of a network path, resulting in an error.

2. Solution

When this happens, we can have the following solutions:

1. Use the absolute path

to change the Location The value is set to an absolute path, for example:

header('Location: http://www.example.com/index.php');
exit;

This can avoid IE browser’s incorrect interpretation of relative paths.

2. Use output buffering

Use the ob_start function to turn on the output buffering before using the header function, for example:

ob_start();
header('Location: /index.php');
ob_end_flush();
exit;

This ensures that the header function is executed before output, and will The value of Location is set to a relative path.

3. Modify IE settings

Set the "Enable Protected Mode" in the "Non-Security" option of the IE browser to the same or uncheck it to solve this problem. However, this method is not very practical since most users will not change IE settings.

4. Summary

When using the header function for redirection, IE browser encounters an error, which may be caused by the relative path being interpreted by IE as an incorrect file system path. In order to avoid this situation from happening, we can use absolute paths, output buffering or modify IE settings to solve the problem.
