The solution to the problem that the file exists but require_once(./*.php) has an error

Problem description:

I just installed PMA, and when I access it in Firefox, I see a whiteboard and nothing is output. You can see the 500 error (server internal error) using IE

After opening the error report, I found

Warning: require_once(./libraries/common.inc.php) [function .require-once]: failed to open stream: No such file or directory in ***\mousebomb\pma\index.php on line 35

Fatal error: require_once() [function.require]: Failed opening required './libraries/common.inc.php' (include_path='.;C:\php5\pear') in ***\mousebomb\pma\index.php on line 35

The file does exist and IUSR (IIS anonymous access user) has permissions.

Solution:

Whiteboard solution: Modify the relevant error output settings in php.ini. The default php.ini only needs to change display_error=off to display_error =on can

require error resolution: require all relative path files starting with ./, the IUSR of the upper-level directory must be enabled with readable permissions. Not only when configuring PMA, no matter what website, under wimp, you must pay attention to the fact that files starting with ./ must be readable by the upper-level directory if you want to access them.

Sometimes after installing PHPmyAdmin, the following situation will occur when accessing it in IE:

Warning: require_once(./libraries/ common.lib.php): failed to open stream: No such file or directory in ***\index.php on line 40
Fatal error: main(): Failed opening required './libraries/common.lib. php' (include_path='.;c:\php5\pear') in ***\index.php on line 40

The reasons for this problem are as follows:

1. Your PHPmyAdmin directory is placed in the root directory of the disk.
2. The permission settings of your PHPmyAdmin directory and the upper directory

Solution:

·Remove the PHPmyAdmin directory Place it in the root directory of the disk, such as D:\SiteManage\phpmyadmin
. Set the permissions for the PHPmyAdmin directory and the upper directory as follows:
Users　Read and run
IUSR_……Read and Run

Encountered a strange problem. After installing phpmyadmin, the following error is reported:
Warning: require_once(./libraries/common.lib.php) [function.require-once]: failed to open stream: No such file or directory in X:\Xxxxx\ phpmyadmin\index.php on line 36
Fatal error: require_once() [function.require]: Failed opening required './libraries/common.lib.php' (include_path='.;C:\php5\pear' ) in

After a while of debugging, I finally found the solution: The original upper-level ACls permissions of phpmyadmin and php installation directories are not enough, ha! Give phpmyadmin, php, and the same Acls users of their upper-level directories Read rights; then open the Blog and it’s done successfully! ^_^

Notes and security risks:
1. Please do not install phpmyadmin in the root directory of the site or virtual host, because then the guest user will have the permissions of the root directory .
2. Give phpmyadmin the IIS process running user and IIS anonymous User read permissions. It is strongly recommended not to add everyone to the ACLs permission list.
3. When you are debugging a program or configuring a script environment, please try to read as many FAQs as possible first! Then look for the reason from the error code... (For example, in the above error message, you open line 36 of index.php and see PHP codeYou will know the cause of the error by executing the command)

Note tips:

1. Do not unzip phpmyadmin and install it in the root directory, because this will cause the guest user will have the permissions of the root directory.

2. Give phpmyadmin the iis user rights and the user group user rights. It is not recommended to add everyone permission.
