Linux – PHP debugging under Apache on CentOS 5.9

apache-2.2centos5linuxPHPvbulletin

After upgrading a vBulletin installation, accessing any page tells me that files are missing–even though they exist in the filesystem.

Based on other questions I found here, I have tried changing the file permissions to no avail, changing the error log directive and php.ini, and changed ownership of the files it's trying to access.

Nothing I do seems to give me an informative error message. Running the scripts from the command line fail to give me the same errors, so that doesn't help.

Is there any way to execute a php file from the command line as if it was running under Apache? I'm hoping that might produce more informative errors.

EDIT: it was a permissions issue on the directory. includes/datastore was 644 instead of 755.

…still don't know how to get informative php error messages. 🙁

"Is there any way to execute a php file from the command line as if it was running under Apache?"

Either you can run a php script from command line using php cli eg :

 php /path/to/myscript

But it won't execute it "as if it was running under Apache".

Either you can call the page from command line using curl or wget, but it won't be useful for debugging.

Php – How to make the Apache/PHP setup on the VPS show PHP errors and warnings

Normally, web applications will log errors to the Apache error log. This is the file specified in the relevant ErrorLog setting for your server or virtual host section. PHP applications will send logs there, but they aren't entirely the most accessible or useful logs; your logging can get lost between other errors. PHP can be configured to log to a separate log file, but this is not very different from logging to the Apache error log. You can configure Apache to log errors to the browser using

display_errors = On

in your php.ini. With this, log lines will appear in your browser. You really should not use this option on a production system. If you need to mix production and development applications on the same system, you can use:

ini_set("display_errors","On");

at the top of your development php files.

The error_reporting option changes what PHP reports.

You can do better though. XDebug is a PHP extension which adds some very useful PHP development features, like stack traces, profiling and code coverage.

Linux – Correct user / permissions for running php script which writes to disk

If contacts.txt exists, then the permissions on contacts.txt needs to be changed, probably to 666. If it doesn't, then the permissions on the directory you want it to be in needs to be changed to allow the webserver to write to it.

The first way is the way you want to do it, especially if there's anything else in the directory you don't want to let web users write over.
