Where does PHP's error log reside in XAMPP?

\xampp\php\logs did not exist at all for me - for whatever reason.

I simply had to create a folder in \xampp\php\ called logs and then the php_error_log file was created and written to.

You can simply check your log path from phpMyAdmin.

Run this:

http://localhost/dashboard/

Now click PHPInfo (top right corner) or you can simply open this URL in your browser:

http://localhost/dashboard/phpinfo.php

Now search for "error_log"(without quotes). You will get the log path.

\xampp\apache\logs\error.log is the default location of error logs in PHP.

By default, the XAMPP PHP log file path is in /xampp_installation_folder/php/logs/php_error_log, but I noticed that sometimes it would not be generated automatically. Maybe it could be a Windows account write permission problem? I am not sure, but I created the logs folder and php_error_log file manually and then PHP logs were logged in it finally.

As said in previous answers, you can find the PHP error log in Windows. In C:\xampp\apache\logs\error.log. You can easily display the last logs by tail -f .\error.log.

For Mac users, it can be found in:

/Applications/XAMPP/xamppfiles/logs/php_error_log

In the current version I've just installed (8.0.11) the installer "forgets" to create the folder C:\xamppp\php\logs, perhaps by design. After creating the folder and restarting Apache the folder will be populated with a php_error.log file.

To keep seeing the last entry (much like *nix sh tail -f) use the following command:

Get-Content c:\xampp\php\logs\php_error.log -Wait

This will keep reading the file and display the last entries. Quite handy if you are debugging.
