Perfect Server CentOS 8, ISPConfig 3.2.6, fully updated, using Mod-PHP setting I have a website defined and working - PHP files that access a MySql database, no issues. wanted to have a PHP file generate some output and store it into a file saved within the same folder as the PHP file, using Code: file_put_contents($path . $filename, $content); where $path is a valid path created using the $_SERVER["DOCUMENT_ROOT"] variable with a hardcoded folder name added to it. I've copy/pasted the resulting path into the command line with a CD command, and it works - it's valid. The permissions on the folder have been set to web15.client11 using "chown -R web15.client11" on the folder - the results match all the other folders in the web directory. this folder is also in the root /web of the website - no parent folders that should be a problem. However, the PHP file gets a permissions error when trying to save the contents to the desired path/file when called from a browser: Code: PHP Warning: file_put_contents(/var/www/mydomain.com/web/myfolder/myfile.txt): failed to open stream: Permission denied in /var/www/clients/client11/web15/web/myfolder/myphpfile.php on line 76 where line 76 is the file_put_contents command above. When I run "php myphpfile.php" from the command line within that folder, it works and creates the desired file with the desired content in it, though I am logged in as root. I was just about to submit this question, when I realized I never searched the ISPConfig forum for the file_put_contents command. Doing so, I found a post that referenced the following: As stated above, I was using Mod-PHP - switched it to Fast-CGI, and it's working (already had suExec checked) Thanks for the forum and the answers!
