Resolved file_put_contents() permission denied in extension

[jimlongo56]

In my extension I'm trying to open and write to a file on the server.

I have the absolute path to the file ($filepath) and when I run

$contents = @file_get_contents($filepath) ?: ''; 
$s = 'some string';
$file_put_contents($contents, $s);

I get the following errors

PHP Warning: file_put_contents(/var/www/vhosts/jim.com/art.janis/.htaccess): failed to open stream: Permission denied

I have run

$ plesk repair installation -y -v
$ plesk repair all -y -v

I have checked that su_exec is enabled in Apache

What are the permissions of that .htaccess file?
# ll /var/www/vhosts/jim.com/art.janis/.htaccess

Thanks Peter for your question.

I've been advised by Support not to use the native functions, but instead to use pm_FileManager()

        $fileManager = new pm_FileManager($domainId);
        $contents = $fileManager->fileGetContents($file);
        // do something with $contents
        $fileManager->filePutContents($file, $newContent);

Extensions API Documentation - Plesk 17.5
Extensions API Documentation - Plesk 17.5

Not clear to me what fileGetContents() returns if the file is not there, may need to check if fileExists() first.
Also not clear if filePutContents() creates a file if none exists yet (native file_put_contents() does this).

This seems to cover the bases,

Is there a file
If not create it
Get the contents
Put the new contents

        $fileManager = new pm_FileManager($domainId);
        if(!$fileManager->fileExists($file)){
            $fileManager->touch($file);
        }
        $contents = $fileManager->fileGetContents($file);
     
        // do some manipulation of the $contents 

        $fileManager->filePutContents($file, $new_contents);
