context-sensitive phpinfo() with specification of a path

I wrote a parser in 2019 that prepares and outputs phpinfo() for my OpenSource Hosting-Panel "fruithost".

Here I had found a way to output the phpinfo() with the scope of a previously specified directory, since a hosting user can also create a php.ini in subdirectories.

The special thing about the method was that the whole thing is executed directly via the web server and PHP-FPM and thus exclusively uses the phpinfo(); of a previously specified directory.

Unfortunately for me, I had lost the part at that time due to git stashing, my efforts to recover the file (here I have already exhausted all conceivable possibilities) were in vain.

Now I want to start the whole topic anew and look again for the possibility to implement my intention.

Problem with the story:

I can't just print phpinfo(), because here the configuration is printed, which runs over a completely different context. As you know, there is no phpinfo('/path/to/php.ini') method. 🙄

Using the PHP CLI via php -i -c /destination/path/ does not work here, because the whole thing is executed by php-cli with a different context and also the output does not happen in HTML. In particular, other PHP modules that do not represent the configuration of PHP-FPM are loaded here.

Desired behavior:

On the screenshot you can see what is needed: At the very top right, a domain can be selected. For example example.com or sample.net. The domains are located in the following path:

/var/fruithost/<username>/<domain>/

If the user selects a domain in the upper right corner (example sample.net), phpinfo() uses the directory /var/fruithost/<username>/sample.net/, because a php.ini could be located here.

This base is then used to control the output of phpinfo().

What are the ideas and approaches?

For those interested: I had uploaded a screenshot back when I finished the 2019 part, this is what the result looked like: Preview

Solution

  • I have found a other solution, with better way to call PHP-FPM directly:

    <?php
    # Executement-Path
    $path   = '/var/fruithost/users/admin/' . $this->domain . '/';
    
    # PHP-fpm
    $socket = '/run/php/php8.2-fpm.sock';
    
    # Create temporarely phpinfo();
    $tmp    = '.~fh.tmp.info.php';
    file_put_contents(sprintf('%s%s', $path, $tmp), '<?php phpinfo(); ?>');
    
    $args = '';
    foreach([
        'SCRIPTS_DIR'       => $tmp,
        'HOME'              => $path,
        'PWD'               => $path,
        'DOCUMENT_ROOT'     => $path,
        'SCRIPT_FILENAME'   => sprintf('%s%s', $path, $tmp),
        'REQUEST_METHOD'    => 'GET'
    ] AS $name => $value) {
        $args .= sprintf('%s=%s \\%s', $name, $value, PHP_EOL);
    }
    
    $command    = sprintf('%scgi-fcgi -bind -connect "%s" 2>&1', $args, $socket);
    $result     = shell_exec($command);
    @unlink(sprintf('%s%s', $path, $tmp));
    
    print_r($result);
?>

    I think my previous version from 2019 has no used temporare files, but its another (ugly) way here.
