PHP和Apache - chown（）使用Apache所有者：group？

Question

I'm creating tests for an application that has 3 environments: dev, staging, and production.

I want to run a test which programmatically pulls the default apache owner and group (from httpd.conf), and checks to make sure the uploads directory is owned by this same owner/group combo.

Is there a PHP function that is capable of pulling this data?

Just run the PHP script below.

Don't forget to change the input data for your setup:
$apacheEnvVarsConfFile - the apache conf file that defines the user to be used; in this example it was /etc/apache2/envvars and the line defining it was export APACHE_RUN_USER=www-data
$dirThatYouWantToTest - the directory for which you want to read the user/group permissions

<?php

## define input data
$apacheEnvVarsConfFile = '/etc/apache2/envvars';
$dirThatYouWantToTest = '/var/www';

## compute the information that is needed
$data = array();

$data['apacheUser'] = str_replace('export APACHE_RUN_USER=', '', exec('cat '.$apacheEnvVarsConfFile.' | grep APACHE_RUN_USER'));

$dirStat = stat($dirThatYouWantToTest);
$data['dirTested'] = $dirThatYouWantToTest;
$data['dirUser'] = posix_getpwuid($dirStat[4])['name'];
$data['dirGroup'] = posix_getgrgid($dirStat[5])['name'];
$data['dirPerms'] = substr(sprintf('%o', fileperms($dirThatYouWantToTest)), -4);

echo '<pre>';print_r( $data );echo '</pre>';

## the code above will produce the following output (example): 
/*
Array
(
    [apacheUser] => www-data
    [dirTested] => /var/www
    [dirUser] => john
    [dirGroup] => john
    [dirPerms] => 0755
)
*/
