php.ini

PHP settings are defined in: - a main configuration file, usually found under /etc/php5/php.ini; some distributions provide different configuration environments, e.g. - /etc/php5/php.ini - used when running console scripts - /etc/php5/apache2/php.ini - used when a client requests PHP resources from Apache - /etc/php5/php-fpm.conf - used when PHP requests are proxied to PHP-FPM - additional configuration files/entries, depending on the installed/enabled extensions: - /etc/php/conf.d/xdebug.ini

Server environment

  • create a phpinfo.php script located in a path supported by the web server, e.g.
    • Apache (with user dirs enabled): /home/myself/public_html/phpinfo.php
    • /var/www/test/phpinfo.php
  • make sure the script is readable by the web server user/group (usually, www, www-data or httpd)
  • access the script from a web browser
  • look at the Loaded Configuration File and Scan this dir for additional .ini files entries
<?php phpinfo(); ?>
