PHP - error_log () will not print to file

Question

The name pretty much says it all. I tore my hair, trying to make it work all day. I am in the process of creating a PHP-based login system and I need to do some debugging. The most useful thing for me now is the ability to write debugging messages to a file at specific points throughout the PHP program. Based on the documentation, it looks like this is what I should do error_log(), but despite everything I tried, I had absolutely no success. A complete list of everything I've tried below:

• Added /etc/php/7.0/apache2/php.ini

  following:

  error_reporting = E_ALL
  display_errors = On
  log_errors = On
  

• Also, try setting error_logto locations within /usr/, /var/www/http/and/home/

• Use ini_set()and error_reporting()to set all of these variables, including error_logfrom the PHP file

• Manually create the files to be written to, and set their owner and group to www-dataand their permissions at 777

• And last but not least, reinstallation libapache2-mod-php7.0and php7.0, to no avail

• Basically everything except using my laptop to break the 3-story window of my office building just before proceeding with my alleged death

I really can’t find anything else to try on Google, so I decided that I would ask the experts, and I was here. If anyone can provide any suggestions, we will be very grateful.
