Not surprising, as, in your case, only root can create files in the /var/
log directory and the php process that attempts to file_put_contents() 
to /var/log/error.log does not likely run as root.

 Your ls listing shows
  /var/log drwxr-xr-x 1 root root
which means that only processes run with effective userid of root can
update the directory with new or changed directory entries. That means
that /only root/ can create /var/log/error.log



To fix the problem, either change the permissions of /var/log to
permit your php process to write to it, or run your php process as root.
