This snippet is an interesting way to log errors from your php file into a log file. Just create a php_error.log file somewhere on your server, and add the snippet to your .htaccess file. Don’t forget to modify the log file location on line 7.

# display no errs to user
php_flag display_startup_errors off
php_flag display_errors off
php_flag html_errors off
# log to file
php_flag log_errors on
php_value error_log /location/to/php_error.log
