  • I've never seen the `t` option for `fopen`. I'd just use `file_get_contents` and `file_put_contents`. They are much easier. A DB would be a better approach though. – user3783243 Jun 22 '18 at 16:26
  • The image looks like you don't have PHP installed. – user3783243 Jun 22 '18 at 16:27

    php.net is a great place to go for answers http://php.net/manual/en/function.file-get-contents.php and http://php.net/manual/en/function.file-put-contents.php Those will be for after you get the PHP running. They will replace your `fopen`, `fread`, `fwrite`, and `fclose`. – user3783243 Jun 22 '18 at 16:31
  • From my computer A, PHP -V : PHP 7.2.2-1 (cli) (built: Feb 1 2018 15:19:04) ( NTS ) – 3edf1w Jun 22 '18 at 17:05
  • That is command line. Do you have if configured to run from your server software as well? – user3783243 Jun 22 '18 at 18:00
  • /etc/init.d/apache2 restart – 3edf1w Jun 22 '18 at 18:14
  • That just restarts apache, do you have the module installed? – user3783243 Jun 22 '18 at 18:15
  • which module ?? – 3edf1w Jun 22 '18 at 18:27
  • PHP you need apache to know to run PHP. – user3783243 Jun 22 '18 at 20:13
  • i know .. so every time before server to use , i start apache... /etc/init.d/apache2 restart – 3edf1w Jun 22 '18 at 20:45

Edit new my comment... , i had two problem because PHP not display.... . First ,me messing some modules for PHP , libapache2-mod-php7.0..

Seconds ,i not had access right to my Website... , with sudo chown -R www-data:www-data /var/www/html , i have this Right to give.... image how the Website see with the Comments , The Code remain identical...

@user3783243 , today i to red this , how Understand , t convert \n to \r\n , it is ONLY for Windows user.. , Linux ignored it ... .

\n is used for Unix systems (including Linux, and OSX).

\r\n is mainly used on Windows.

\r is used on really old Macs.
