Answer 1

Change the single quotes surrounding the string you are writing to the file to doubles quotes. So:

file_put_contents("/home/files/1/741/html/WP/$GDI_user/config.php",'');

...becomes...

file_put_contents("/home/files/1/741/html/WP/$GDI_user/config.php","");

A couple of thoughts on this operation

• Don't use PHP short tags - use instead of as short tags are not supported everwhere and are disabled by default on new PHP installations
• Don't put new-line literals in the middle of quoted strings, use HEREDOC syntax if you want to do that. It's best to avoid this if possible as it can lead to cross-platform compatibility issues. Use \r, \n, \r\n and the PHP_EOL constant instead.
• Read this thoroughly so you know exactly what you can and can't do, and where.
