[Tutorial] How to grab IP adress with PHP

[Gaijin]

does the {} get printed also? i mean wouldnt the best way just be fwrite($handle, $ip . "\n");

No...
That's useful when you want to use a variable within a string....

PHP Code:

echo "This will print {$var}s and add s on the end :D..."; 


But your way is also fine, I just like the looks of {}..
