Why do we not pass the $user_ip variable as an argument to the function?
-
Why does my
echo $user_ip = $_SERVER['REMOTE_ADDER'];REMOTE_ADDER act as a string??? It does not return me my ip
-
perfect! thanks
-
If you're getting "::1", don't worry, you just have to download more memory.
-
So…"global" just tells the function it needs to find a function outside of it? Gotcha
-
<?php
echo $user_ip = $_SERVER["REMOTE_ADDR"];
?>This is all that shows up on my screen "::1". Using xampp with windows 10, chrome and firefox.

wouldn't it be easier to say public … blah blah instead of stating its global?
-
Ok I get it, but will it make it global in all other functions i have written too?

Can I use the global keyword outside the function, just before the variable declaration?

Find your h t tp d . conf file for apache and look for Listen 80. When you find it change it to Listen 127.0.0.1:80. Save the file and then restart your server. Worked for me. It may be different for you.

When I outputted the user_up the result was this, :::1
-
English could be good too, if you used it properly ^^
