You might get an error similar to this when writing a php application: Fatal error: Cannot redeclare functioX() in C:\Users\Jared\htdocs\list.php on line 24.
This post will help you understand what an array is and how it is used.
This will be a Homer Simpson “doh” moment for you as much as it was for me. When calling Super Global Variables you have to use “” instead of “()”.
The code should look something like this:
echo "Your IP address is: " . $_SERVER['REMOTE_ADDR'];
The reason why you have to use  instead of () is that the $_SERVER variable is an array and not an object/function. Hope this helps!
This post will go over the “Zend Framework PHP Coding Standard” in a very brief overview. Like most things I tend to use this website as reminders to myself. I hope this helps you as well 😉
