Question

I hava a function that looks something like this:

require("config.php");

function displayGta()
{
    (... lots of code...)

    $car = $car_park[3]; 
} 

and a config.php that look something like this:

<?php
$car_park = array ("Mercedes 540 K.", "Chevrolet Coupe.", "Chrysler Imperial.", "Ford Model T.", "Hudson Super.", "Packard Sedan.", "Pontiac Landau.", "Duryea."); 
 (...)
?>

Why do I get Notice: Undefined variable: car_park ?

Answer 1

Try adding

 global $car_park;

in your function. When you include the definition of $car_park, it is creating a global variable, and to access that from within a function, you must declare it as global, or access it through the $GLOBALS superglobal.

See the manual page on variable scope for more information.
