How To Make Array Variable Global In PHP Function

Posted On Sat Feb 23, 2008 By hostman In PHP Forums And Topics Discussions About Hyper Text Programming Language Forums

today i had this problem, i had an array and i wanted to use it in a function, but when i tried to use it it wouldn't work. so if you are also having this issue, hopefully you can learn from my mistakes.

lets say for example i have this php code;

<?php
$array_string = array();
$array_string[0] = "zero";
$array_string[1] = "one";
$array_string[2] = "two";
$array_string[3] = "three";
function ($string){
echo $array_string[3];
?>

that wont work, so what you need to do is call the global array in your function, like this:

<?php
$array_string = array();
$array_string[0] = "zero";
$array_string[1] = "one";
$array_string[2] = "two";
$array_string[3] = "three";
function ($string){
global $array_string;
echo $array_string[3];
?>

- at - Julie; I have the same problem. A function that calls a global array will work on my localhost, but when live, the function does not work. The array is not recognized as global any more. Also, variables set to 0 (zero, not "NULL") behave properly on my localhost, but are imported to the function that calls them as global variables as "NULL" values when I use a live site (GODADDY). Anyone have a solution for this?

Use your custom keys?

function add(){
global $array_string;
echo $array_string['first'];
}

So is there a version of php where an array can't be declared global in a function? My array is blank when I get to the function. Declaring it exactly as
$array_string = array(
'first' => 'example',
'second' => 'example');
function add() {
global $array_string;
echo $array_string[0];
}
comes up empty. any ideas?

Doesn't work when you try to access the array in a class constructor.
