Array disappearing in foreach loop

Posted on 16th Feb 2014 07:03 pm by admin

Okay, I have this problem where an array will become undefined in a foreach loop.

Here is the function plus a couple comments:
Code: [Select]function mineResources($nation) {
global $db;
$resources = $nation['resources'];

//Right here $resources would work

$sectors = $db->getSectorList($nation['id']);
foreach($sectors as $sector) {
//In here, $resources is empty
$sectorResources = $sector['resources'];
foreach($sectorResources as $key => $sResource) {
//Does nothing because $resources is empty when it gets here.
$resources[$key] += $sResource;
}
}
$db->updateCountryInfo($nation, array("resources" => $resources));
}
$db is a global array that holds database information. $nation is an array that holds a nation's data. All arrays work except for $resources and even $resources work outside of the foreach loops. Any ideas why this is happening?
