[RESOLVED] Loop and array help

[ExpendableDecoy]

Hi. 🙂

I'm sure this is an easy fix but I think I've now been looking at this for too long. :oops:

Here's the code I have:

	// First we must work out the rarity of the material found
	$material_rand = rand(1,100);
	if(($material_rand > '99') && ($material_rand < '101')) $material_selector = 28;
	elseif(($material_rand > '89') && ($material_rand < '100')) $material_selector = 27;
	elseif(($material_rand > '64') && ($material_rand < '90')) $material_selector = 2;
	else $material_selector = 1;

// Now we need to pull out only the material item types which == $material_selector
$new_materials = array();
for($i = 0; ($i < count($materials)); $i++)
{
	if($materials[$i]['item_type_use'] == $material_selector)
	{
		$new_materials[] = $materials[$i];
	}
}

// Shuffle new array
$materials = shuffle($new_materials);
$material = $materials[0];
echo 'Mat Name: '.$material['material_name'];

So basically, I need to add the $materials[$i] onto the end of the $new_materials[] array each time the if() is true in the loop.

The $materials[$i] variable will consist of something similar to this:

$materials[] = array(
                        'material_name' => 'Glass',
                        'item_durability' => 0.50,
                        'item_power' => 1,
                        'item_weight' => 0.75,
                        'item_type_use' => 1,
                        'item_price' => rand(1,2),

Any help would be much appreiciated. 🙂

I believe the only problem you have is with using the function [man]shuffle/man . As the manual points out, this function returns a boolean result which, I assume, would reflect the success of the function.

So, you're actually replacing $materials with a TRUE on this line:

$materials = shuffle($new_materials);

Try just calling the function with the array arguement.

Ahh, yeah, that's the issue. I moved the shuffle above the loop and did shuffle($materials) instead and it works just as well.

Thanks. 🙂
