This code is supposed to created a multidimensional array, shuffle it, select the first array, and pass the four values to four different variables called $common, $uncommon, $rare, and $superrare.
<?php
//create multidimentional array
$distribution = array
(
array(115, 50, 15, 0),
array(115, 49, 16, 0),
array(115, 48, 17, 0),
array(116, 49, 15, 0),
array(116, 48, 16, 0),
array(116, 47, 17, 0),
array(117, 48, 15, 0),
array(117, 47, 16, 0),
array(117, 46, 17, 0),
array(118, 47, 15, 0),
array(118, 46, 16, 0),
array(118, 45, 17, 0),
array(119, 46, 15, 0),
array(119, 45, 16, 0),
array(119, 44, 17, 0),
array(120, 45, 15, 0),
array(120, 44, 16, 0),
array(120, 43, 17, 0),
);
//shuffle the md-array
shuffle($distribution);
//select first array from $distribution
$slice[] = array_slice($distribution ,0, 1);
//create an array for key values
$cardrarity = array('common', 'uncommon', 'rare', 'superrare');
//combine $cardrarity and $slice
$cardraritycount = array_combine($cardrarity, $slice);
//create a variable for each value in
foreach ($cardraritycount as $key => $value){
$$key = $value;
}
?>
When I view the contents of $slice it looks like this:
Array
(
[0] => Array
(
[0] => Array
(
[0] => 120
[1] => 43
[2] => 17
[3] => 0
)
)
)
When I try and combine $slice with $cardrarity, I get no output when I try and echo the contents. I think my problem is when I'm doing the array slice. Any help would be appreciated.
array_slice($distribution, 0, 1) returns a multi-dimensional array. It's a 1-element array whose first element is the first element of $distribution. If you just want the first element of $distribution, use $distribution[0].
To assign to multiple variables from an array, use an assignment to the list() function.
So the whole thing should be:
list($common, $uncommon, $rare, $superrare) = $distribution[0];
There's no need to complicate such simple things. Simply do this:
// Shuffle the array
shuffle($distribution);
// Assign values to the respective variables
list($common, $uncommon, $rare, $superrare) = $distribution[0];
// Display values
echo $common . "<br />";
echo $uncommon . "<br />";
echo $rare . "<br />";
echo $superrare . "<br />";
Here's the reference:
Not only is array_slice() returning a multi-dimensional array but you are creating even another dimension with $slice[].
Using $distribution[0] you have two options other than list():
shuffle($distribution);
$cardrarity = array('common', 'uncommon', 'rare', 'superrare');
$cardraritycount = array_combine($cardrarity, $distribution[0]);
Then your foreach() works correctly:
foreach ($cardraritycount as $key => $value){
$$key = $value;
}
Or extract() the array as variables:
extract($cardraritycount);
