PHP convert associative array into indexed array - php

Question

So long story short, I have the array $total which looks like this:
Array (
[0] => Array
(
[0] => 1
[1] => 3
)
[1] => Array
(
[0] => 6
[1] => 7
[2] => 8
)
[2] => Array
(
[0] => 9
[1] => 10
)
)
However I need to pass it to a function that looks like this:
$count = cartesian(
Array("GH20"),
Array(1,3),
Array(6,7,8),
Array(9,10)
);
I have asked a similar question but I suspect the answer they gave was correct, I do not think asked the question in the right way. The cartesain function does not seem to accept:
$count = cartesian(
Array($total[0]),
Array($total[1]),
Array($total[2])
);
After some digging around I believe this is down to the fact that the arrays have keys which is not causing an error however instead of any values being returned, it just returns "array" for everything.
My question, in two parts then, is how do I remove the keys from the arrays so it is formatted as required. If possible, could the be done dynamically?
I have tried what everybody suggestes on google which is use the array_values() function, but this did not help
Any help is greatly appreciated, thanks, Nick
As requested, casertain function:
function cartesian() {
$_ = func_get_args();
if(count($_) == 0)
return array(array());
$a = array_shift($_);
$c = call_user_func_array(__FUNCTION__, $_);
$r = array();
foreach($a as $v)
foreach($c as $p)
$r[] = array_merge(array($v), $p);
return $r;
}
This is my desired output (Every permutation of ($total):
Array (
[0] => Array (
[0] => GH20
[1] => 1
[2] => 6
[3] => 9
)
[1] => Array (
[0] => GH20
[1] => 1
[2] => 6
[3] => 10
)
[2] => Array (
[0] => GH20
[1] => 1
[2] => 7
[3] => 9
)
[3] => Array (
[0] => GH20
[1] => 1
[2] => 7
[3] => 10
)
[4] => Array (
[0] => GH20
[1] => 1
[2] => 8
[3] => 9
)
[5] => Array (
[0] => GH20
[1] => 1
[2] => 8
[3] => 10
)
[6] => Array (
[0] => GH20
[1] => 3
[2] => 6
[3] => 9
)
[7] => Array (
[0] => GH20
[1] => 3
[2] => 6
[3] => 10
)
[8] => Array (
[0] => GH20
[1] => 3
[2] => 7
[3] => 9
)
[9] => Array (
[0] => GH20
[1] => 3
[2] => 7
[3] => 10
)
[10] => Array (
[0] => GH20
[1] => 3
[2] => 8
[3] => 9
)
[11] => Array (
[0] => GH20
[1] => 3
[2] => 8
[3] => 10
)
)
