How to change name of array in PHP using a POST result

Question

Suppose I have 2 arrays $test24 and $test48 . Now if I receive a web form POST $type value 24 I need to execute this

foreach ($test24 as $val) 
{
code here
}

while if I receive a web form POST $type value 48 I need to execute this

foreach ($test48 as $val) 
{
code here
}

I am trying to aggregate/merge the code above in a single foreach in this way

foreach ($test$type as $val) 
{
 code here
}

or this

foreach ($test.$type as $val) 
{
code here
}

but none of these two solutions works , do you know a solution ?

Format of variable for your case is:

foreach (${'test' . $type} as $val)

But I advise you to use array instead of two variables:

$test = [24 => [1,2,3], 48 => [4,5,6]];


foreach ($test[$type] as $val) {
    echo $val;
}
