Answer 1

$myArray = array(1,4,6);

$num1 = $myArray[0];
$num2 = $myArray[1];
$num3 = $myArray[3];

echo $num1; // 1
echo $num2; // 4
echo $num3; // 6

Answer 2

Use this

list($first,$second) = $array;

Answer 3

You can access it directly like this

$data = array(1,4);
echo $data[0];// 1
echo $data[1];// 4

or dynamically

foreach($data as $id){

echo $id;
}
