How to use single or multi dimention arrays in PHP

    Usage of arrays in PHP:

    //Declaring Single dimention array
    $single_dim = array("", "", "", "", "");

    //Declaring Multi dimention array
    $multi_dim = array(array("", "", "", "", ""));

    //Defining/Assigning Single dimention array
    $single_dim[0] = "Zero";
    $single_dim[1] = "One";
    $single_dim[2] = "Two";
    $single_dim[3] = "Three";
    $single_dim[4] = "Four";

    //Defining/Assigning Multi dimention array
    //Row1
    $multi_dim[0][0] = "Zero";
    $multi_dim[0][1] = "One";
    $multi_dim[0][2] = "Two";
    $multi_dim[0][3] = "Three";
    $multi_dim[0][4] = "Four";

    //Row2
    $multi_dim[1][0] = "0";
    $multi_dim[1][1] = "1";
    $multi_dim[1][2] = "2";
    $multi_dim[1][3] = "3";
    $multi_dim[1][4] = "4";
    .

    //Accessing/Printing Single dimention array
    for($i = 0; $i < sizeof($single_dim); ++$i)
        echo $single_dim[$i]."<br>";

    //Output
    Zero
    One
    Two
    Three
    Four

    //Accessing/Printing Multi dimention array
    for($i = 0; $i < sizeof($multi_dim); ++$i)
        for($j = 0; $j < 5; ++$j)
            echo $multi_dim[$i][$j]."<br>";

    //Output
    Zero
    One
    Two
    Three
    Four
    0
    1
    2
    3
