How To Use Multidimensional Array With Example In PHP

Posted By Bajarangi soft , Posted On 24-09-2020

Multidimensional array is an array of arrays. multidimensional arrays that are two, three, four, five, or more levels deep but hard to manage more than three levels.

1. Two-dimensional Arrays.
A two-dimensional array is an array of arrays.

Example(1)

<?php
$bikes = array (
    array("Bike-1",35,'43,174'),
    array("Bike-2",40,'49,174 '),
    array("Bike-3",42,'53,174'),
    array("Bike-4",17,' 70,174')
);
echo "<h4> Model ". $bikes[0][0].": Mileage: ".$bikes[0][1]."kmpl, cost: ".$bikes[0][2].".</h4>";
echo "<h4> Model ". $bikes[1][0].": Mileage: ".$bikes[1][1]."kmpl, cost: ".$bikes[1][2].".</h4>";
echo "<h4> Model ". $bikes[2][0].": Mileage: ".$bikes[2][1]."kmpl, cost: ".$bikes[2][2].".</h4>";
echo "<h4> Model ". $bikes[3][0].": Mileage: ".$bikes[3][1]."kmpl, cost: ".$bikes[3][2].".</h4>";
?>

We Can also Use Loop For Two-dimensional Arrays:
Print all the values of Two-dimensional Arrays through the foreach loop.

Example(2)

<?php
$bikes = array(
    array("Bike-1", '35 kmpl', 'Rs. 43,174 '),
    array("Bike-2", '40 kmpl', 'Rs. 49,174 '),
    array("Bike-3", '42 kmpl', 'Rs. 53,174 '),
    array("Bike-4", '17 kmpl', 'Rs. 70,174 ')
);
foreach ($bikes as $mark) {
    echo "<br>";
    echo "<h4>" . $mark[0] . "</h4>";
    echo "<h4>" . $mark[1] . "</h4>";
    echo "<h4>" . $mark[2] . "</h4>";
}
?>
