How to Iterate over a Two Dimensional Array in PHP ?

Answer

To iterate over a Two Dimensional Array in PHP, you can use nested loops.

✐ Examples

1 Iterating over a 2D Array of Integers

In this example,

We declare and initialize a 2D array of integers named $matrix.
We use nested loops to iterate over the rows and columns of the array.
Inside the inner loop, we access and print each element of the array.

PHP Program

<?php
$matrix = [[0, 1, 2], [1, 2, 3], [2, 3, 4]];
foreach ($matrix as $row) {
    foreach ($row as $element) {
        echo $element . "\n";
    }
}
?>

Output

2 Iterating over a 2D Array of Strings

In this example,

We declare and initialize a 2D array of strings named $matrix.
We use nested loops to iterate over the rows and columns of the array.
Inside the inner loop, we access and print each element of the array.

PHP Program

<?php
$matrix = [['Hello', 'World'], ['PHP', 'JavaScript']];
foreach ($matrix as $row) {
    foreach ($row as $element) {
        echo $element . "\n";
    }
}
?>

Output

Hello
World
