How to useIndexed Arrays in PHP
The simplest way to declare and initialize a 3×3 matrix in PHP is by using indexed arrays. Each element of the main array will be another array representing a row in the matrix.
PHP
<?php $matrix = [ [1, 2, 3], // Row 1 [4, 5, 6], // Row 2 [7, 8, 9] // Row 3 ]; // Display the matrix foreach ( $matrix as $row ) { foreach ( $row as $value ) { echo $value . " " ; } echo "\n" ; } ?> |
Output
1 2 3 4 5 6 7 8 9
