Dynamically Creating a Matrix
When the values of the matrix are not known beforehand or need to be generated dynamically, you can use loops to initialize the matrix.
PHP
<?php $matrix = []; $value = 1; for ( $i = 0; $i < 3; $i ++) { for ( $j = 0; $j < 3; $j ++) { $matrix [ $i ][ $j ] = $value ++; } } // Display the matrix foreach ( $matrix as $row ) { foreach ( $row as $value ) { echo $value . " " ; } echo "\n" ; } ?> |
