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"; } ?> |
Output
1 2 3 4 5 6 7 8 9
