Sum of All Matrix Elements using Nested Loops
This PHP program uses nested loops to find the sum of all elements in a matrix. It iterates through each row and column, adding each element to a running total. The final sum is returned as the result.
Example: Implementation to find the sum of all Matrix elements.
PHP
<?php function sumMatrixElements($matrix) { $sum = 0; foreach ($matrix as $row) { foreach ($row as $element) { $sum += $element; } } return $sum; } // Driver code $matrix = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]; $sum = sumMatrixElements($matrix); echo "Sum of all matrix elements: $sum"; ?> |
Output
Sum of all matrix elements: 45
Explanation:
- The
sumMatrixElementsfunction takes a 2D array (matrix) as input. - It uses nested
foreachloops to iterate through each row and each element in the row. - The elements are accumulated in the
$sumvariable, which is returned at the end.
