142. PHP Program to find Transpose of the given matrix.
How does this program work?
- In this program we are going to learn about how to find transpose of the given matrix using PHP.
- Transpose of a matrix is obtained by changing rows to columns and columns to rows of given matrix.
Here is the code

<?php
// Elements of matrix a

array(1, 2, 3),
array(4, 5, 6),
array(7, 8, 9)

// To calculates the no.of rows and columns of given matrix
$rows = count($a);
$cols = count($a[0]);
//Calculates transpose of given matrix
for($i = 0; $i < $rows; $i++) {
for($j = 0; $j < $cols; $j++) {
$t[$i][$j] = 0;
//Initially transpose matrix to be declare with 0;
$t[$i][$j] = $a[$j][$i];
//Converts the row of original matrix into column of transposed matrix
}
}
echo("Original matrix is: <br>"); // to print Original matrix
for($i = 0; $i < $rows; $i++) {
for($j = 0; $j < $cols; $j++) {
echo ($a[$i][$j] . " ");
}
echo( "<br>");
}
echo( "Transpose of given matrix is:<br>"); // to print transpose matrix
for($i = 0; $i < $cols; $i++) {
for($j = 0; $j < $rows; $j++) {
echo($t[$i][$j] . " ");
}
echo( "<br>");
}
