addition of 2D(2*2 matrices) array in php.

Hellow.

So today we are sharing a small program which adds elements of 2D Array.

<?php

$a=array(

array(10,20),

array(12,22)
              );

$b=array(

array(11,22),

array(10,21)
         );

$c=array();

for($i=0;$i<count($a);$i++){

for($j=0;$j<count($a);$j++){

             echo "a[$i][$j]";

echo $a[$i][$j]."<br/>";

}
}

  echo "<br/>";

for($i=0;$i<count($a);$i++){

for($j=0;$j<count($a);$j++){

                  echo "b[$i][$j]";

echo $b[$i][$j]."<br/>";

}
}

  echo "<br/>";

    echo "addition of two matrix:<br>            <br>";

  for($i=0;$i<count($a);$i++){

for($j=0;$j<count($a);$j++){

$c[$i][$j]=$a[$i][$j]+$b[$i][$j];

echo "c[$i][$j]";

echo $c[$i][$j]."<br/>";

}

}

?>

Output:-

 so that's it for today.

thank you.
