An array matrix in PHP can be a collection of numbers, strings, etc. arranged into a specific number of rows and columns. In PHP, the matrix can be created using a two-dimensional array(an array of arrays).

Matrix in PHP

Here is a PHP program for displaying a 3*3(rows=3,cols=3) matrix in PHP:

<html>
    <body>
        <?php
echo "<b>The matrix is given below:-</b>"."<br>";
$a=array(array()); //declaration of a two dimensional array(here $a)
for($i=0;$i<3;$i=$i+1)
{
    for($j=0;$j<3;$j=$j+1)
    {
        $a[$i][$j]=$i+$j;
        echo $a[$i][$j];
    }
    echo "<br>";
}
        ?>
    </body>
</html>

Output:

The matrix is given below:-
012
123
234

Here $a[$i][$j] is the array element with row index $i and column index $j. Each array element is containing here, a value through the statement $a[$i][$j]=$i+$j and values are displaying with echo $a[$i][$j] statement.
