Use two loops, one for row and another for column. Fr matrix form, use the tab \t in the nested loop like his −
twoDimensionalArray[row][col],"\t";
Example
<!DOCTYPE html>
<html>
<body>
<?php
$twoDimensionalArray = [];
$value=7;
for ($row = 0; $row <=2; $row++) {
for ($col = 0; $col <=2; $col++) {
$twoDimensionalArray[row][col] = $value;
}
}
for ($row = 0; $row <=2; $row++) {
for ($col = 0; $col <=2; $col++) {
echo $twoDimensionalArray[row][col],"\t";
}
echo "<br>";
}
?>
</body>
</html>Output
777 777 777
Above, you can see the output is in matrix form 3x3.
