How to Print Calculation Table in Php

In today tutorial I will teach you that how to print table of given value. For example if the given number is 5 then table will look like this

5 x 1 = 5
5 x 2 = 10
and so on

So lets start our tutorials. Look at below code

<?php
$num = 5;
for($i=1;$i<=10;$i++){
echo $num . ' X ' . $i . ' = ' . $i*$num . '<br>' ;
}
?>

<?php

$num = 5;

for($i=1;$i<=10;$i++){

echo $num . ' X ' . $i . ' = ' . $i*$num . '<br>' ;

}

You can see the code is very very simple. You just store value in $num variable and then with for() loop first you echo $num variable then with . you separate next value then print x then print $i and at last we multiply $i and $num.

On the above code you have to change $num in coding view but the code that I am giving below will get value from user and then print the table of given value. It involves some html tags but logic is same as above.

<html>
<head>
<title>
School Days Table
</title>
</head>
<body>
<form action="index.php" method="post">
<input type="text" name="num" />
<input type="submit" value="Show Table" />
</form>
<table>
</table>
<?php
if(isset($_POST['num'])){
$num = $_POST['num'];
?>
    <table border="1" width="120">
    <tr>
    <td colspan="5"> Table of <?php echo $num; ?></td>
    </tr>
    <?php
    
for($i=1;$i<=10;$i++){
?>
<tr>
<td> <?php echo $num; ?></td>
<td> x </td>
<td> <?php echo $i; ?></td>
<td> = </td>
<td> <?php echo $i*$num; ?></td>
</tr>
<?php } ?>
</table>
<?php
} 
else {
echo "";
}
?>
</body>
</html>
