This article will introduce the flow chart of implementing the multiplication table in PHP.

Create a table

First, we need to create an HTML table and add a style sheet to it to make it more readable. In this example, we use Bootstrap to simplify the style layout. The following is the code:

<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8">
    <title>PHP 九九乘法表流程图</title>
    <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css">
    <style>
        td {
            padding: 10px 20px;
            font-size: 24px;
            text-align: center;
        }
    </style>
</head>
<body>
    <table class="table table-bordered">
        <thead class="thead-light">
            <tr>
                <th scope="col"></th>
                <?php for ($i = 1; $i <= 9; $i++): ?>
                <th scope="col"><?= $i ?></th>
                <?php endfor ?>
            </tr>
        </thead>
        <tbody>
            <?php for ($i = 1; $i <= 9; $i++): ?>
            <tr>
                <th scope="row"><?= $i ?></th>
                <?php for ($j = 1; $j <= 9; $j++): ?>
                <td><?= $i * $j ?></td>
                <?php endfor ?>
            </tr>
            <?php endfor ?>
        </tbody>
    </table>
</body>
</html>

In this code, we use a table to display the multiplication table. The numbers 1 to 9 are displayed in the header, and the results of the product calculation are displayed in the body of the table.

Use PHP to generate tables

We need to use embedded PHP code to generate tables. In this example, we will use two for loops, one to loop over the number of rows and the other to loop over the number of columns. The following is the PHP code:

<table class="table table-bordered">
    <thead class="thead-light">
        <tr>
            <th scope="col"></th>
            <?php for ($i = 1; $i <= 9; $i++): ?>
            <th scope="col"><?= $i ?></th>
            <?php endfor ?>
        </tr>
    </thead>
    <tbody>
        <?php for ($i = 1; $i <= 9; $i++): ?>
        <tr>
            <th scope="row"><?= $i ?></th>
            <?php for ($j = 1; $j <= 9; $j++): ?>
            <td><?= $i * $j ?></td>
            <?php endfor ?>
        </tr>
        <?php endfor ?>
    </tbody>
</table>

In this code, we use an HTML table to display the actual product results. We used two for loops to calculate the product. The outer for loop is responsible for looping the number of rows, and the inner for loop is responsible for looping the number of columns.

In the first for loop, we use the tag to define the header, and use a for loop to add numbers. In the second for loop, we use the tag to add the result, which is equal to $i*$j.

Integrate all the codes and output the results

The following is the complete PHP code:

<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8">
    <title>PHP 九九乘法表流程图</title>
    <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css">
    <style>
        td {
            padding: 10px 20px;
            font-size: 24px;
            text-align: center;
        }
    </style>
</head>
<body>
    <table class="table table-bordered">
        <thead class="thead-light">
            <tr>
                <th scope="col"></th>
                <?php for ($i = 1; $i <= 9; $i++): ?>
                <th scope="col"><?= $i ?></th>
                <?php endfor ?>
            </tr>
        </thead>
        <tbody>
            <?php for ($i = 1; $i <= 9; $i++): ?>
            <tr>
                <th scope="row"><?= $i ?></th>
                <?php for ($j = 1; $j <= 9; $j++): ?>
                <td><?= $i * $j ?></td>
                <?php endfor ?>
            </tr>
            <?php endfor ?>
        </tbody>
    </table>
</body>
</html>

Copy after login

The final output result will be a multiplication table with ninety-nine table, it displays correctly in all modern web browsers. The table contains header and body parts automatically generated by PHP code.
