The idea of implementing the ninety-nine multiplication table flow chart in PHP
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 * $j ?></td> <?php endfor ?> </tr> <?php endfor ?> </tbody> </table>
In this code, we use an HTML table to display the actual product results. We used two for loops to calculate the product. The outer for loop is responsible for looping the number of rows, and the inner for loop is responsible for looping the number of columns.
In the first for loop, we use the
- Integrate all the codes and output the results
The following is the complete PHP code:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>PHP 九九乘法表流程图</title>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css">
<style>
td {
padding: 10px 20px;
font-size: 24px;
text-align: center;
}
</style>
</head>
<body>
<table class="table table-bordered">
<thead class="thead-light">
<tr>
<th scope="col"></th>
<?php for ($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>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.
In this article, we introduce the flow chart of how to implement the multiplication table in PHP. We hope it will be helpful to you.

Explain JSON Web Tokens (JWT) and their use case in PHP APIs.
Apr 05, 2025 am 12:04 AM
JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
Describe the SOLID principles and how they apply to PHP development.
Apr 03, 2025 am 12:04 AM
The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.

Explain late static binding in PHP (static::).
Apr 03, 2025 am 12:04 AM
Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
