本文实例讲述了ThinkPHP模板Volist标签嵌套循环输出多维数组的方法。分享给大家供大家参考,具体如下:
ThinkPHP 中对 volist 标签嵌套使用可实现多维数组的输出。
volist 嵌套使用
一般的二维数组,可以用 volist 标签直接循环输出。对于多维数组,则需要对其中的数组成员再次使用 volist 标签嵌套循环输出。
构建一个多维数组:
$food = array(); $food[0]['fruits'][0]['fruits1'] = '苹果1'; $food[0]['fruits'][0]['fruits2'] = '桔子1'; $food[0]['fruits'][0]['fruits3'] = '香蕉1'; $food[0]['vegetables'] = '白菜1'; $food[1]['fruits'][1]['fruits1'] = '苹果2'; $food[1]['fruits'][1]['fruits2'] = '桔子2'; $food[1]['fruits'][1]['fruits3'] = '香蕉2'; $food[1]['vegetables'] = '白菜2';
使用 print_r() 函数打印出该数组如下:
Array ( [0] => Array ( [fruits] => Array ( [0] => Array ( [fruits1] => 苹果1 [fruits2] => 桔子1 [fruits3] => 香蕉1 ) ) [vegetables] => 白菜1 ) [1] => Array ( [fruits] => Array ( [1] => Array ( [fruits1] => 苹果2 [fruits2] => 桔子2 [fruits3] => 香蕉2 ) ) [vegetables] => 白菜2 ) )
在对应模块操作(如Index/display)里将变量赋值给模板,并将模板输出:
$this->assign( "food", $food ); $this->display();
模板 Tpl/default/Index/display.html :
<p>食物品种:</p><br /> <volist name="food" id="vo"> <volist name="vo['fruits']" id="f"> <p>水果1:{$f['fruits1']}</p> <p>水果2:{$f['fruits2']}</p> <p>水果3:{$f['fruits3']}</p> </volist> <p>蔬菜:{$vo['vegetables']}</p><br /> </volist>
在模板里面,首先将 $food 变量进行循环输出。由于 $food 数组的成员 fruits 也是一个数组,因此再对 $vo['fruits'] 变量进行循环输出(注意没有 $ 符号)。
输出结果如下:
食物品种: 水果1:苹果1 水果2:桔子1 水果3:香蕉1 蔬菜:白菜1 水果1:苹果2 水果2:桔子2 水果3:香蕉2 蔬菜:白菜2
同理推之以此方法可以对更多维的数组进行循环输出。

希望本文所述对大家基于ThinkPHP框架的PHP程序设计有所帮助。

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

PHP makes it easy to create interactive web content. 1) Dynamically generate content by embedding HTML and display it in real time based on user input or database data. 2) Process form submission and generate dynamic output to ensure that htmlspecialchars is used to prevent XSS. 3) Use MySQL to create a user registration system, and use password_hash and preprocessing statements to enhance security. Mastering these techniques will improve the efficiency of web development.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.

PHP remains important in modern web development, especially in content management and e-commerce platforms. 1) PHP has a rich ecosystem and strong framework support, such as Laravel and Symfony. 2) Performance optimization can be achieved through OPcache and Nginx. 3) PHP8.0 introduces JIT compiler to improve performance. 4) Cloud-native applications are deployed through Docker and Kubernetes to improve flexibility and scalability.

PHP is suitable for web development, especially in rapid development and processing dynamic content, but is not good at data science and enterprise-level applications. Compared with Python, PHP has more advantages in web development, but is not as good as Python in the field of data science; compared with Java, PHP performs worse in enterprise-level applications, but is more flexible in web development; compared with JavaScript, PHP is more concise in back-end development, but is not as good as JavaScript in front-end development.

PHP and Python each have their own advantages and are suitable for different scenarios. 1.PHP is suitable for web development and provides built-in web servers and rich function libraries. 2. Python is suitable for data science and machine learning, with concise syntax and a powerful standard library. When choosing, it should be decided based on project requirements.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7
