其中
第一条
array (size=3)
1 => string '2' (length=1)
2 => string '304' (length=3)
3 => string '2' (length=1)
array (size=3)
1 => string '3' (length=1)
2 => string '309' (length=3)
3 => string '1' (length=1)
第二条rule_1 是
array (size=3)
1 => string '2' (length=1)
2 => string '128' (length=3)
3 => string '3' (length=1)
既然你喜欢瞒满抗抗的,也就罢了
观察到 rule_1 属于 第三维的关联键,你就弄个二重循环遍历一下就是了
求教
弄个二重循环遍历一下
怎么整? 确实数据不怎么好友
循环出来都麻烦,这个是用在,订单中,每个商品的促销规则不一样,有一个有两个的
没有数据怎么写代码?
难不成还要我给你造些数据?
出来了,谢谢
$nn = 0; foreach($shop_list as $key=>&$val){ for($i=0;$i<count($shop_list);$i++){ if($shop_list[$key][$i]['rule_1']){ var_dump("99999"); $nn = $nn + 1; } } $shop_list[$key]['rule_nu'] = $nn; $nn = 0; } var_dump($shop_list);
大神级别的人都喜欢模拟 数据
谢了, 出来了 出来了
不是喜欢 喜欢模拟数据
而是既然在教你如何做,就必须给能通过测试的代码
糊弄你有什么意思
谢谢 ~~~

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.

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.

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 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

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 type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

PHP and Python have their own advantages and disadvantages, and the choice depends on project needs and personal preferences. 1.PHP is suitable for rapid development and maintenance of large-scale web applications. 2. Python dominates the field of data science and machine learning.

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.
