数组拆分问题
假设数组a：
array ( 0 => array ( 'po_num' => 'DYNP-770266110-00', 'plant' => 'DYNP', 'get_date' => '2013-09-09', 'cust_no' => '12647212', 'total' => '60', 'snp' => '15', 'mount' => '4', 'lp_no' => 'P000000D', ), 1 => array ( 'po_num' => 'DYNP-770266110-00', 'plant' => 'DYNP', 'get_date' => '2013-09-09', 'cust_no' => '12654172', 'total' => '615', 'snp' => '15', 'mount' => '41', 'lp_no' => 'P000000D', ),)
当满足整个total为一定条件时，将数组拆分开来。例中total为675，假设拆分条件为total满足225，也就是拆分为3个数组，如何能将数组拆分成这样？
//barray ( 0 => array ( 'po_num' => 'DYNP-770266110-00', 'plant' => 'DYNP', 'get_date' => '2013-09-09', 'cust_no' => '12647212', 'total' => '60', 'snp' => '15', 'mount' => '4', 'lp_no' => 'P000000D', ), 1 => array ( 'po_num' => 'DYNP-770266110-00', 'plant' => 'DYNP', 'get_date' => '2013-09-09', 'cust_no' => '12654172', 'total' => '165', 'snp' => '15', 'mount' => '11', 'lp_no' => 'P000000D', ),)//carray ( 0 => array ( 'po_num' => 'DYNP-770266110-00', 'plant' => 'DYNP', 'get_date' => '2013-09-09', 'cust_no' => '12647212', 'total' => '225', 'snp' => '15', 'mount' => '15', 'lp_no' => 'P000000D', ),）//darray ( 0 => array ( 'po_num' => 'DYNP-770266110-00', 'plant' => 'DYNP', 'get_date' => '2013-09-09', 'cust_no' => '12647212', 'total' => '225', 'snp' => '15', 'mount' => '15', 'lp_no' => 'P000000D', ),）

能不能变成这样？把3组区分出来。

如果mount项的值也发生改变，是不是和这个一样？
$t = 225;foreach($a as $v) { $t1 = $v['total']; $v['total'] = $t1 % $t; $res[] = $v; $t1 -= $v['total']; while($t1 >= $t) { $v['total'] = $t; $t1 -= $t; $res[] = $v; }}print_r($res);能不能获取这样的结果？

当然可以，不过有什么意义呢？
我是想记循环输出的结果，foreach($res1 as $value)这样。

我用了array_chunk，怎么结果变成了这样？

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,
How does session hijacking work and how can you mitigate it in PHP?
Apr 06, 2025 am 12:02 AM
Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.
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.
