新手请教PHP怎么批量获取POST值并存入数据库!
$data=array();
$data['a']=in($_POST['a']);
$data['b']=in($_POST['b']);
$data['c']=in($_POST['c]);
$data['d']=in($_POST['d']);
$data['aa']=in($_POST['aa']);
$data['a1']=in($_POST['a1']);
..................这里省略
model('xitong')->update("id=1",$data);
上面是一段正常更新数据库的PHP代码
但是,目前所遇到的问题是,为了需要,这个表里面的字段多达50多个。而像
$data['a']=in($_POST['a']);这样格式一行一行输入的话,感觉很不科学。
能不能做到按照字段名称批量获取post值并一同更新到数据库?
回复讨论(解决方案)
foreach($_POST as $key => $val){ //最好加上逻辑 过滤不是字段的 key $data[$key] = in($val);}
foreach($_POST as $key => $val){ //最好加上逻辑 过滤不是字段的 key $data[$key] = in($val);}
本人新手,能详细点吗,谢谢!
$fields = array('a','b','c','d');//你的字段foreach($fields as $val){ if(!empty($_POST[$val])){ $data[$val] = in($_POST[$val]); }}
$fields = array('a','b','c','d');//你的字段foreach($fields as $val){ if(!empty($_POST[$val])){ $data[$val] = in($_POST[$val]); }}
这种看明白了,
但是在2楼您回复的另外一种方式我试过了也可以用。但不知道两者有什么区别,用哪一张比较好。
第一种的话 如果 psot传了一个 数据库 没有的key 就会报错呀
所有我说要做字段过滤
如果不是 每次都是 插入 所有字段的话可以用这种方法
第二种的话 检查了每个字段都是不是有值
如果每次都是插入所有字段可以使用这种发放
各有各的好处 看使用的人 怎么用

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,

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.

The enumeration function in PHP8.1 enhances the clarity and type safety of the code by defining named constants. 1) Enumerations can be integers, strings or objects, improving code readability and type safety. 2) Enumeration is based on class and supports object-oriented features such as traversal and reflection. 3) Enumeration can be used for comparison and assignment to ensure type safety. 4) Enumeration supports adding methods to implement complex logic. 5) Strict type checking and error handling can avoid common errors. 6) Enumeration reduces magic value and improves maintainability, but pay attention to performance optimization.

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.

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.
