一个PHP算法方面的计算题。
aaa = trim(request("aaa"))
bbb = trim(request("bbb"))
ccc = trim(request("ccc"))
ddd = trim(request("ddd"))
eee = trim(request("eee"))
fff = trim(request("fff"))
ggg = trim(request("ggg"))
hhh = trim(request("hhh"))
。。。。。。。。。。
。。。。。。。。。。
?>
如何用PHP快速计算出本页面到底接收了几个不为空的参数?,并把参数个数及参数值逐一echo出来。
(注意:这些参数中,如果是带有半角逗号或空格时,需要按照多参数来计算。并用split拆分开,也逐一echo出来)
此问题之前已经有一个很好的ASP写法,由于初学PHP,所以不知道怎么改写为PHP的。
网址如下: http://bbs.csdn.net/topics/391906200
回复讨论(解决方案)
<?php$request = $_REQUEST;foreach($request as $k=>$v){ if(trim($v)!=''){ echo $k .'='.$v.PHP_EOL; }}?>
<?php$request = $_REQUEST;foreach($request as $k=>$v){ if(trim($v)!=''){ echo $k .'='.$v.PHP_EOL; }}?>
谢谢版主,请看私信,因为我还希望有循环功能,以便逐一处理表单每一个字段的数据并写入数据库,保存这些查询条件。
<?php$request = $_REQUEST; foreach($request as $k=>$v){ if(trim($v)!=''){ $v=str_replace(", ",",",$v); $v=str_replace(" ",",",$v); $arr = explode(',', $v); echo "<hr>key:". $k. "<br>"; foreach($arr as $kk=>$vv){ if(trim($vv)!=''){ echo $k.$kk.'--value:'.$vv.'<br>'; } } }}?>
<?php$request = $_REQUEST; foreach($request as $k=>$v){ if(trim($v)!=''){ $v=str_replace(", ",",",$v); $v=str_replace(" ",",",$v); $arr = explode(',', $v); echo "<hr>key:". $k. "<br>"; foreach($arr as $kk=>$vv){ if(trim($vv)!=''){ echo $k.$kk.'--value:'.$vv.'<br>'; } } }}?>
赞一个啊!!版主真棒。

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,

Article discusses late static binding (LSB) in PHP, introduced in PHP 5.3, allowing runtime resolution of static method calls for more flexible inheritance.Main issue: LSB vs. traditional polymorphism; LSB's practical applications and potential perfo

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 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.
