PHP的url参数获取问题,如何快速获取所需参数
http://www.abc.com/content/5176.asp?page=1&5176__2#p
当前url是这个链接
我现在需要在当前页面上生成1个链接
http://www.abc.com/content/5176.asp?page=1&author=10000
如何快速完成??
我的做法是:
function ghref($param){ $url = "http://".$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI']; //获取url $query_str = parse_url($url, PHP_URL_QUERY); //获取url问号后的值,不包括# $query_str =explode("&",$query_str); //切割成数组 $arr=array(); foreach($query_str as $v){ if(preg_match("/=/",$v)){ $arr[] = $v; //标准的键名=参数值,就留下 } } $str = implode("&",$arr); //变成url字符串 parse_str($str,$myArray); //再次分成数组形式 $myArray['page']=$param; //修改其中某个键名的值 $myArray['author']=1000; return substr($url,0,strpos($url,"?"))."?".http_build_query($myArray); //完整拼接}
我觉得有点繁琐了,哪路大神有简便的做法???
回复讨论(解决方案)
你的 asp 也用 php 解析?
对于 http://www.abc.com/content/5176.asp?page=1&5176__2#p
$_GET 是这样的数组 array('page' => 1, '5176__2' => ''),#p 不会被 php 利用
于是你可以 $_GET = array_diff($_GET, array('')); 得到这样的数组 array('page' => 1)
$_GET['author'] = 1000;
return ""http://$_SERVER[HTTP_HOST]/$_SERVER[PHP_SELF]?" . http_build_query($_GET);

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.

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,

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.
