Three ways to delete a directory using php rmdir
I will introduce to you three methods of deleting a directory using the rmdir command in PHP. Friends in need can refer to it.
1. Submission of regulations <?php //递归删除目录 //by bbs.it-home.org deleteDir($dir) { if (rmdir($dir)==false && is_dir($dir)) { if ($dp = opendir($dir)) { while (($file=readdir($dp)) != false) { if (is_dir($file) && $file!='.' && $file!='..') { deleteDir($file); } else { unlink($file); } } closedir($dp); } else { exit('Not permission'); } } } Copy after login 2. Depending on the system, call the delete command separately function del_dir($dir) { if(strtoupper(substr(PHP_OS, 0, 3)) == 'WIN') { $str = "rmdir /s/q " . $dir; } else { $str = "rm -Rf " . $dir; } } Copy after login 3. Circular method function deltree($pathdir) { echo $pathdir;//调试时用的 if(is_empty_dir($pathdir))//如果是空的 { rmdir($pathdir);//直接删除 } else {//否则读这个目录,除了.和..外 $d=dir($pathdir); while($a=$d->read()) { if(is_file($pathdir.'/'.$a) && ($a!='.') && ($a!='..')){unlink($pathdir.'/'.$a);} //如果是文件就直接删除 if(is_dir($pathdir.'/'.$a) && ($a!='.') && ($a!='..')) {//如果是目录 if(!is_empty_dir($pathdir.'/'.$a))//是否为空 {//如果不是,调用自身,不过是原来的路径+他下级的目录名 deltree($pathdir.'/'.$a); } if(is_empty_dir($pathdir.'/'.$a)) {//如果是空就直接删除 rmdir($pathdir.'/'.$a); } } } $d->close(); echo "必须先删除目录下的所有文件";//我调试时用的 } } function is_empty_dir($pathdir) { //判断目录是否为空 $d=opendir($pathdir); $i=0; while($a=readdir($d)) { $i++; } closedir($d); if($i>2){return false;} else return true; } Copy after login |

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.
