This article mainly introduces several methods of deleting directories under PHP, as follows
1. Delivery regulations
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'); } } }
2. System call method
function del_dir($dir) { if(strtoupper(substr(PHP_OS, 0, 3)) == 'WIN') { $str = "rmdir /s/q " . $dir; } else { $str = "rm -Rf " . $dir; } }
3. Cycle Method
function deltree($pathdir) { echo $pathdir;//我调试时用的 if(is_empty_dir($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,我的方法不是很好吧?只是看除了.和..之外有其他东西不是为空 $d=opendir($pathdir); $i=0; while($a=readdir($d)) { $i++; } closedir($d); if($i>2){return false;} else return true; }

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
