Three ways to delete a directory using a PHP program

1. Recursive method://No Test

The following are the referenced contents: 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 Invoke method

The following are the referenced contents: function Del_dir ($dir) { if (Strtoupper (substr (php_os, 0, 3)) = = ' WIN ') { $str = "rmdir/s/q". $dir; } else { $str = "Rm-rf". $dir; } }

3. Cyclic method from webjx.com

The following are the referenced contents: function deltree ($pathdir) { echo $pathdir;//I use it when I'm debugging. if (Is_empty_dir ($pathdir))//If Empty { RmDir ($pathdir);//delete directly } Else {//otherwise read this directory, except ... and. Outside $d =dir ($pathdir); while ($a = $d->read ()) { if (Is_file ($pathdir. ') /'. $a) && ($a!= '. ') && ($a!= ' ... ')) {unlink ($pathdir. ') /'. $a);} If it's a file, delete it directly. if (Is_dir ($pathdir. ') /'. $a) && ($a!= '. ') && ($a!= ' ... ')) {//If it is a directory if (!is_empty_dir ($pathdir. ') /'. $a))/is empty {//If not, call itself, but the original path + his subordinate directory name deltree ($pathdir. ' /'. $a); } if (Is_empty_dir ($pathdir. ') /'. $a)) {//If it is empty, delete it directly RmDir ($pathdir. ' /'. $a); } } } $d->close (); echo "must first delete all files under the directory";//I use it when I debug } } function Is_empty_dir ($pathdir) { I don't think it's a good way to tell if the directory is empty. Just to see, except. Something else is not empty. $d =opendir ($pathdir); $i = 0; while ($a =readdir ($d)) { $i + +; } Closedir ($d); if ($i >2) {return false;} else return true; }
