PHP implementation recursive loop each directory program _php tutorial

To traverse all the directories in a folder, list all the files inside, PHP itself has a readdir function, but only the current directory, according to this function, I wrote another function to achieve my needs.

The code is as follows

Copy Code

Class listdir{ var $depth; var $dirname; var $list; var $tostring; function Listdir ($dir) { $this->dirname= $dir; $this->depth=0; $this->tostring= ""; } Save the result in a multidimensional array function getlist ($dir = "") { if ($dir = = "") $dir = $this->dirname; $d = @dir ($dir); while (false!== ($item = $d->read ())) { if ($item! = "." && $item! = "...") { $path = $dir. " /". $item; if (Is_dir ($path)) { $this->depth+=1; $this->getlist ($path); }else{ $this->list[$this->depth][]= $item; } } } $this->list[$this->depth][' directory ']= $dir; $this->depth-=1; $d->close (); return $this->list; } Character channeling results function ToString ($dir = "") { if ($dir = = "") $dir = $this->dirname; $d = @dir ($dir); $this->tostring.= " n "; $this->tostring.= "Directory:" $dir. " n "; while (false!== ($item = $d->read ())) { if ($item! = "." && $item! = "...") { $path = $dir. " /". $item; if (Is_dir ($path)) { $this->depth+=1; $this->tostring ($path); }else{ $this->tostring.= " ". $item." n "; } } } $this->depth-=1; $d->close (); $this->tostring.= " n "; return $this->tostring; } } $wapdir = "jquery"; $d =new Listdir ($wapdir); echo $d->tostring (); ?>

To delete an empty directory is simple ~ a

RmDir () function can be done, but to delete a non-empty directory, you will not be able to quickly delete, you must first delete the directory files, but there may be subdirectories in the directory so to be recursive delete ~ here is my example ~

The code is as follows

Copy Code

<? Php function Deletedir ($dir) { if (!handle= @opendir ($dir)) {//detects if the directory to open exists Die ("No such directory"); } while (False!== ($file =readdir ($handle))) { if ($file!== "." && $file!== "..") {//Exclude current directory from parent directory $file = $dir. Directory_separator. $file; if (Is_dir ($file)) { Deletedir ($file); }else{ if (@unlink ($file)) { echo "File $file deleted successfully. "; }else{ echo "File $file Delete failed! "; } } } if (@rmdir ($dir)) { echo "Directory $dir deleted successfully. n "; }else{ echo "Directory $dir Delete failed! n "; } } Test program $dir = "/var/www/test"; Deletedir ($dir); ？ >
