PHP Implementation Compressed Directory Zip

First step: Create a Makezip class file

<?PHPclassmakezip{/** * Description: Main method: Generate Compressed Package * @author: MY * @param $dir _path want to compress directory: such as './demo/' * @param $zipName compression After the file name: such as './folder/demo.zip ' * @return string*/    functionZip$dir _path,$zipName)    {         $RELATIONARR=Array(            $dir _path=Array(                ' Originname ' =$dir _path, ' is_dir ' =true, ' children ' =Array()            )        ); $key=Array_keys($RELATIONARR); $val=array_values($RELATIONARR); $this->modifiyfilename ($dir _path,$RELATIONARR[$dir _path[' Children ']); $zip=Newziparchive (); //Ziparchive::create is not created        $zip->open ($zipName, Ziparchive::CREATE); $this->zipdir ($key[0], ",$zip,$val[0] [' Children ']); $zip-Close (); $this->restorefilename ($key[0],$val[0] [' Children ']); return true; }    functionZipdir ($real _path,$zip _path, &$zip,$RELATIONARR)    {        $sub _zip_path=Empty($zip _path) ? ‘‘ :$zip _path. ‘\\‘; if(Is_dir($real _path)) {            foreach($RELATIONARR  as $k=$v) {                if($v[' Is_dir ']) {//is a folder                    $zip->addemptydir ($sub _zip_path.$v[' Originname ']); $this->zipdir ($real _path. ‘\\‘ .$k,$sub _zip_path.$v[' Originname '],$zip,$v[' Children ']); } Else{//not a folder                    $zip->addfile ($real _path. ‘\\‘ .$k,$sub _zip_path.$k); $zip->deletename ($sub _zip_path.$v[' Originname ']); $zip->renamename ($sub _zip_path.$k,$sub _zip_path.$v[' Originname ']); }            }        }    }    functionModifiyfilename ($path, &$RELATIONARR)    {        if(!Is_dir($path) || !Is_array($RELATIONARR)) {            return false; }        if($DH=Opendir($path)) {            $count= 0;  while(($file=Readdir($DH)) !==false) {                if(In_array($file,Array(‘.‘, ‘..‘,NULL)))Continue;//invalid file, redo                if(Is_dir($path. ‘\\‘ .$file)) {                    $newName=MD5(Rand(0, 99999).Rand(0, 99999).Rand(0, 99999).Microtime() . ' dir '.$count); $RELATIONARR[$newName] =Array(                        ' Originname ' =Iconv(' GBK ', ' UTF-8 ',$file), ' is_dir ' =true, ' children ' =Array()                    ); Rename($path. ‘\\‘ .$file,$path. ‘\\‘ .$newName); $this->modifiyfilename ($path. ‘\\‘ .$newName,$RELATIONARR[$newName[' Children ']); $count++; } Else {                    $extension=STRCHR($file, ‘.‘); $newName=MD5(Rand(0, 99999).Rand(0, 99999).Rand(0, 99999).Microtime() . ' File '.$count); $RELATIONARR[$newName.$extension] =Array(                        ' Originname ' =Iconv(' GBK ', ' UTF-8 ',$file), ' is_dir ' =false, ' children ' =Array()                    ); Rename($path. ‘\\‘ .$file,$path. ‘\\‘ .$newName.$extension); $count++; }            }        }    }    functionRestorefilename ($path,$RELATIONARR)    {        foreach($RELATIONARR  as $k=$v) {            if(!Empty($v[' Children '])) {                $this->restorefilename ($path. ‘\\‘ .$k,$v[' Children ']); Rename($path. ‘\\‘ .$k,Iconv(' UTF-8 ', ' GBK ',$path. ‘\\‘ .$v[' Originname '])); } Else {                Rename($path. ‘\\‘ .$k,Iconv(' UTF-8 ', ' GBK ',$path. ‘\\‘ .$v[' Originname '])); }        }    }}

Step Two: Call the index.php file

<?PHP/** * The following code is implemented to compress the demo directory into a zip package and store it in the folder directory with the name Demo.zip*/include_once"./makezip.class.php";$makeZip=Newmakezip ();Try{    //repeated compression, it will automatically overwrite    $res=$makeZip->zip ('./demo/', './folder/demo.zip ')); if(!$res){        Throw New Exception(' Compression failed '); }    Echo' Success ';}Catch(Exception $e){    Echo $e-getMessage ();}
