PHP implementation zip compressed file decompression

The test uses two methods to achieve:

First: Need to turn on configuration Php_aip.dll

1<?PHP2 //need to turn on configuration Php_zip.dll3 //phpinfo ();4 Header("Content-type:text/html;charset=utf-8");5 6 functionGet_zip_originalsize ($filename,$path) {7   //determine if the file you want to unzip is present8   if(!file_exists($filename)){9      die(The file$filenamedoes not exist! ");Ten   } One   $starttime=Explode(‘ ‘,Microtime());//the time the decompression started A  - //Change the file name and path to the default gb2312 encoding of Windows system, otherwise you will not be read -   $filename=Iconv("Utf-8", "gb2312",$filename); the   $path=Iconv("Utf-8", "gb2312",$path); -   //opening a compressed package -   $resource= Zip_open ($filename); -   $i= 1; +   //iterate through the files in the compressed package -    while($dir _resource= Zip_read ($resource)) { +     //If you can open it, continue . A     if(Zip_entry_open ($resource,$dir _resource)) { at       //gets the name of the current project, which is the current file name in the compressed package -       $file _name=$path. Zip_entry_name ($dir _resource); -       //split the Last "/" and then use the string to intercept the path part -       $file _path=substr($file _name, 0,Strrpos($file _name, "/")); -       //if the path does not exist, a directory is created and True indicates that a multilevel directory can be created -       if(!Is_dir($file _path)){ in         mkdir($file _path, 0777,true); -       } to       //if it is not a directory, write the file +       if(!Is_dir($file _name)){ -         //Read this file the         $file _size= Zip_entry_filesize ($dir _resource); *         //Max Read 6M, if file is too large, skip unzip, continue next $         if($file _size< (1024*1024*30)){Panax Notoginseng           $file _content= Zip_entry_read ($dir _resource,$file _size); -           file_put_contents($file _name,$file _content); the}Else{ +           Echo"<p>".$i+ +. "This file has been skipped because: file is too large,".Iconv("gb2312", "Utf-8",$file _name). "</p>"; A         } the       } +       //Close the current -Zip_entry_close ($dir _resource); $     } $   } -   //To close a compressed package -Zip_close ($resource); the   $endtime=Explode(‘ ‘,Microtime());//time of Decompression end -   $thistime=$endtime[0]+$endtime[1]-($starttime[0]+$starttime[1]);Wuyi   $thistime=round($thistime, 3);//Keep 3 as decimal the   Echo"<p> decompression complete! , this decompression cost:$thistimeSeconds. </p> "; - } Wu  - $size= Get_zip_originalsize ('.. /.. /textaa.zip ', '. /.. /ffff/');

In the above method: $filename: File name, is the name of the file to extract, including the path relative to the method, $path means: Extract to (what directory, to/end)

The second method is to use the Pclzip class, the first method that is used in the project process because of the path problem

<?PHP/*php extracts files from zip compressed files*/$zip=Newziparchive;if($zip->open (' test.zip ') = = =TRUE) {//to use ANSI-encoded file formats for Chinese filenames  $zip->extractto (' foldername ');//extract all files//$zip->extractto ('/my/destination/dir/', Array (' pear_item.gif ', ' testfromfile.php '));//extract some files  $zip-Close (); Echo' OK ';} Else {  Echo' Failed ';}
