note 69407 added to ref.zip

1) A warning to all users of PHP Zipping/Unzipping Classes: most of them require the whole content of the ZIP file and/or the unzipped contents to stay in memory. They work very well, but might fail with very large files. Keep this in mind before starting development of a project involving large ZIP files. 2) If all you need is to unzip files to a folder, and your server has a zip command line tool, all you might need is a function like this: if(!defined('UNZIP_CMD')) define('UNZIP_CMD','unzip -o @_SRC_@ -x -d @_DST_@'); function UnzipAllFiles($zipFile,$zipDir) { $unzipCmd=UNZIP_CMD; $unzipCmd=str_replace('@_SRC_@',$zipFile,$unzipCmd); $unzipCmd=str_replace('@_DST_@',$zipDir,$unzipCmd); $res=-1; // any nonzero value $UnusedArrayResult=array(); $UnusedStringResult=exec($unzipCmd,$UnusedArrayResult,$res); return ($res==0); } // * * * You DO NOT NEED the ZIP lib or M-ZIP to use this, but you will need the tool M-ZIP uses (unzip.exe or unzip for linux). * * * // Use it this way: $zipFile='/path/to/uploaded_file.zip'; $whereToUnzip='/path/to/writable/folder/'; $result=UnzipAllFiles($zipFile,$whereToUnzip); if($result===FALSE) echo('FAILED'); else echo('SUCCESS'); By changing UNZIP_CMD (the same constant as in the m-zip lib) you can of course untar, unarc, unrar, etc... provided you have the correct unwhatever command or unwhatever.exe executable and write its correct syntax in UNZIP_CMD. To see details of what tools you need and where to put them (or to use a syntax compatible to the standard zip lib) see http://eSurfers.com/m-zip/ ---- Server IP: 66.163.161.117 Probable Submitter: 213.156.52.105 ---- Manual Page -- http://www.php.net/manual/en/ref.zip.php Edit -- https://master.php.net/note/edit/69407 Del: integrated -- https://master.php.net/note/delete/69407/integrated Del: useless -- https://master.php.net/note/delete/69407/useless Del: bad code -- https://master.php.net/note/delete/69407/bad+code Del: spam -- https://master.php.net/note/delete/69407/spam Del: non-english -- https://master.php.net/note/delete/69407/non-english Del: in docs -- https://master.php.net/note/delete/69407/in+docs Del: other reasons-- https://master.php.net/note/delete/69407 Reject -- https://master.php.net/note/reject/69407 Search -- https://master.php.net/manage/user-notes.php
