Creating a zip file with PHP's ZipArchive I recently had a requirement to create a zip file from a number of files created within my application. As it has been years since I last had this problem, I had a look around and discovered that PHP 5.2 has the ZipArchive class that makes this easy. Create Zip Archive Using PHP is very simple just like zip files and folders on your desktop. PHP Zip Class has all the inbuilt functionality you need to zip files and that is online on the web that’s the great news right!
Hi, I have a question. I looked everywhere, the doc on php.net, google, forums, but I can’t find out: How do you set the compression method (storage, fast, normal, best) with the ZipArchive class? I need to set it to the storage mode, so it just groups files together without compressing them, because those files are already compressed (jpeg, mp3) and the compression actually take some times with big files like mp3s. I do use caching (I just don’t delete the archive after submission), but the thing is the archives need to be created at least once, and it takes forever. If anyone knows, I’m interested. @ahmed: you’d have to modify the script so it checks for each file if it’s a folder with the is_dir function, then use open_dir to get all the files and add them to the array. Just make sure you test for “.” and “.” when looping through the folder so they are not added to the array. Hp Recovery Media Creator Windows 8 Download.
Oh and check for sub folders with is_dir too. A recursive function would be ideal. Then i think there is function to create folders inside zip archive. So it would definitely need a little bit of work, but it can be done. I recommend you look at the doc of is_dir, open_dir and ZipArchive::addEmptyDir on php.

Function create_zip(array $files = NULL,$destination = ”,$overwrite = false) { You can put “array” before the first parameter, this will make sure only an array can be passed into it. You can only do this for arrays and classes iirc. If I pass “hello” as the first parameter, the script will break. Hp Laserjet 1020 Download Mac.
Count(‘hello’) will return (int) 1 which, when casted to a bool be TRUE. Using the modified code above will result in the following error while passing a string value. Catchable fatal error: Argument 1 passed to create_zip() must be an array, string given. For all those here who have had an issue with nested folders inside your zip file with PC/Windows blocking extraction – I too had this issue. Eg I have modified this script to keep the nested folder structure by passing in an array of files to add with source & destination keys.
When my windows users (I’m a mac man myself) couldn’t open I started to wonder whether it was an encoding error as some of my folder names contain parentheses – not by my design but a default of Adobe’s where they export artwork files to a (Footage) folder. But I digress. The issue ended up being a dirty old slash / at the beginning of my nested folder structure. Eg /(Footage)/foo/bar After removing proceeding / eg (Footage)/foo/bar – all worked fine. Note that programs like winzip handled the opening / slash fine – just the builtin windows extractor had the issue. I hope this helps out any if at all – took me a few hours to sort.
@daniel (or anyone else getting an “empty” zip file) I too was getting zip files of the appropriate size, but appeared empty when viewed and and I tried to extract, windows was telling me the file was invalid. After looking at the ZipArchive manual on php.net, the problem stems from: $zip->addFile($file,$file); unless you have the function in the same directory as the files you want to zip, you will need to include the file path (which most people will if they use the function as an include). The 2nd parameter in addFile is the name of the file inside the zip, so if your $file var includes the path, that’s where the nested folder issue is coming from. So to solve this, I changed the code to: $just_name = preg_replace('/(.*) /?([^ /]+)/','$2',$file); $zip->addFile($file,$just_name); which will strip out the file path (if any) and leave you only the file name for the 2nd variable in addFile. Now my zips open and extract just fine = ).
