ZipArchive php Class - Is it built-in to PHP?
Ok, just wondering on the versions of PHP that this class is built into. And if they are built into all platforms (OS's). I'm wanting an approach to search through a zip file and place files using file_put_contents in different filepaths within the webroot. In any case, I'm familiar with how to do this with the ZipArchive class, but I'm wondering if using this class would be a good solution and support MOST, if not ALL servers?? I mean, I'd rather not use a method that requires the Server to have it installed. I'm looking for a solution to this that will support at least MOST servers without having to install the class...
Thanks :)
Also, I'd like to support opening tar.gz and/or .tgz files if possible, but I don't think the ZipArchive class supports this, but perhaps a different built-in php class does??
Answer
Tar support is not built into PHP, but if you have a look at the PEAR library you should be able to find some classes that support creating/extracting tarballs (amongst others). Have a look at http://pear.php.net/package/Archive_Tar or http://pear.php.net/package/File_Archive. The last one should be a generic interface to multiple archiving formats (including ZIP and TAR).
Whether or not ZIP support is built-in may vary, though I guess most packagers will include it. Then again, you could always test it by checking if the ZipArchive class exists by calling class_exists('ZipArchive'); and show a nice error message or fall back to a more generic approach...
