HomePHP Page 5 - TAR File Management With PHP Archive_Tar
Building An Index - PHP
Need to create or manipulate a TAR file through your Web browser? Take a look at the PEAR Archive_Tar class, which exposes a simple, yet extremely powerful, API to perform manipulation of TAR and TGZ archives through a PHP script. Possible applications include a TAR file viewer and a Web-based backup utility.
You can obtain a list of all the files in a TAR archive with the Archive_Tar object's listContents() method, which returns an array of arrays containing detailed information on the contents of the archive. Each element of the returned array represents a file in the source archive, each element is itself structured as an associative array of key-value pairs containing details on the file name and path (key "filename"), size ("size"), owner and group ID ("uid" and "gid"), permissions ("fileperms"), last modification time ("mtime") and whether the entry is a file or directory ("type").
Consider the following example, which demonstrates by using the listContents() method to obtain a list of all the files within a TAR file, together with their size and last modification times:
// include class
// create tar file
$tar = new Archive_Tar("data.tar");
// read and print tar file contents
if (($arr = $tar->listContent()) != 0)
foreach ($arr as $a)
echo $a['filename'] . ", " . $a['size'] . " bytes, last modified
on " . date("Y-m-d", $a['mtime']) . "\r\n";
Here's an example of the output:
