简介

Rar is a powerful and effective archiver created by Eugene Roshal. This extension gives you possibility to read Rar archives but doesn't support writing Rar archives, because this is not supported by UnRar library and is directly prohibited by it's license.

例子 2. Rar extension overview example <?php $rar_file = rar_open('example.rar') or die("Can't open Rar archive"); $entries = rar_list($rar_file); foreach ($entries as $entry) {     echo 'Filename: ' . $entry->getName() . "\n";     echo 'Packed size: ' . $entry->getPackedSize() . "\n";     echo 'Unpacked size: ' . $entry->getUnpackedSize() . "\n";     $entry->extract('/dir/extract/to/'); } rar_close($rar_file); ?>
