# CXXVII.Zip File Functions (Read Only Access)

# 介紹

This module enables you to transparently read ZIP compressed archives and the files inside them.

# 需求

This module uses the functions of the ZZIPlib library by Guido Draheim. You need ZZIPlib version >= 0.10.6.

Note that ZZIPlib only provides a subset of functions provided in a full implementation of the ZIP compression algorithm and can only read ZIP file archives. A normal ZIP utility is needed to create the ZIP file archives read by this library.

# 安裝

Zip support in PHP is not enabled by default. You will need to use the --with-zip[=DIR] configuration option when compiling PHP to enable zip support.

> 備注: Zip support before PHP 4.1.0 is experimental. This section reflects the Zip extension as it exists in PHP 4.1.0 and later.

# 範例

This example opens a ZIP file archive, reads each file in the archive and prints out its contents. The `test2.zip` archive used in this example is one of the test archives in the ZZIPlib source distribution.

示範 1.Zip Usage Example
`<?php $zip = zip_open("/tmp/test2.zip"); if ($zip) { while ($zip_entry = zip_read($zip)) { echo "Name: " . zip_entry_name($zip_entry) . "\n"; echo "Actual Filesize: " . zip_entry_filesize($zip_entry) . "\n"; echo "Compressed Size: " . zip_entry_compressedsize($zip_entry) . "\n"; echo "Compression Method: " . zip_entry_compressionmethod($zip_entry) . "\n"; if (zip_entry_open($zip, $zip_entry, "r")) { echo "File Contents:\n"; $buf = zip_entry_read($zip_entry, zip_entry_filesize($zip_entry)); echo "$buf\n"; zip_entry_close($zip_entry); } echo "\n"; } zip_close($zip); } ?>`
