# CXXII. Zip File Functions (Read Only Access)

# Introdução

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

# Requisitos

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.

# Instalação

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.

> Nota: 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.

# Configuração durante execução

Esta extensão não define nenhum parâmetro de configuração no `php.ini`.

# Tipos Resource

Esta extensão não possui nenhum tipo resource.

# Constantes Predefinidas

Esta extensão não possui nenhuma constante.

# Exemplos

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.

Exemplo 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);
}
?>`
