ZipArchive::getStream — Get a file handler to the entry defined by its name (read only)

Description

public ZipArchive::getStream(string $name): resource|false

Get a file handler to the entry defined by its name. For now, it only supports read operations.

Parameters

name: The name of the entry to use.

Return Values

Returns a file pointer (resource) on success or false on failure.

Examples

Example #1 Get the entry contents with fread() and store it

<?php
$contents = '';
$z = new ZipArchive();
if ($z->open('test.zip')) {
    $fp = $z->getStream('test');
    if(!$fp) exit("failed\n");

    while (!feof($fp)) {
        $contents .= fread($fp, 2);
    }

    fclose($fp);
    file_put_contents('t',$contents);
    echo "done.\n";
}
?>

Example #2 Same as the previous example but with fopen() and the zip stream wrapper

<?php
$contents = '';
$fp = fopen('zip://' . dirname(__FILE__) . '/test.zip#test', 'r');
if (!$fp) {
    exit("cannot open\n");
}
while (!feof($fp)) {
    $contents .= fread($fp, 2);
}
echo "$contents\n";
fclose($fp);
echo "done.\n";
?>

Example #3 Stream wrapper and image, can be used with the xml function as well

<?php
$im = imagecreatefromgif('zip://' . dirname(__FILE__) . '/test_im.zip#pear_item.gif');
imagepng($im, 'a.png');
?>

Here a way to handle specific files from a zip archive without full extract :

<?php

$zip_file = '/path/to/file.zip'; // I wan to get stream a CSV files

$zip = new ZipArchive();
$zip->open($zip_file);
for ($i = 0; $i < $zip->numFiles; $i++) { // Check file by file
    $name = $zip->getNameIndex($i); // Retrieve entry name
    $extension = pathinfo($name, PATHINFO_EXTENSION);
    if ($extension === 'csv') { // I want to handle csv files
        $stream = $zip->getStream($name); // No stream index access before PHP 8.2
        // Starting PHP 8.2 $zip->getStreamIndex() or $zip->getStreamName()
        // Do stuff with $stream
        // ...
    }
}
