Examples

Example 1. Create a Zip archive

de> <?php

$zip
= new ZipArchive();
$filename = "./test112.zip";

if (
$zip->open($filename, ZIPARCHIVE::CREATE)!==TRUE) {
    exit(
"cannot open <$filename>\n");
}

$zip->addFromString("testfilephp.txt" . time(), "#1 This is a test string added as testfilephp.txt.\n");
$zip->addFromString("testfilephp2.txt" . time(), "#2 This is a test string added as testfilephp2.txt.\n");
$zip->addFile($thisdir . "/too.php","/testfromfile.php");
echo
"numfiles: " . $zip->numFiles . "\n";
echo
"status:" . $zip->status . "\n";
$zip->close();
?>
de>

Example 2. Dump the archive details and listing

de> <?php
$za
= new ZipArchive();

$za->open('test_with_comment.zip');
print_r($za);
var_dump($za);
echo
"numFiles: " . $za->numFiles . "\n";
echo
"status: " . $za->status  . "\n";
echo
"statusSys: " . $za->statusSys . "\n";
echo
"filename: " . $za->filename . "\n";
echo
"comment: " . $za->comment . "\n";

for (
$i=0; $i<$za->numFiles;$i++) {
    echo
"index: $i\n";
    
print_r($za->statIndex($i));
}
echo
"numFile:" . $za->numFiles . "\n";
?>
de>

Example 3. Zip stream wrapper, read an OpenOffice meta info

de> <?php
$reader
= new XMLReader();

$reader->open('zip://' . dirname(__FILE__) . '/test.odt#meta.xml');
$odt_meta = array();
while (
$reader->read()) {
    if (
$reader->nodeType == XMLREADER::ELEMENT) {
        
$elm = $reader->name;
    } else {
        if (
$reader->nodeType == XMLREADER::END_ELEMENT && $reader->name == 'office:meta') {
            break;
        }
        if (!
trim($reader->value)) {
            continue;
        }
        
$odt_meta[$elm] = $reader->value;
    }
}
print_r($odt_meta);
?>
de>

This example uses the old API (PHP 4), it 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.

Example 4. Zip Usage Example

de> <?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);

}
?>
