Iterate Through Matching ZIP Entries Using EntryMatching and ZipEntry.GetNextMatch

See more Zip Examples

This example demonstrates how to iterate through ZIP entries matching a wildcard pattern using:

• Zip.EntryMatching to obtain the first matching entry
• ZipEntry.GetNextMatch to advance to subsequent matching entries

The wildcard character * matches zero or more characters. Matching is performed against the full stored ZIP entry path.

The example searches for all entries beneath the docs/ directory.

Suppose the ZIP archive contains:

docs/
docs/readme.txt
docs/manual.pdf
docs/sub1/notes.txt
images/logo.png
hello.txt

The wildcard pattern:

docs/*

Matches:

docs/
docs/readme.txt
docs/manual.pdf
docs/sub1/notes.txt

Note that ZIP archives may optionally contain separate directory entries. Therefore, the first matching entry may be the directory entry docs/ rather than a file entry.

<?php

// Open an existing ZIP archive.
$success = $zip->OpenZip('c:/temp/sample.zip');
if ($success == false) {
    print $zip->lastErrorText() . "\n";
    exit;
}

// ------------------------------------------------------------
// Find the first ZIP entry matching the wildcard pattern:
// 
//     docs/*
// 
// Matching is performed against the full stored ZIP path.
// 
$entry = new CkZipEntry();

$success = $zip->EntryMatching('docs/*',$entry);
if ($success == false) {
    print 'No matching entries found.' . "\n";
    $zip->CloseZip();
    exit;
}

// ------------------------------------------------------------
// Iterate through all matching entries.
// 
// GetNextMatch updates the same ZipEntry object so that
// it represents the next matching entry.
// 
while (($success == true)) {
    if ($entry->get_IsDirectory() == true) {
        print '[Directory] ' . $entry->fileName() . "\n";
    }
    else {
        print '[File] ' . $entry->fileName() . "\n";
    }

    // Advance to the next matching entry.
    $success = $entry->GetNextMatch('docs/*');
}

$zip->CloseZip();

print 'Done.' . "\n";
