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

$success = false;

$zip = new Zip();

// Open an existing ZIP archive.
try {
    $zip->OpenZip('c:/temp/sample.zip');
} catch (\Chilkat2\Exception $e) {
    echo $e->getMessage(), "\n";
    exit;
}

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

try {
    $zip->EntryMatching('docs/*', $entry);
    $success = true;
} catch (\Chilkat2\Exception $e) {
    $success = false;
}
if (!$success) {
    echo "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 ($success) {
    if ($entry->IsDirectory) {
        echo '[Directory] ', $entry->FileName, "\n";
    } else {
        echo '[File] ', $entry->FileName, "\n";
    }

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

$zip->CloseZip();

echo "Done.\n";
