∟Exact Files from ZIP Archive

This section provides a tutorial example on how to open an existing ZIP archive and extract files from the archive using the ZipArchive class.

The easiest way to extract files from an ZIP archive to use the $zip->extractTo() method. For example, the following code extracts 'dot.gif' from '/tmp/test.zip' into the '/tmp' directory.

$zip = new ZipArchive;
$zip->open('/tmp/test.zip');
$zip->extractTo('/tmp','dot.gif');

Here is an example script that opens an existing ZIP archive and extracts files from the archive.

<?php
#  zip-extract-file.php
#- Copyright 2009 (c) HerongYang.com. All Rights Reserved.

  $zip = new ZipArchive;
  echo "Opening test.zip:\n";
  $rc = $zip->open('/tmp/test.zip',ZipArchive::CREATE);
  if ($rc === TRUE) {
    echo "   test.zip opened\n";

    $file = 'dot.gif';
    if ($zip->extractTo('.', $file) === TRUE) {
      echo "   $file extracted\n";
    } else {
      echo "   Failed to extract $file.\n";
    }

    mkdir('./tmp');
    if ($zip->extractTo('./tmp') === TRUE) {
      echo "   All files extracted\n";
    } else {
      echo "   Failed to extract all files.\n";
    }

    $zip->close();
  } else {
    echo "   Failed to open test.zip with error: $rc\n";
  }
?>

Let's try it:

herong$ php zip-extract-file.php
Opening test.zip:
test.zip opened
dot.gif extracted
All files extracted

herong$ ls -l tmp
