PHP ZipArchive没有添加任何文件（Windows）

Question

I'm failing to put even a single file into a new zip archive.

makeZipTest.php:

<?php

$destination = __DIR__.'/makeZipTest.zip';
$fileToZip = __DIR__.'/hello.txt';

$zip = new ZipArchive();
if (true !== $zip->open($destination, ZIPARCHIVE::OVERWRITE)) {
    die("Problem opening zip $destination");
}
if (!$zip->addFile($fileToZip)) {
    die("Could not add file $fileToZip");
}
echo "numfiles: " . $zip->numFiles . "\n";
echo "status: " . $zip->status . "\n";
$zip->close();

The zip gets created, but is empty. Yet no errors are triggered.

What is going wrong?

Answer 1

It seems on some configuration, PHP fails to get the localname properly when adding files to a zip archive and this information must be supplied manually. It is therefore possible that using the second parameter of addFile() might solve this issue.

ZipArchive::addFile

Parameters

• filename
  The path to the file to add.
• localname
  If supplied, this is the local name inside the ZIP archive that will override the filename.

PHP documentation: ZipArchive::addFile

$zip->addFile(
    $fileToZip, 
    basename($fileToZip)
);

You may have to adapt the code to get the right tree structure since basename() will remove everything from the path apart from the filename.

You need to give server right permission in folder where they create zip archive. You can create tmp folder with write permision chmod 777 -R tmp/

Also need to change destination where script try to find hello.txt file $zip->addFile($fileToZip, basename($fileToZip))

<?php

$destination = __DIR__.'/tmp/makeZipTest.zip';
$fileToZip = __DIR__.'/hello.txt';

$zip = new ZipArchive();
if (true !== $zip->open($destination, ZipArchive::OVERWRITE)) {
  die("Problem opening zip $destination");
}
if (!$zip->addFile($fileToZip, basename($fileToZip))) {
  die("Could not add file $fileToZip");
}
echo "numfiles: " . $zip->numFiles . "\n";
echo "status: " . $zip->status . "\n";
$zip->close()

check this class to add files and sub-directories in a folder to zip file,and also check the folder permissions before running the code, ie chmod 777 -R zipdir/

HZip::zipDir('/path/to/sourceDir', '/path/to/out.zip'); 

<?php 
class HZip 
{ 

private static function folderToZip($folder, &$zipFile, $exclusiveLength) { 
$handle = opendir($folder); 
while (false !== $f = readdir($handle)) { 
  if ($f != '.' && $f != '..') { 
    $filePath = "$folder/$f"; 
    // Remove prefix from file path before add to zip. 
    $localPath = substr($filePath, $exclusiveLength); 
    if (is_file($filePath)) { 
      $zipFile->addFile($filePath, $localPath); 
    } elseif (is_dir($filePath)) { 
      // Add sub-directory. 
      $zipFile->addEmptyDir($localPath); 
      self::folderToZip($filePath, $zipFile, $exclusiveLength); 
    } 
  } 
} 
closedir($handle); 
} 


public static function zipDir($sourcePath, $outZipPath) 
{ 
$pathInfo = pathInfo($sourcePath); 
$parentPath = $pathInfo['dirname']; 
$dirName = $pathInfo['basename']; 

$z = new ZipArchive(); 
$z->open($outZipPath, ZIPARCHIVE::CREATE); 
$z->addEmptyDir($dirName); 
self::folderToZip($sourcePath, $z, strlen("$parentPath/")); 
$z->close(); 
} 
}
