note 102340 added to function.ziparchive-addfile

RE: aartdebruijn Note on 1024 file limit when adding files to archive.

Simple solution for creating large archives - break the file into parts during the loop.

/*
  (scalar)  $zipFile   - full path to zip file
  (scalar)  $filesPath - base path of files list
  (array)   $filesList - list of files relative to base path
*/
function create_zip( $zipFile, $filesPath, $filesList, $ignoreError=false ){
  // Max Timeout
  ini_set('max_execution_time', 300);
  // Handler
  $zip = new ZipArchive();
  // Create Archive
  if ($zip->open($zipFile, ZIPARCHIVE::CREATE) !== true) {
    return 'Failed to create archive';
  }
  // Append Files to Archive
  // Close / Open after Max to overcome server Open File Limits
  $loop_inc = 0; $loop_max = 200;
  foreach($filesList AS $fn) {
    $fp = $filesPath.$fn;
    if( file_exists($fp) && is_readable($fp) ){
      // Add file to archive
      if( $zip->addFile($fp, $fn) !== true )
        return 'Failed to add file to archive: '.$fn;
      // If Max Reached - Close / Open
      if( $loop_inc++ > $loop_max ){
        $zip->close();
        if( $zip->open( $zipFile ) !==  true ){
          return 'Failed to open archive for append';
        }
        $loop_inc = 0;
      }
    } elseif( !$ignoreError )
      return 'Failed to add file to archive: '.$fn;
  }
  // Close
  $zip->close();
  return true;
}

/* Example */
$res = create_zip(
        '/home/username/www/myfile.zip',
        '/home/username/www/images/',
        array( 'image1.jpg', 'folder/image2.jpg' )
        );
if( $res !== true ) echo 'Whoops! '.$res;
