Extracting zipped file in cakephp

Everyone is familiar with extraction of zip files.Here iam explaining about extracting zip files in php. for this we need a library file called PCLZIP.  below is the code copy it and place in a file named PclZip.php and put it in /app/model

// Attributes :
// Attributes must not be accessed directly.
// Methods :
// PclZip() : Object creator
// create() : Creates the Zip archive
// listContent() : List the content of the Zip archive
// extract() : Extract the content of the archive

// Function : PclZip()
// Description :

// Note that no real action is taken, if the archive does not exist it is not
// created. Use create() for that.

// When a directory is in the list, the directory and its content is added
// in the archive.
// In this synopsis, the function takes an optional variable list of
// options. See bellow the supported options.

// $p_filelist : An array containing file or directory names, or
// a string containing one filename or one directory name, or
// a string containing a list of filenames and/or directory
// names separated by spaces.
// $p_add_dir : A path to add before the real path of the archived file,
// in order to have it memorized in the archive.
// $p_remove_dir : A path to remove from the real path of the file to archive,
// in order to have a shorter path memorized in the archive.
// When $p_add_dir and $p_remove_dir are set, $p_remove_dir
// is removed first, before $p_add_dir is added.

// comment : Comment associated with the file
// folder : true | false
// index : index of the file in the archive
// status : status of the action (depending of the action) :
// Values are :
// ok : OK !
// filtered : the file / dir is not extracted (filtered by user)
// already_a_directory : the file can not be extracted because a
// directory with the same name already exists
// write_protected : the file can not be extracted because a file
// with the same name already exists and is
// write protected
// newer_exist : the file was not extracted because a newer file exists
// path_creation_fail : the file is not extracted because the folder
// does not exists and can not be created
