PHP Класс CI_Zip, TastyIgniter

This class is based on a library I found at Zend: http://www.zend.com/codex.php?id=696&single=1 The original library is a little rough around the edges so I refactored it and added several additional methods -- Rick Ellis

Описание методов

__construct() публичный Метод

Initialize zip compression class
public __construct ( ) : void
Результат void

_add_data() защищенный Метод

Add Data to Zip
protected _add_data ( string $filepath, string $data, integer $file_mtime, integer $file_mdate ) : void
$filepath string the file name/path
$data string the data to be encoded
$file_mtime integer
$file_mdate integer
Результат void

_add_dir() защищенный Метод

Add Directory
protected _add_dir ( string $dir, integer $file_mtime, integer $file_mdate ) : void
$dir string the directory name
$file_mtime integer
$file_mdate integer
Результат void

_get_mod_time() защищенный Метод

If this is a newly created file/dir, we will set the time to 'now'
protected _get_mod_time ( string $dir ) : array
$dir string path to file
Результат array filemtime/filemdate

add_data() публичный Метод

Lets you add files to the archive. If the path is included in the filename it will be placed within a directory. Make sure you use add_dir() first to create the folder.
public add_data ( mixed $filepath, string $data = NULL ) : void
$filepath mixed A single filepath or an array of file => data pairs
$data string Single file contents
Результат void

add_dir() публичный Метод

Lets you add a virtual directory into which you can place files.
public add_dir ( mixed $directory ) : void
$directory mixed the directory name. Can be string or array
Результат void

archive() публичный Метод

Lets you write a file
public archive ( string $filepath ) : boolean
$filepath string the file name
Результат boolean

clear_data() публичный Метод

Lets you clear current zip data. Useful if you need to create multiple zips with different data.
public clear_data ( ) : CI_Zip
Результат CI_Zip

download() публичный Метод

Download
public download ( string $filename = 'backup.zip' ) : void
$filename string the file name
Результат void

get_zip() публичный Метод

Get the Zip file
public get_zip ( ) : string
Результат string (binary encoded)

read_dir() публичный Метод

This function recursively reads a folder and everything it contains (including sub-folders) and creates a zip based on it. Whatever directory structure is in the original file path will be recreated in the zip file.
public read_dir ( string $path, boolean $preserve_filepath = TRUE, string $root_path = NULL ) : boolean
$path string path to source directory
$preserve_filepath boolean
$root_path string
Результат boolean

read_file() публичный Метод

Read the contents of a file and add it to the zip
public read_file ( string $path, boolean $archive_filepath = FALSE ) : boolean
$path string
$archive_filepath boolean
Результат boolean
