Full documentation about PclZip can be found here : http://www.phpconcept.net/pclzip 2 - What's new ============== Version 2.3 : - Correct a bug with PHP5 : affecting the value 0xFE49FFE0 to a variable does not give the same result in PHP4 and PHP5 .... Version 2.2 : - Try development of PCLZIP_OPT_CRYPT ..... However this becomes to a stop. To crypt/decrypt I need to multiply 2 long integers, the result (greater than a long) is not supported by PHP. Even the use of bcmath functions does not help. I did not find yet a solution ...; - Add missing '/' at end of directory entries - Check is a file is encrypted or not. Returns status 'unsupported_encryption' and/or error code PCLZIP_ERR_UNSUPPORTED_ENCRYPTION. - Corrected : Bad "version need to extract" field in local file header - Add private method privCheckFileHeaders() in order to check local and central file headers. PclZip is now supporting purpose bit flag bit 3. Purpose bit flag bit 3 gives the ability to have a local file header without size, compressed size and crc filled. - Add a generic status 'error' for file status - Add control of compression type. PclZip only support deflate compression method. Before v2.2, PclZip does not check the compression method used in an archive while extracting. With v2.2 PclZip returns a new error status for a file using an unsupported compression method. New status is "unsupported_compression". New error code is PCLZIP_ERR_UNSUPPORTED_COMPRESSION. - Add optional attribute PCLZIP_OPT_STOP_ON_ERROR. This will stop the extract of files when errors like 'a folder with same name exists' or 'a newer file exists' or 'a write protected file' exists, rather than set a status for the concerning file and resume the extract of the zip. - Add optional attribute PCLZIP_OPT_REPLACE_NEWER. This will force, during an extract' the replacement of the file, even if a newer version of the file exists. Note that today if a file with the same name already exists but is older it will be replaced by the extracted one. - Improve PclZipUtilOption() - Support of zip archive with trailing bytes. Before 2.2, PclZip checks that the central directory structure is the last data in the archive. Crypt encryption/decryption of zip archive put trailing 0 bytes after decryption. PclZip is now supporting this. Version 2.1 : - Add the ability to abort the extraction by using a user callback function. The user can now return the value '2' in its callback which indicates to stop the extraction. For a pre call-back extract is stopped before the extration of the current file. For a post call back, the extraction is stopped after. - Add the ability to extract a file (or several files) directly in the standard output. This is done by the new parameter PCLZIP_OPT_EXTRACT_IN_OUTPUT with method extract(). - Add support for parameters PCLZIP_OPT_COMMENT, PCLZIP_OPT_ADD_COMMENT, PCLZIP_OPT_PREPEND_COMMENT. This will create, replace, add, or prepend comments in the zip archive. - When merging two archives, the comments are not any more lost, but merged, with a blank space separator. - Corrected bug : Files are not deleted when all files are asked to be deleted. - Corrected bug : Folders with name '0' made PclZip to abort the create or add feature. Version 2.0 : ***** Warning : Some new features may break the backward compatibility for your scripts. Please carefully read the readme file. - Add the ability to delete by Index, name and regular expression. This feature is performed by the method delete(), which uses the optional parameters PCLZIP_OPT_BY_INDEX, PCLZIP_OPT_BY_NAME, PCLZIP_OPT_BY_EREG or PCLZIP_OPT_BY_PREG. - Add the ability to extract by regular expression. To extract by regexp you must use the method extract(), with the option PCLZIP_OPT_BY_EREG or PCLZIP_OPT_BY_PREG (depending if you want to use ereg() or preg_match() syntax) followed by the regular expression pattern. - Add the ability to extract by index, directly with the extract() method. This is a code improvment of the extractByIndex() method. - Add the ability to extract by name. To extract by name you must use the method extract(), with the option PCLZIP_OPT_BY_NAME followed by the filename to extract or an array of filenames to extract. To extract all a folder, use the folder name rather than the filename with a '/' at the end. - Add the ability to add files without compression. This is done with a new attribute which is PCLZIP_OPT_NO_COMPRESSION. - Add the attribute PCLZIP_OPT_EXTRACT_AS_STRING, which allow to extract a file directly in a string without using any file (or temporary file). - Add constant PCLZIP_SEPARATOR for static configuration of filename separators in a single string. The default separator is now a comma (,) and not any more a blank space. THIS BREAK THE BACKWARD COMPATIBILITY : Please check if this may have an impact with your script. - Improve algorythm performance by removing the use of temporary files when adding or extracting files in an archive. - Add (correct) detection of empty filename zipping. This can occurs when the removed path is the same as a zipped dir. The dir is not zipped (['status'] = filtered), only its content. - Add better support for windows paths (thanks for help from manus@manusfreedom.com). - Corrected bug : When the archive file already exists with size=0, the add() method fails. Corrected in 2.0. - Remove the use of OS_WINDOWS constant. Use php_uname() function rather. - Control the order of index ranges in extract by index feature. - Change the internal management of folders (better handling of internal flag). Version 1.3 : - Removing the double include check. This is now done by include_once() and require_once() PHP directives. - Changing the error handling mecanism : Remove the use of an external error library. The former PclError...() functions are replaced by internal equivalent methods. By changing the environment variable PCLZIP_ERROR_EXTERNAL you can still use the former library. Introducing the use of constants for error codes rather than integer values. This will help in futur improvment. Introduction of error handling functions like errorCode(), errorName() and errorInfo(). - Remove the deprecated use of calling function with arguments passed by reference. - Add the calling of extract(), extractByIndex(), create() and add() functions with variable options rather than fixed arguments. - Add the ability to remove all the file path while extracting or adding, without any need to specify the path to remove. This is available for extract(), extra
