Method Details

Archive_Tar() public method

If the compress argument is set the tar will be read or created as a gzip or bz2 compressed TAR file.
public Archive_Tar ( string $p_tarname, string $p_compress = null )
$p_tarname string The name of the tar archive to create
$p_compress string can be null, 'gz' or 'bz2'. This parameter indicates if gzip or bz2 compression is required. For compatibility reason the boolean value 'true' means 'gz'.

add() public method

The method return false and a PEAR error text. The files and directories listed are only added at the end of the archive, even if a file with the same name is already archived. See also createModify() method for more details.
See also: createModify()
public add ( array $p_filelist ) : true
$p_filelist array An array of filenames and directory names, or a single string with names separated by a single blank space.
return true on success, false on error.

addModify() public method

The $p_filelist parameter can be an array of string, each string representing a filename or a directory name with their path if needed. It can also be a single string with names separated by a single blank. The path indicated in $p_remove_dir will be removed from the memorized path of each file / directory listed when this path exists. By default nothing is removed (empty path '') The path indicated in $p_add_dir will be added at the beginning of the memorized path of each file / directory listed. However it can be set to empty ''. The adding of a path is done after the removing of path. The path add/remove ability enables the user to prepare an archive for extraction in a different path than the origin files are. If a file/dir is already in the archive it will only be added at the end of the archive. There is no update of the existing archived file/dir. However while extracting the archive, the last file will replace the first one. This results in a none optimization of the archive size. If a file/dir does not exist the file/dir is ignored. However an error text is send to PEAR error. If a file/dir is not readable the file/dir is ignored. However an error text is send to PEAR error.
public addModify ( array $p_filelist, string $p_add_dir, string $p_remove_dir = '' ) : true
$p_filelist array An array of filenames and directory names, or a single string with names separated by a single blank space.
$p_add_dir string A string which contains a path to be added to the memorized path of each element in the list.
$p_remove_dir string A string which contains a path to be removed from the memorized path of each element in the list, when relevant.
return true on success, false on error.

addString() public method

This method add a single string as a file at the end of the existing archive. If the archive does not yet exists it is created.
public addString ( string $p_filename, string $p_string ) : true
$p_filename string A string which contains the full filename path that will be associated with the string.
$p_string string The content of the file added in the archive.
return true on success, false on error.

create() public method

If a file with the same name exist and is writable, it is replaced by the new tar. The method return false and a PEAR error text. The $p_filelist parameter can be an array of string, each string representing a filename or a directory name with their path if needed. It can also be a single string with names separated by a single blank. For each directory added in the archive, the files and sub-directories are also added. See also createModify() method for more details.
See also: createModify()
public create ( array $p_filelist ) : true
$p_filelist array An array of filenames and directory names, or a single string with names separated by a single blank space.
return true on success, false on error.

createModify() public method

If the file already exists and is writable, it is replaced by the new tar. It is a create and not an add. If the file exists and is read-only or is a directory it is not replaced. The method return false and a PEAR error text. The $p_filelist parameter can be an array of string, each string representing a filename or a directory name with their path if needed. It can also be a single string with names separated by a single blank. The path indicated in $p_remove_dir will be removed from the memorized path of each file / directory listed when this path exists. By default nothing is removed (empty path '') The path indicated in $p_add_dir will be added at the beginning of the memorized path of each file / directory listed. However it can be set to empty ''. The adding of a path is done after the removing of path. The path add/remove ability enables the user to prepare an archive for extraction in a different path than the origin files are. See also addModify() method for file adding properties.
See also: addModify()
public createModify ( array $p_filelist, string $p_add_dir, string $p_remove_dir = '' ) : boolean
$p_filelist array An array of filenames and directory names, or a single string with names separated by a single blank space.
$p_add_dir string A string which contains a path to be added to the memorized path of each element in the list.
$p_remove_dir string A string which contains a path to be removed from the memorized path of each element in the list, when relevant.
return boolean true on success, false on error.

extract() public method

{{{ extract()
public extract ( $p_path = '' )

extractInString() public method

The return value is a string with the file content, or NULL on error.
public extractInString ( string $p_filename ) : a
$p_filename string The path of the file to extract in a string.
return a string with the file content or NULL.

extractList() public method

If indicated the $p_remove_path can be used in the same way as it is used in extractModify() method.
See also: extractModify()
public extractList ( array $p_filelist, string $p_path = '', string $p_remove_path = '' ) : true
$p_filelist array An array of filenames and directory names, or a single string with names separated by a single blank space.
$p_path string The path of the directory where the files/dir need to by extracted.
$p_remove_path string Part of the memorized path that can be removed if present at the beginning of the file/dir path.
return true on success, false on error.

extractModify() public method

While extracting a file, if the directory path does not exists it is created. While extracting a file, if the file already exists it is replaced without looking for last modification date. While extracting a file, if the file already exists and is write protected, the extraction is aborted. While extracting a file, if a directory with the same name already exists, the extraction is aborted. While extracting a directory, if a file with the same name already exists, the extraction is aborted. While extracting a file/directory if the destination directory exist and is write protected, or does not exist but can not be created, the extraction is aborted. If after extraction an extracted file does not show the correct stored file size, the extraction is aborted. When the extraction is aborted, a PEAR error text is set and false is returned. However the result can be a partial extraction that may need to be manually cleaned.
See also: extractList()
public extractModify ( string $p_path, string $p_remove_path ) : boolean
$p_path string The path of the directory where the files/dir need to by extracted.
$p_remove_path string Part of the memorized path that can be removed if present at the beginning of the file/dir path.
