PharData::buildFromIterator — Construct a tar or zip archive from an iterator.
Описание
Populate a tar or zip archive from an iterator. Two styles of iterators are supported, iterators that map the filename within the tar/zip to the name of a file on disk, and iterators like DirectoryIterator that return SplFileInfo objects. For iterators that return SplFileInfo objects, the second parameter is required.
Примеры
Пример #1 A PharData::buildFromIterator() with SplFileInfo
For most tar/zip archives, the archive will reflect an actual directory layout, and the second style is the most useful. For instance, to create a tar/zip archive containing the files in this sample directory layout:
/path/to/project/
config/
dist.xml
debug.xml
lib/
file1.php
file2.php
src/
processthing.php
www/
index.php
cli/
index.php
This code could be used to add these files to the "project.tar" tar archive:
<?php
$phar = new PharData('project.tar');
$phar->buildFromIterator(
new RecursiveIteratorIterator(
new RecursiveDirectoryIterator('/path/to/project')),
'/path/to/project');
?>
The file project.tar can then be used immediately. buildFromIterator() does not set values such as compression, metadata, and this can be done after creating the tar/zip archive.
As an interesting note, buildFromIterator() can also be used to copy the contents of an existing phar, tar or zip archive, as the PharData object descends from DirectoryIterator:
<?php
$phar = new PharData('project.tar');
$phar->buildFromIterator(
new RecursiveIteratorIterator(
new Phar('/path/to/anotherphar.phar')),
'phar:///path/to/anotherphar.phar/path/to/project');
$phar->setStub($phar->createDefaultWebStub('cli/index.php', 'www/index.php'));
?>
Пример #2 A PharData::buildFromIterator() with other iterators
The second form of the iterator can be used with any iterator that returns a key => value mapping, such as an ArrayIterator:
<?php
$phar = new PharData('project.tar');
$phar->buildFromIterator(
new ArrayIterator(
array(
'internal/file.php' => dirname(__FILE__) . '/somefile.php',
'another/file.jpg' => fopen('/path/to/bigfile.jpg', 'rb'),
)));
?>
Список параметров
- iter
-
Any iterator that either associatively maps tar/zip file to location or returns SplFileInfo objects
- base_directory
-
For iterators that return SplFileInfo objects, the portion of each file's full path to remove when adding to the tar/zip archive
Возвращаемые значения
buildFromIterator() returns an associative array mapping internal path of file to the full path of the file on the filesystem.
Errors/Exceptions
This method returns UnexpectedValueException when the iterator returns incorrect values, such as an integer key instead of a string, a BadMethodCallException when an SplFileInfo-based iterator is passed without a base_directory parameter, or a PharException if there were errors saving the phar archive.
