PharData::buildFromIterator — Construct a tar or zip archive from an iterator.
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.

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. PharData::buildFromIterator() does not set values such as compression, metadata, and this can be done after creating the tar/zip archive.
As an interesting note, PharData::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->createDefaultStub('cli/index.php', 'www/index.php'));
?>
Örnek 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'),
)));
?>
iterAny iterator that either associatively maps tar/zip file to location or returns SplFileInfo objects
base_directoryFor iterators that return SplFileInfo objects, the portion of each file's full path to remove when adding to the tar/zip archive
PharData::buildFromIterator() returns an associative array mapping internal path of file to the full path of the file on the filesystem.
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.
