PharData::buildFromIterator
(PHP >= 5.3.0, PECL phar >= 2.0.0)
PharData::buildFromIterator — Construct a tar or zip archive from an iterator.
Description
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.
Examples
Example #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. 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'));
?>
Example #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'),
)));
?>
Parameters
-
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
Return Values
PharData::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.

Коментарии
The code in the first exemple doesn't work properly without the flag FilesystemIterator::SKIP_DOTS in the RecursiveDirectoryIterator (on a linux filesystem).
So, to build a tar with a phar, I do (with two level of iteration here) :
$pharTar = new \PharData($contentTar.".tar");
$firstLevelIterator = new \DirectoryIterator($this->inputPath);
foreach ($firstLevelIterator as $fileInfo) {
/* @var \SplFileInfo $fileInfo */
if (in_array($fileInfo->getFilename(), $allowedDirectory)) {
$recursiveDirectoryIterator = new \RecursiveDirectoryIterator(
$this->inputPath . DIRECTORY_SEPARATOR . $fileInfo->getFilename(), \FilesystemIterator::SKIP_DOTS);
$pharTar->buildFromIterator(new \RecursiveIteratorIterator($recursiveDirectoryIterator), $this->inputPath);
}
}
