PharData::buildFromIterator — Construct a tar or zip archive from an iterator.
Description
array PharData::buildFromIterator
( Iterator $iter
[, string $base_directory
] )
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. 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'));
?>
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
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.
