Phar::buildFromIterator — Construct a phar archive from an iterator.
Description
array Phar::buildFromIterator
( Iterator $iter
[, string $base_directory
] )
Note: This
method requires the php.ini setting phar.readonly to be
set to 0 in order to work for Phar
objects. Otherwise, a PharException will be thrown.
Populate a phar archive from an iterator. Two styles of iterators are supported,
iterators that map the filename within the phar 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 Phar::buildFromIterator() with SplFileInfo
For most phar archives, the archive will reflect an actual directory layout, and
the second style is the most useful. For instance, to create a phar 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.phar" phar archive:
<?php
// create with alias "project.phar"
$phar = new Phar('project.phar', 0, 'project.phar');
$phar->buildFromIterator(
new RecursiveIteratorIterator(
new RecursiveDirectoryIterator('/path/to/project')),
'/path/to/project');
$phar->setStub($phar->createDefaultWebStub('cli/index.php', 'www/index.php'));
?>
The file project.phar can then be used immediately. buildFromIterator() does not
set values such as compression, metadata, and this can be done after creating the
phar archive.
As an interesting note, buildFromIterator() can also be used to
copy the contents of an existing phar archive, as the Phar object descends
from DirectoryIterator:
<?php
// create with alias "project.phar"
$phar = new Phar('project.phar', 0, 'project.phar');
$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 Phar::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
// create with alias "project.phar"
$phar = new Phar('project.phar', 0, 'project.phar');
$phar->buildFromIterator(
new ArrayIterator(
array(
'internal/file.php' => dirname(__FILE__) . '/somefile.php',
'another/file.jpg' => fopen('/path/to/bigfile.jpg', 'rb'),
)));
$phar->setStub($phar->createDefaultWebStub('cli/index.php', 'www/index.php'));
?>
Parameters
-
iter
-
Any iterator that either associatively maps phar 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 phar 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.
