Phar::buildFromIterator
(PHP 5 >= 5.3.0, PHP 7, PHP 8, PECL phar >= 2.0.0)
Phar::buildFromIterator — Construct a phar archive from an iterator
说明
注意:
此方法需要 将 php.ini 中的
phar.readonly设为0以适合 Phar 对象. 否则, 将抛出PharException.
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.
参数
iterator- 
      
Any iterator that either associatively maps phar file to location or returns SplFileInfo objects
 baseDirectory- 
      
For iterators that return SplFileInfo objects, the portion of each file's full path to remove when adding to the phar archive
 
返回值
Phar::buildFromIterator() returns an associative array mapping internal path of file to the full path of the file on the filesystem.
错误/异常
   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 baseDirectory
   parameter, or a PharException if there were errors
   saving the phar archive.

示例
示例 #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->createDefaultStub('cli/index.php', 'www/index.php'));
?>The file project.phar can then be used immediately. Phar::buildFromIterator() does not set values such as compression, metadata, and this can be done after creating the phar archive.
As an interesting note, Phar::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->createDefaultStub('cli/index.php', 'www/index.php'));
?>示例 #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->createDefaultStub('cli/index.php', 'www/index.php'));

You have to set a flag on the RecursiveDirectoryIterator because by default, the current (".") and parent directory ("..") are included in the listing. This leads to an error message similar to "returned a path ".." that is not in the base directory".
To fix this, use "SKIP_DOTS":
<?php
new RecursiveDirectoryIterator(
$srcRoot, FilesystemIterator::SKIP_DOTS
);
