Phar::buildFromIterator()

(PHP 5 >= 5.3.0, PHP 7, PECL phar >= 2.0.0)

Construct a phar archive from an iterator

说明

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

Any iterator that either associatively maps phar file to location or returns SplFileInfo objects

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.

范例

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:

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:

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:

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$base_directoryparameter, or a PharException if there were errors saving the phar archive.

• Phar::buildFromDirectory() Construct a phar archive from the files within a directory

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": 

Phars created from iterator (unlike from directory) does not have full-fledged directory structure. For example, functions like opendir() will fail, although fopen() does not.
