PharData::buildFromIterator

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

PharData::buildFromIteratorConstruct a tar or zip archive from an iterator.

Descrição

array PharData::buildFromIterator ( Iterator $iter [, string $base_directory ] )

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.

Exemplos

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'));
?>

Exemplo #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'),
     )));
?>

Parâmetros

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

Valor Retornado

PharData::buildFromIterator() returns an associative array mapping internal path of file to the full path of the file on the filesystem.

Erros

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.

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);
                }
            }
