PharData::buildFromIterator — Construct a tar or zip archive from an iterator

Descrição

public PharData::buildFromIterator(Traversable $iterator, ?string $baseDirectory = null): array

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.

Parâmetros

iterator: Any iterator that either associatively maps tar/zip 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 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/Exceções

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.

Registro de Alterações

Versão	Descrição
8.1.0	PharData::buildFromIterator() no longer returns `false`.
8.0.0	`baseDirectory` is now nullable.

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'),
     )));
?>

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);
                }
            }
