Phar::buildFromDirectory

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

Phar::buildFromDirectory — Construct a phar archive from the files within a directory.

说明

public array Phar::buildFromDirectory ( string $base_dir [, string $regex ] )

Note:

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 directory contents. The optional second parameter is a regular expression (pcre) that is used to exclude files. Any filename that matches the regular expression will be included, all others will be excluded. For more fine-grained control, use Phar::buildFromIterator().

参数

base_dir

The full or relative path to the directory that contains all files to add to the archive.

regex

An optional pcre regular expression that is used to filter the list of files. Only file paths matching the regular expression will be included in the archive.

返回值

Phar::buildFromDirectory() 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 throws BadMethodCallException when unable to instantiate the internal directory iterators, or a PharException if there were errors saving the phar archive.

范例

Example #1 A Phar::buildFromDirectory() example

<?php
// create with alias "project.phar"
$phar = new Phar('project.phar', 0, 'project.phar');
// add all files in the project
$phar->buildFromDirectory(dirname(__FILE__) . '/project');
$phar->setStub($phar->createDefaultStub('cli/index.php', 'www/index.php'));

$phar2 = new Phar('project2.phar', 0, 'project2.phar');
// add all files in the project, only include php files
$phar2->buildFromDirectory(dirname(__FILE__) . '/project', '/\.php$/');
$phar2->setStub($phar->createDefaultStub('cli/index.php', 'www/index.php'));
?>

If you want to exclude a directory from the archive (but include all the other content), the regular expression must take into consideration the whole path of the file, not just the file or directory name relative to the source folder.

As an example, if we want to exclude "nbproject" directory from the archive (and any occurrence of it):

/tmp/myfolder
  /nbproject
  /something
  /something-else
    /nbproject
  /file1.php
  /file2.php

the regex should be:
<?php
  $exclude = '/^(?!(.*nbproject))(.*)$/i';  //ignoring the case
?>

A more complete example:
<?php
    $archive_file = 'myarchive.tar';
    $folder_to_compress = '/tmp/myfolder';
    $archive = new PharData($archive_file);
    $exclude = '/^(?!(.*nbproject))(.*)$/i'; 
    $archive->buildFromDirectory($folder_to_compress,$exclude);
    $archive->compress(Phar::GZ);
    unlink($archive_file); // as we already obtained a tar.gz
?>

the archive will contain:
/
  /something
  /something-else
  /file1.php
  /file2.php
