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

Phar::compressFiles — Compresses all files in the current Phar archive

### Beschreibung

public void Phar::compressFiles ( int `$compression` )

> Hinweis:

> Diese Methode des Phar-Objekts funktioniert nur wenn die php.ini-Einstellung phar.readonly auf 0 gesetzt ist, sonst wird eine PharException geworfen.

For tar-based phar archives, this method throws a BadMethodCallException, as compression of individual files within a tar archive is not supported by the file format. Use Phar::compress() to compress an entire tar-based phar archive.

For Zip-based and phar-based phar archives, this method compresses all files in the Phar archive using the specified compression. The zlib or bzip2 extensions must be enabled to take advantage of this feature. In addition, if any files are already compressed using bzip2/zlib compression, the respective extension must be enabled in order to decompress the files prior to re-compressing. As with all functionality that modifies the contents of a phar, the phar.readonly INI variable must be off in order to succeed.

### Parameter-Liste

`compression`

  Compression must be one of Phar::GZ, Phar::BZ2 to add compression, or Phar::NONE to remove compression.

### Rückgabewerte

Es wird kein Wert zurückgegeben.

### Fehler/Exceptions

Throws BadMethodCallException if the phar.readonly INI variable is on, the zlib extension is not available, or if any files are compressed using bzip2 compression and the bzip2 extension is not enabled.

### Beispiele

Beispiel #1 A Phar::compressFiles() example

`<?php
$p = new Phar('/path/to/my.phar', 0, 'my.phar');
$p['myfile.txt'] = 'hi';
$p['myfile2.txt'] = 'hi';
foreach ($p as $file) {
var_dump($file->getFileName());
var_dump($file->isCompressed());
var_dump($file->isCompressed(Phar::BZ2));
var_dump($file->isCompressed(Phar::GZ));
}
$p->compressFiles(Phar::GZ);
foreach ($p as $file) {
var_dump($file->getFileName());
var_dump($file->isCompressed());
var_dump($file->isCompressed(Phar::BZ2));
var_dump($file->isCompressed(Phar::GZ));
}
?>`

Das oben gezeigte Beispiel erzeugt folgende Ausgabe:

    string(10) "myfile.txt"
    bool(false)
    bool(false)
    bool(false)
    string(11) "myfile2.txt"
    bool(false)
    bool(false)
    bool(false)
    string(10) "myfile.txt"
    int(4096)
    bool(false)
    bool(true)
    string(11) "myfile2.txt"
    int(4096)
    bool(false)
    bool(true)
