(PHP >= 5.3.0, PECL phar >= 1.0.0)
Phar::compressAllFilesBZIP2 — Compresses all files in the current Phar archive using Bzip2 compression
Note: This method has been removed from the phar extension as of version 2.0.0. Alternative implementations are available using Phar::compress(), Phar::decompress(), Phar::compressFiles() and Phar::decompressFiles().
Note: This method requires the php.ini setting phar.readonly to be set to 0 in order to work for Phar objects. Otherwise, a PharException will be thrown.
This method compresses all files in the Phar archive using bzip2 compression. The bzip2 extension must be enabled to take advantage of this feature. In addition, if any files are already compressed using gzip compression, the zlib extension must be enabled in order to decompress the files prior to re-compressing with bzip2 compression. As with all functionality that modifies the contents of a phar, the phar.readonly INI variable must be off in order to succeed.
Throws BadMethodCallException if the phar.readonly INI variable is on, the bzip2 extension is not available, or if any files are compressed using gzip compression and the zlib extension is not enabled.
Example #1 A Phar::compressAllFilesBZIP2() 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->isCompressedBZIP2());
var_dump($file->isCompressedGZ());
}
$p->compressAllFilesBZIP2();
foreach ($p as $file) {
var_dump($file->getFileName());
var_dump($file->isCompressed());
var_dump($file->isCompressedBZIP2());
var_dump($file->isCompressedGZ());
}
?>
上例将输出：
string(10) "myfile.txt" bool(false) bool(false) bool(false) string(11) "myfile2.txt" bool(false) bool(false) bool(false) string(10) "myfile.txt" bool(true) bool(true) bool(false) string(11) "myfile2.txt" bool(true) bool(true) bool(false)
