Phar::compressAllFilesBZIP2 — Compresses all files in the current Phar archive using Bzip2 compression
Note:
此方法已经从 phar 扩展 2.0.0以上版本中删除。可使用 Phar::compress()，Phar::decompress()，Phar::compressFiles() 和 Phar::decompressFiles()替代。
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.
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.
成功时返回 TRUE， 或者在失败时返回 FALSE。
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());
}
?>
以上例程会输出：
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)
