(PHP 5 >= 5.3.0, PHP 7, PECL phar >= 1.0.0)
PharFileInfo::isCompressedBZIP2 — Returns whether the entry is compressed using bzip2
说明
public PharFileInfo::isCompressedBZIP2 ( void ) : boolNote:
此方法已经从 phar 扩展 2.0.0以上版本中删除。可使用 PharFileInfo::isCompressed()，PharFileInfo::decompress() 和 PharFileInfo::compress()替代。
This returns whether a file is compressed within a Phar archive with Bzip2 compression.
返回值
TRUE if the file is compressed within the Phar archive using Bzip2, FALSE if not.
范例
Example #1 A PharFileInfo::isCompressedBZIP2() example
<?php
try {
$p = new Phar('/path/to/my.phar', 0, 'my.phar');
$p['myfile.txt'] = 'hi';
$p['myfile2.txt'] = 'hi';
$p['myfile3.txt'] = 'hi';
$p['myfile2.txt']->setCompressedGZ();
$p['myfile3.txt']->setCompressedBZIP2();
$file = $p['myfile.txt'];
$file2 = $p['myfile2.txt'];
$file3 = $p['myfile3.txt'];
var_dump($file->isCompressedBZIP2());
var_dump($file2->isCompressedBZIP2());
var_dump($file3->isCompressedBZIP2());
} catch (Exception $e) {
echo 'Create/modify on phar my.phar failed: ', $e;
}
?>
以上例程会输出：
bool(false) bool(false) bool(true)
