PharFileInfo::isCompressedBZIP2()
(PHP 5 >= 5.3.0, PHP 7, PECL phar >= 1.0.0)
Returns whether the entry is compressed using bzip2
说明
public PharFileInfo::isCompressedBZIP2(void): bool
Note: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
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)
