PharFileInfo::isCompressedBZIP2()

(PHP 5 >= 5.3.0, PHP 7, PECL phar >= 1.0.0)

Returns whether the entry is compressed using bzip2

说明

publicPharFileInfo::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)
