  • Phar::isCompressed()

    (PHP 5 >= 5.3.0, PHP 7, PECL phar >= 2.0.0)

    Returns Phar::GZ or PHAR::BZ2 if the entire phar archive is compressed(.tar.gz/tar.bz and so on)

    说明

    publicPhar::isCompressed(void): mixed
    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.

    Returns Phar::GZ or PHAR::BZ2 if the entire phar archive is compressed(.tar.gz/tar.bz and so on). Zip-based phar archives cannot be compressed as a file, and so this method will always return FALSE if a zip-based phar archive is queried.

    参数

    No parameters.

    返回值

    Phar::GZ,Phar::BZ2or FALSE

    范例

    A Phar::isCompressed() example

    <?php
    try {
        $phar1 = new Phar('myphar.zip.phar');
        var_dump($phar1->isCompressed());
        $phar2 = new Phar('myuncompressed.tar.phar');
        var_dump($phar2->isCompressed());
        $phar2->compress(Phar::GZ);
        var_dump($phar2->isCompressed() == Phar::GZ);
    } catch (Exception $e) {
    }
    ?>
    

    以上例程会输出:

    bool(false)
    bool(false)
    bool(true)
