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

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

返回值

Phar::GZ,Phar::BZ2or FALSE
