# Phar::isCompressed

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

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

### Opis

mixed Phar::isCompressed ( void )

> Informacja: Ta metoda wymaga ustawienia w php.ini wartości phar.readonly na 0 aby działała z obiektami Phar. W przeciwnym przypadku, klasa PharException zwróci wyjątek .

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.

### Parametry

No parameters.

### Zwracane wartości

Phar::GZ, Phar::BZ2 or `FALSE`
