Phar::isCompressed

(PHP 5 >= 5.3.0, PHP 7, PHP 8, 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)

Descrizione

public Phar::isCompressed(): int|false

Nota:
This method requires the php.ini setting phar.readonly to be set to 0 in order to work for Phar objects. Otherwise, a PharException will be thrown.

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.

Elenco dei parametri

No parameters.

Valori restituiti

Phar::GZ, Phar::BZ2 or false.
