# Phar::isCompressed

(No version information available, might be only in CVS)

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

### Description

bool|int Phar::isCompressed ( void )

> Note: 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 archive is queried.

### Parameters

No parameters.

### Return Values

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

### Examples

Example#1 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());
$phar2->compressAllFilesGZ();
var_dump($phar2->isCompressed() == Phar::GZ);
} catch (Exception $e) {
}
?>`

The above example will output:

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