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)
Description
public Phar::isCompressed(): int|false
Note:
This method requires the php.ini setting
phar.readonlyto be set to0in 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.
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());
$phar2->compress(Phar::GZ);
var_dump($phar2->isCompressed() == Phar::GZ);
} catch (Exception $e) {
}
?>
The above example will output:
bool(false) bool(false) bool(true)
