(PHP 5 >= 5.3.0, PHP 7, 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)
Note:
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.
No parameters.
Phar::GZ, Phar::BZ2 or FALSE
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) {
}
?>
以上例程会输出：
bool(false) bool(false) bool(true)
