Phar::isCompressed()
(PHP 5 >= 5.3.0, PHP 7, PECL phar >= 2.0.0)
Returns Phar::GZ or PHAR::BZ2 if the entire phar archive is compressed(.tar.gz/tar.bz and so on)
说明
public Phar::isCompressed(void): mixed
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.
参数
No parameters.
返回值
Phar::GZ,Phar::BZ2or FALSE
范例
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)
