Phar::isCompressed

(PHP >= 5.3.0, 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)

说明

public mixed Phar::isCompressed ( void )

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::BZ2 or FALSE

范例

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) {
}
?>
