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)

說明

public Phar::isCompressed(): int|false

注意:

此方法需要 將 php.ini 中的 phar.readonly 設(shè)為 0 以適合 Phar 對(duì)象. 否則, 將拋出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.

參數(shù)

No parameters.

返回值

Phar::GZ, Phar::BZ2 or false.

范例

示例 #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) {
}
?>

以上例程會(huì)輸出：

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