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 -> 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)
