PharFileInfo->setCompressedBZIP2

(PECL phar:1.0.0-1.2.1)

PharFileInfo->setCompressedBZIP2 — Compresses the current Phar entry within the phar using Bzip2 compression

说明

bool PharFileInfo->setCompressedBZIP2 ( void )

This method compresses the file inside the Phar archive using bzip2 compression. The bzip2 extension must be enabled to take advantage of this feature. In addition, if the file is already compressed using gzip compression, the zlib extension must be enabled in order to decompress the file. As with all functionality that modifies the contents of a phar, the phar.readonly INI variable must be off in order to succeed.

错误／异常

Throws BadMethodCallException if the phar.readonly INI variable is on, or if the bzip2 extension is not available.

范例

Example#1 A PharFileInfo->setCompressedBZIP2() example

<?php
try {
    $p = new Phar('/path/to/my.phar', 0, 'my.phar');
    $p['myfile.txt'] = 'hi';
    $file = $p['myfile.txt'];
    var_dump($file->isCompressedBZIP2());
    $p['myfile.txt']->setCompressedBZIP2();
    var_dump($file->isCompressedBZIP2());
} catch (Exception $e) {
    echo 'Create/modify operations on my.phar failed: ', $e;
}
?>

上例将输出：

bool(false)
bool(true)
