PHP 8.3.0 RC 6 available for testing

PharFileInfo::decompress

(PHP 5 >= 5.3.0, PHP 7, PHP 8, PECL phar >= 2.0.0)

PharFileInfo::decompressDecompresses the current Phar entry within the phar

说明

public PharFileInfo::decompress(): bool

This method decompresses the file inside the Phar archive. Depending on how the file is compressed, the bzip2 or zlib extensions must be enabled to take advantage of this feature. As with all functionality that modifies the contents of a phar, the phar.readonly INI variable must be off in order to succeed if the file is within a Phar archive. Files within PharData archives do not have this restriction.

参数

此函数没有参数。

返回值

成功时返回 true, 或者在失败时返回 false

错误/异常

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

示例

示例 #1 A PharFileInfo::decompress() example

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

以上示例会输出:

 
int(4096)
bool(false)
