# PharFileInfo->setUncompressed

(no version information, might be only in CVS)

PharFileInfo->setUncompressed -- Uncompresses the current Phar entry within the phar, if it is compressed

## 说明

bool PharFileInfo->setUncompressed ( void )

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.

## 错误／异常

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

## 范例

例 1. A PharFileInfo->setUncompressed() example

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

上例将输出：

    bool(true)
    bool(false)
