# PharFileInfo::decompress

(PHP >= 5.3.0, PECL phar >= 2.0.0)

PharFileInfo::decompress — Decompresses the current Phar entry within the phar

### Descripción

bool PharFileInfo::decompress ( 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 if the file is within a Phar archive. Files within PharData archives do not have this restriction.

### Valores retornados

Devuelve `TRUE` si todo se llevó a cabo correctamente, `FALSE` en caso de fallo.

### Errors/Exceptions

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

### Ejemplos

Example #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;
}
?>`

El resultado del ejemplo seria:

    int(4096)
    bool(false)
