# Phar::uncompressAllFiles

(PECL phar < 2.0.0)

Phar::uncompressAllFiles — Uncompresses all files in the current Phar archive

### Description

public Phar::uncompressAllFiles ( ) : bool

> Note:

> This method has been removed from the phar extension as of version 2.0.0. Alternative implementations are available using Phar::compress(), Phar::decompress(), Phar::compressFiles() and Phar::decompressFiles().

> Note:

> This method requires the php.ini setting `phar.readonly` to be set to `0` in order to work for Phar objects. Otherwise, a PharException will be thrown.

This method decompresses all files in the Phar archive. If any files are already compressed using gzip compression, the zlib extension must be enabled in order to decompress the files, and any files compressed using bzip2 compression require the bzip2 extension to decompress the files. As with all functionality that modifies the contents of a phar, the phar.readonly INI variable must be off in order to succeed.

### Return Values

Returns `TRUE` on success or `FALSE` on failure.

### Errors/Exceptions

Throws BadMethodCallException if the phar.readonly INI variable is on, the bzip2 extension is not enabled and any files are compressed using bzip2 compression, or if any files are compressed using gzip compression and the zlib extension is not enabled.

### Examples

Example #1 A Phar::uncompressAllFiles() example

`<?php
try {
$p = new Phar('/path/to/my.phar', 0, 'my.phar');
$p['myfile.txt'] = 'hi';
$p['myfile2.txt'] = 'hi';
$p->compressAllFilesGZ();
foreach ($p as $file) {
var_dump($file->getFileName());
var_dump($file->isCompressed());
var_dump($file->isCompressedBZIP2());
var_dump($file->isCompressedGZ());
}
$p->uncompressAllFiles();
foreach ($p as $file) {
var_dump($file->getFileName());
var_dump($file->isCompressed());
var_dump($file->isCompressedBZIP2());
var_dump($file->isCompressedGZ());
}
} catch (Exception $e) {
echo 'Write operations failed on my.phar: ', $e;
}
?>`

The above example will output:

    string(10) "myfile.txt"
    bool(true)
    bool(false)
    bool(true)
    string(11) "myfile2.txt"
    bool(true)
    bool(false)
    bool(true)
    string(10) "myfile.txt"
    bool(false)
    bool(false)
    bool(false)
    string(11) "myfile2.txt"
    bool(false)
    bool(false)
    bool(false)
