# PharFileInfo::setCompressedGZ

Compresses the current Phar entry within the phar using gz compression

### Description

public bool PharFileInfo::setCompressedGZ ( void )

> Note:

> This method has been removed from the phar extension as of version 2.0.0. Alternative implementations are available using PharFileInfo::isCompressed, PharFileInfo::decompress, and PharFileInfo::compress.

This method compresses the file inside the Phar archive using gzip compression. The zlib extension must be enabled to take advantage of this feature. In addition, if the file is already compressed using bzip2 compression, the bzip2 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.

### Return Values

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

### Errors/Exceptions

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

### Examples

Example #1 A PharFileInfo::setCompressedGZ example

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

The above example will output:

    bool(false)
    bool(true)
