# Phar::isBuffering

(PECL phar:1.0.0-1.2.1)

Phar::isBuffering — Used to determine whether Phar write operations are being buffered, or are flushing directly to disk

### Description

bool Phar::isBuffering ( void )

This method can be used to determine whether a Phar will save changes to disk immediately, or whether a call to Phar->stopBuffering() is needed to enable saving changes.

Phar write buffering is per-archive, buffering active for the foo.phar Phar archive does not affect changes to the bar.phar Phar archive.

### Examples

Example #1 A Phar::isBuffering() example

`<?php
$p = new Phar(dirname(__FILE__) . '/brandnewphar.phar', 0, 'brandnewphar.phar');
$p2 = new Phar('existingphar.phar');
$p['file1.txt'] = 'hi';
var_dump($p->isBuffering());
var_dump($p2->isBuffering());
?>
=2=
<?php
$p->startBuffering();
var_dump($p->isBuffering());
var_dump($p2->isBuffering());
$p->stopBuffering();
?>
=3=
<?php
var_dump($p->isBuffering());
var_dump($p2->isBuffering());
?>`

The above example will output:

    bool(false)
    bool(false)
    =2=
    bool(true)
    bool(false)
    =3=
    bool(false)
    bool(false)
