# Phar->isBuffering

(no version information, might be only in CVS)

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

## Description

void 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)
