PHP Manual

Phar::isBuffering

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

Description

public 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.

Return Values

Returns TRUE if the write operations are being buffer, FALSE otherwise.

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)
