Phar::isBuffering
(PHP 5 >= 5.3.0, PHP 7, PHP 8, PECL phar >= 1.0.0)
Phar::isBuffering — Used to determine whether Phar write operations are being buffered, or are flushing directly to disk
Description
public Phar::isBuffering(): bool
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.
Parameters
This function has no parameters.
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)
