Phar::isBuffering
(PHP >= 5.3.0, PECL phar >= 1.0.0)
Phar::isBuffering — Used to determine whether Phar write operations are being buffered, or are flushing directly to disk
Beschreibung
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.
Rückgabewerte
Returns TRUE if the write operations are being buffer, FALSE otherwise.
Beispiele
Beispiel #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());
?>Das oben gezeigte Beispiel erzeugt folgendeAusgabe:
bool(false)bool(false)=2=bool(true)bool(false)=3=bool(false)bool(false)
