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

说明

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.

范例

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());
?>

上例将输出:

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