Phar::isBuffering — Used to determine whether Phar write operations are being buffered, or are flushing directly to disk
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.
Returns TRUE
if the write operations are being buffer, FALSE
otherwise.
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 ());
?>
以上例程会输出:
bool(false) bool(false) =2= bool(true) bool(false) =3= bool(false) bool(false)
