Contents

(PHP 5 >= 5.3.0, PHP 7, 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 ( void ) : 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.
