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
Опис
public 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.
Значення, що повертаються
Returns TRUE if the write operations are being buffer, FALSE otherwise.
