Used to determine whether Phar write operations are being buffered, or are flushing directly to disk
Description
Phar::isBuffering(): 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.
Parameters Parameters
Return Values
Returns true if the write operations are being buffer, false otherwise.
