(no version information, might be only in CVS)Phar->startBuffering -- Start buffering Phar write operations, do not modify the Phar object on disk
Although technically unnecessary, the startBuffering() method can provide a significant performance boost when creating or modifying a Phar archive with a large number of files. Ordinarily, every time a file within a Phar archive is created or modified in any way, the entire Phar archive will be recreated with the changes. In this way, the archive will be up-to-date with the activity performed on it.
However, this can be unnecessary when simply creating a new Phar archive, when it would make more sense to write the entire archive out at once. Similarly, it is often necessary to make a series of changes and to ensure that they all are possible before making any changes on disk, similar to the relational database concept of transactions. the startBuffering()/stopBuffering() pair of methods is provided for this purpose.
Phar write buffering is per-archive, buffering active for the foo.phar Phar archive does not affect changes to the bar.phar Phar archive.
