Phar::stopBuffering
(PHP 5 >= 5.3.0, PHP 7, PHP 8, PECL phar >= 1.0.0)
Phar::stopBuffering — Stop buffering write requests to the Phar archive, and save changes to disk
Descrizione
Phar::stopBuffering() is used in conjunction with the Phar::startBuffering() method. Phar::startBuffering() 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 Phar::startBuffering()/Phar::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.
