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. </para> <para> 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 <function>startBuffering</function>/<function>stopBuffering</function> pair of methods is provided for this purpose. </para> <para> Phar write buffering is per-archive, buffering active for the <literal>foo.phar</literal> Phar archive does not affect changes to the <literal>bar.phar</literal> Phar archive. </para> </refsect1> <refsect1 role="examples"> &reftitle.examples; <para> <example> <title>A <function>Phar->startBuffering</function> example</title> <para> </para> <programlisting role="php"> <![CDATA[ <?php // make sure it doesn't exist @unlink('brandnewphar.phar'); try { $p = new Phar(dirname(__FILE__) .
