Phar::stopBuffering — Stop buffering write requests to the Phar archive, and save changes to disk
Descrição
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.
Valor Retornado
Não há valor retornado.
Erros
PharException is thrown if any problems are encountered flushing changes to disk.
Exemplos
Exemplo #1 A Phar::stopBuffering() example
<?php
$p = new Phar(dirname(__FILE__) . '/brandnewphar.phar', 0, 'brandnewphar.phar');
$p['file1.txt'] = 'hi';
$p->startBuffering();
var_dump($p->getStub());
$p->setStub("<?php
function __autoload(\$class)
{
include 'phar://brandnewphar.phar/' . str_replace('_', '/', \$class) . '.php';
}
Phar::mapPhar('brandnewphar.phar');
include 'phar://brandnewphar.phar/startup.php';
__HALT_COMPILER();");
$p->stopBuffering();
var_dump($p->getStub());
?>
O exemplo acima irá imprimir:
string(24) "<?php __HALT_COMPILER();"
string(195) "<?php
function __autoload($class)
{
include 'phar://' . str_replace('_', '/', $class);
}
Phar::mapPhar('brandnewphar.phar');
include 'phar://brandnewphar.phar/startup.php';
__HALT_COMPILER();"
