Phar::stopBuffering — Stop buffering write requests to the Phar archive, and save changes to disk

Опис

public Phar::stopBuffering(): void

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.

Приклад #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());
?>

Поданий вище приклад виведе:

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();"
