# Phar->stopBuffering

(no version information, might be only in CVS)

Phar->stopBuffering -- Stop buffering write requests to the Phar archive, and save changes to disk

## Descrição

void Phar->stopBuffering ( void )

stopBuffering() is used in conjunction with the startBuffering() method. 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 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.

## Erros/Excessões

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();"
