PHP Repairs and compacts this database

说明

public array MongoDB::repair ([ bool $preserve_cloned_files = FALSE [, bool $backup_original_files = FALSE ]] )

This creates a fresh copy of all database data. It will remove any corrupt data and compact and large stretches of free space it finds. This is a very slow operation on a large database.

This is usually run from the shell or the command line, not the driver.

It is equivalent to the function:


<?php

public function repair() {
    return $this->command(array('repairDatabase' => 1));
}

?>

参数

preserve_cloned_files: If cloned files should be kept if the repair fails.
backup_original_files: If original files should be backed up.

返回值

Returns db response.
