(PECL mongo >=1.3.0)
MongoClient::listDBs — Lists all of the databases available
This extension that defines this method is deprecated. Instead, the MongoDB extension should be used. There is no equivalent for this method in the new extension, but there is an alternative in the PHP library:
This function has no parameters.
Returns an associative array containing three fields. The first field is
databases, which in turn contains an array. Each element
of the array is an associative array corresponding to a database, giving th
database's name, size, and if it's empty. The other two fields are
totalSize (in bytes) and ok, which is 1
if this method ran successfully.
Example #1 MongoClient::listDBs() example
Example demonstrating how to use listDBs and the returned data structure.
<?php
$mongo = new MongoClient();
$dbs = $mongo->listDBs();
print_r($dbs);
?>
The above example will output something similar to:
Array
(
[databases] => Array
(
[0] => Array
(
[name] => doctrine
[sizeOnDisk] => 218103808
[empty] =>
)
)
[totalSize] => 218103808
[ok] => 1
)
