A "no frills" listing of all the databases present can be obtained by means of the simple following steps:
<?php
$conn = new MongoClient("mongodb://localhost");
$dbases = $conn->listDBs();
$num = 0;
foreach ($dbases['databases'] as $dbs) {
$num++;
$dbname = $dbs['name'];
echo "<br> $num. $dbname";
}
?>
On the assumption that you have three databases present, the foregoing will produce an output that will look similar to this:
1. local
2. members
3. test
MongoClient::listDBs
(PECL mongo >=1.3.0)
MongoClient::listDBs — Lists all of the databases available
A extensão que define esse método está obsoleta. Alternativamente, a extensão MongoDB deve ser utilizada. Não há um equivalente deste método na nova extensão, mas exite uma alternativa nas bibliotecas PHP:
Descrição
public MongoClient::listDBs
( void
) : array
Parâmetros
Esta função não possui parâmetros.
Valor Retornado
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.
Exemplos
Exemplo #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);
?>
O exemplo acima irá imprimir algo similar à:
Array
(
[databases] => Array
(
[0] => Array
(
[name] => doctrine
[sizeOnDisk] => 218103808
[empty] =>
)
)
[totalSize] => 218103808
[ok] => 1
)
