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
Extensia care definește această metodă este învechită. În loc, trtebuie utilizată extensia MongoDB. Nu există un echivalent al acestei metode în noua extensie, însă există o alternativă în biblioteca PHP:
Descrierea
public MongoClient::listDBs
(
) : array
Parametri
Această funcție nu are parametri.
Valorile întoarse
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.
Exemple
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);
?>
Exemplul de mai sus va afișa ceva similar cu:
Array
(
[databases] => Array
(
[0] => Array
(
[name] => doctrine
[sizeOnDisk] => 218103808
[empty] =>
)
)
[totalSize] => 218103808
[ok] => 1
)
