Natively Connect to MongoDB Data in PHP

Drop the CData ODBC Driver for MongoDB into your LAMP or WAMP stack to build MongoDB-connected Web applications. This article shows how to use PHP's ODBC built-in functions to connect to MongoDB data, execute queries, and output the results.

Getting Started

---

Configure a DSN

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

Set the Server, Database, User, and Password connection properties to connect to MongoDB. To access MongoDB collections as tables you can use automatic schema discovery or write your own schema definitions. Schemas are defined in .rsd files, which have a simple format. You can also execute free-form queries that are not tied to the schema.

Establish a Connection

Open the connection to MongoDB by calling the or methods. To close connections, use or .

$conn = odbc_connect("CData ODBC MongoDB Source","user","password");

Connections opened with are closed when the script ends. Connections opened with the method are still open after the script ends. This enables other scripts to share that connection when they connect with the same credentials. By sharing connections among your scripts, you can save system resources, and queries execute faster.

$conn = odbc_pconnect("CData ODBC MongoDB Source","user","password");
...
odbc_close($conn); //persistent connection must be closed explicitly

Create Prepared Statements

Create prepared statements and parameterized queries with the function.

$query = odbc_prepare($conn, "SELECT * FROM restaurants WHERE Name = ?");

Execute Queries

Execute prepared statements with .

$conn = odbc_connect("CData ODBC MongoDB Source","user","password");
$query = odbc_prepare($conn, "SELECT * FROM restaurants WHERE Name = ?");
$success = odbc_execute($query, array('Morris Park Bake Shop'));
 

Execute nonparameterized queries with .

$conn = odbc_connect("CData ODBC MongoDB Source","user","password");
$query = odbc_exec($conn, "SELECT borough, cuisine FROM restaurants");
 

Process Results

Access a row in the result set as an array with the function.

$conn = odbc_connect("CData ODBC MongoDB data Source","user","password");
$query = odbc_exec($conn, "SELECT borough, cuisine FROM restaurants");
while($row = odbc_fetch_array($query)){
 echo $row["borough"] . "\n";
}

Display the result set in an HTML table with the function.

$conn = odbc_connect("CData ODBC MongoDB data Source","user","password");
$query = odbc_prepare($conn, "SELECT * FROM restaurants WHERE Name = ?");
$success = odbc_execute($query, array('Morris Park Bake Shop'));
if($success)
 odbc_result_all($query);
