Natively Connect to Google Directory Data in PHP

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

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.

Google uses the OAuth authentication standard. You can authorize the data provider to access Google Spreadsheets as an individual user or with a Google Apps Domain service account. See the Getting Started section of the data provider help documentation for an authentication guide.

Establish a Connection

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

$conn = odbc_connect("CData ODBC GoogleDirectory 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.

$conn = odbc_pconnect("CData ODBC GoogleDirectory Source","user","password");
...
odbc_close($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 MyTable WHERE Status = ?");

Execute Queries

Execute prepared statements with .

$conn = odbc_connect("CData ODBC GoogleDirectory Source","user","password");
$query = odbc_prepare($conn, "SELECT * FROM MyTable WHERE Status = ?");
$success = odbc_execute($query, array('confirmed'));
 

Execute nonparameterized queries with .

$conn = odbc_connect("CData ODBC GoogleDirectory Source","user","password");
$query = odbc_exec($conn, "SELECT Id, Description FROM MyTable");
 

Process Results

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

$conn = odbc_connect("CData ODBC Google Directory data Source","user","password");
$query = odbc_exec($conn, "SELECT Id, Description FROM MyTable");
while($row = odbc_fetch_array($query)){
 echo $row["Id"] . "\n";
}

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

$conn = odbc_connect("CData ODBC Google Directory data Source","user","password");
$query = odbc_prepare($conn, "SELECT * FROM MyTable WHERE Status = ?");
$success = odbc_execute($query, array('confirmed'));
if($success)
 odbc_result_all($query);
