The CData ODBC driver for Google Calendar enables you to create PHP applications with connectivity to Google Calendar data. Leverage the native support for ODBC in PHP.
Drop the CData ODBC Driver for Google Calendar into your LAMP or WAMP stack to build Google Calendar-connected Web applications. This article shows how to use PHP's ODBC built-in functions to connect to Google Calendar 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.
You can connect to Google APIs on behalf of individual users or on behalf of a domain. Google uses the OAuth authentication standard. See the "Getting Started" section of the help documentation for a guide.
Establish a Connection
Open the connection to Google Calendar by calling the odbc_connect or odbc_pconnect methods. To close connections, use odbc_close or odbc_close_all.
$conn = odbc_connect("CData ODBC GoogleCalendar Source","user","password");
Connections opened with odbc_connect are closed when the script ends. Connections opened with the odbc_pconnect 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.
$conn = odbc_pconnect("CData ODBC GoogleCalendar Source","user","password");
...
odbc_close($conn); //persistent connection must be closed explicitly
Create Prepared Statements
Create prepared statements and parameterized queries with the odbc_prepare function.
$query = odbc_prepare($conn, "SELECT * FROM VacationCalendar WHERE SearchTerms = ?");
Execute Queries
Execute prepared statements with odbc_execute.
$conn = odbc_connect("CData ODBC GoogleCalendar Source","user","password");
$query = odbc_prepare($conn, "SELECT * FROM VacationCalendar WHERE SearchTerms = ?");
$success = odbc_execute($query, array('beach trip'));
Execute nonparameterized queries with odbc_exec.
$conn = odbc_connect("CData ODBC GoogleCalendar Source","user","password");
$query = odbc_exec($conn, "SELECT Summary, StartDateTime FROM VacationCalendar");
Process Results
Access a row in the result set as an array with the odbc_fetch_array function.
$conn = odbc_connect("CData ODBC Google Calendar data Source","user","password");
$query = odbc_exec($conn, "SELECT Summary, StartDateTime FROM VacationCalendar");
while($row = odbc_fetch_array($query)){
echo $row["Summary"] . "\n";
}
Display the result set in an HTML table with the odbc_result_all function.
$conn = odbc_connect("CData ODBC Google Calendar data Source","user","password");
$query = odbc_prepare($conn, "SELECT * FROM VacationCalendar WHERE SearchTerms = ?");
$success = odbc_execute($query, array('beach trip'));
if($success)
odbc_result_all($query);
More Example Queries
You will find complete information on the driver's supported SQL in the help documentation. The code examples above are Google Calendar-specific adaptations of the PHP community documentation for all ODBC functions.
