Natively Connect to Google Search Results in PHP

The CData ODBC driver for Google Search enables you to create PHP applications with connectivity to Google Search results. Leverage the native support for ODBC in PHP.

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

To search with a Google custom search engine, you need to set the CustomSearchId and ApiKey connection properties.

To obtain the CustomSearchId property, sign into Google Custom Search Engine and create a new search engine.

To obtain the ApiKey property, you must enable the Custom Search API in the Google API Console.

Establish a Connection

Open the connection to Google Search by calling the odbc_connect or odbc_pconnect methods. To close connections, use odbc_close or odbc_close_all.

$conn = odbc_connect("CData ODBC GoogleSearch 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.

$conn = odbc_pconnect("CData ODBC GoogleSearch Source","user","password"); ... odbc_close($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 VideoSearch WHERE SearchTerms = ?");

Execute Queries

Execute prepared statements with odbc_execute.

$conn = odbc_connect("CData ODBC GoogleSearch Source","user","password"); $query = odbc_prepare($conn, "SELECT * FROM VideoSearch WHERE SearchTerms = ?"); $success = odbc_execute($query, array('WayneTech'));

Execute nonparameterized queries with odbc_exec.

$conn = odbc_connect("CData ODBC GoogleSearch Source","user","password"); $query = odbc_exec($conn, "SELECT Title, ViewCount FROM VideoSearch WHERE SearchTerms = 'WayneTech'");

Process Results

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

$conn = odbc_connect("CData ODBC Google Search results Source","user","password"); $query = odbc_exec($conn, "SELECT Title, ViewCount FROM VideoSearch WHERE SearchTerms = 'WayneTech'"); while($row = odbc_fetch_array($query)){ echo $row["Title"] . "\n"; }

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

$conn = odbc_connect("CData ODBC Google Search results Source","user","password"); $query = odbc_prepare($conn, "SELECT * FROM VideoSearch WHERE SearchTerms = ?"); $success = odbc_execute($query, array('WayneTech')); 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 Search-specific adaptations of the PHP community documentation for all ODBC functions.
