Natively Connect to LinkedIn Ads Data in PHP

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

LinkedIn Ads uses the OAuth authentication standard. OAuth requires the authenticating user to interact with LinkedIn using the browser. See the OAuth section in the Help documentation for a guide.

Establish a Connection

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

$conn = odbc_connect("CData ODBC LinkedInAds 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.

$conn = odbc_pconnect("CData ODBC LinkedInAds Source","user","password");
...
odbc_close($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 Analytics WHERE EntityId = ?");

Execute Queries

Execute prepared statements with .

$conn = odbc_connect("CData ODBC LinkedInAds Source","user","password");
$query = odbc_prepare($conn, "SELECT * FROM Analytics WHERE EntityId = ?");
$success = odbc_execute($query, array('238'));
 

Execute nonparameterized queries with .

$conn = odbc_connect("CData ODBC LinkedInAds Source","user","password");
$query = odbc_exec($conn, "SELECT VisibilityCode, Comment FROM Analytics WHERE EntityId = '238'");
 

Process Results

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

$conn = odbc_connect("CData ODBC LinkedIn Ads data Source","user","password");
$query = odbc_exec($conn, "SELECT VisibilityCode, Comment FROM Analytics WHERE EntityId = '238'");
while($row = odbc_fetch_array($query)){
 echo $row["VisibilityCode"] . "\n";
}

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

$conn = odbc_connect("CData ODBC LinkedIn Ads data Source","user","password");
$query = odbc_prepare($conn, "SELECT * FROM Analytics WHERE EntityId = ?");
$success = odbc_execute($query, array('238'));
if($success)
 odbc_result_all($query);
