Natively Connect to Google Analytics Data in PHP

Create PHP applications on Linux/UNIX machines with connectivity to Google Analytics data. Leverage the native support for ODBC in PHP.

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

Using the CData ODBC Drivers on a UNIX/Linux Machine

The CData ODBC Drivers are supported in various Red Hat-based and Debian-based systems, including Ubuntu, Debian, RHEL, CentOS, and Fedora. There are also several libraries and packages that are required, many of which may be installed by default, depending on your system. For more information on the supported versions of Linux operating systems and the required libraries, please refer to the "Getting Started" section in the help documentation (installed and found online).

Installing the Driver Manager

Before installing the driver, check that your system has a driver manager. For this article, you will use unixODBC, a free and open source ODBC Driver manager that is widely supported.

For Debian-based systems like Ubuntu, you can install unixODBC with the APT package manager:


$ sudo apt-get install unixodbc unixodbc-dev

For systems based on Red Hat Linux, you can install unixODBC with yum or dnf:


$ sudo yum install unixODBC unixODBC-devel

The unixODBC driver manager reads information about drivers from an odbcinst.ini file and about data sources from an odbc.ini file. You can determine the location of the configuration files on your system by entering the following command into a terminal:


$ odbcinst -j

The output of the command will display the locations of the configuration files for ODBC data sources and registered ODBC drivers. User data sources can only be accessed by the user account whose home folder the odbc.ini is located in. System data sources can be accessed by all users. Below is an example of the output of this command:


DRIVERS............: /etc/odbcinst.ini
SYSTEM DATA SOURCES: /etc/odbc.ini
FILE DATA SOURCES..: /etc/ODBCDataSources
USER DATA SOURCES..: /home/myuser/.odbc.ini
SQLULEN Size.......: 8
SQLLEN Size........: 8
SQLSETPOSIROW Size.: 8

Installing the Driver

You can download the driver in standard package formats: the Debian .deb package format or the .rpm file format. Once you have downloaded the file, you can install the driver from the terminal.

The driver installer registers the driver with unixODBC and creates a system DSN, which can be used later in any tools or applications that support ODBC connectivity.

For Debian-based systems like Ubuntu, run the following command with sudo or as root: $ dpkg -i /path/to/package.deb

For Red Hat systems or other systems that support .rpms, run the following command with sudo or as root: $ rpm -i /path/to/package.rpm

Once the driver is installed, you can list the registered drivers and defined data sources using the unixODBC driver manager:

List the Registered Driver(s)


$ odbcinst -q -d
CData ODBC Driver for Google Analytics
...

List the Defined Data Source(s)


$ odbcinst -q -s
CData GoogleAnalytics Source
...

To use the CData ODBC Driver for Google Analytics with unixODBC, ensure that the driver is configured to use UTF-16. To do so, edit the INI file for the driver (cdata.odbc.googleanalytics.ini), which can be found in the lib folder in the installation location (typically /opt/cdata/cdata-odbc-driver-for-googleanalytics), as follows:

cdata.odbc.googleanalytics.ini


...

[Driver]
DriverManagerEncoding = UTF-16

Modifying the DSN

The driver installation predefines a system DSN. You can modify the DSN by editing the system data sources file (/etc/odbc.ini) and defining the required connection properties. Additionally, you can create user-specific DSNs that will not require root access to modify in $HOME/.odbc.ini.

Google uses the OAuth authentication standard. To access Google APIs on behalf on individual users, you can use the embedded credentials or you can register your own OAuth app.

OAuth also enables you to use a service account to connect on behalf of users in a Google Apps domain. To authenticate with a service account, you will need to register an application to obtain the OAuth JWT values.

In addition to the OAuth values, set Profile to the profile you want to connect to. This can be set to either the Id or website URL for the Profile. If not specified, the first Profile returned will be used.

/etc/odbc.ini or $HOME/.odbc.ini


[CData GoogleAnalytics Source]
Driver = CData ODBC Driver for Google Analytics
Description = My Description
Profile = MyProfile

For specific information on using these configuration files, please refer to the help documentation (installed and found online).

Establish a Connection

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


$conn = odbc_connect("CData ODBC GoogleAnalytics 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.


$conn = odbc_pconnect("CData ODBC GoogleAnalytics Source","user","password");
...
odbc_close($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 Traffic WHERE Transactions = ?");

Execute Queries

Execute prepared statements with odbc_execute.


$conn = odbc_connect("CData ODBC GoogleAnalytics Source","user","password");
$query = odbc_prepare($conn, "SELECT * FROM Traffic WHERE Transactions = ?");
$success = odbc_execute($query, array('0'));

Execute nonparameterized queries with odbc_exec.


$conn = odbc_connect("CData ODBC GoogleAnalytics Source","user","password");
$query = odbc_exec($conn, "SELECT Browser, Sessions FROM Traffic");

Process Results

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


$conn = odbc_connect("CData ODBC Google Analytics data Source","user","password");
$query = odbc_exec($conn, "SELECT Browser, Sessions FROM Traffic");
while($row = odbc_fetch_array($query)){
 echo $row["Browser"] . "\n";
}

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


$conn = odbc_connect("CData ODBC Google Analytics data Source","user","password");
$query = odbc_prepare($conn, "SELECT * FROM Traffic WHERE Transactions = ?");
$success = odbc_execute($query, array('0'));
if($success)
  odbc_result_all($query);

More Example Queries

You will find complete information on the SQL queries supported by the driver in the help documentation. The code examples above are Google Analytics-specific adaptations of the PHP community documentation for all ODBC functions.
