This tutorial will help you start sending data from your website to Segment and any of our destinations, using our PHP library. As soon as you’re set up you’ll be able to turn on any new destinations with the flip of a switch!
If you want to dive deeper at any point, check out the PHP reference.
Step 1: Download the library
All set? When you’re ready to install the library, clone the repository from github into your desired application directory. (psst, composer users: we’ve got you covered too!)
git clone https://github.com/segmentio/analytics-php /my/app/folders/
Then, add the following to your PHP script to actually load the Segment analytics library in your code:
Now, you’re ready to actually initialize the module. In our examples, we first rename this module to be
Analytics for convenience. In your initialization script, go ahead and make the following call:
# Setup our Segment tracking and # alias to Analytics for convenience class_alias('Segment', 'Analytics'); Segment::init("YOUR_WRITE_KEY");
You only need to call
init once when your php file is requested. All of your files will then have access to the same
Of course, you’ll want to replace
YOUR_WRITE_KEY with your actual Write Key which you can find in Segment under your project settings. Otherwise all that useful data will be sent straight to
The default PHP consumer is the libcurl consumer. If this is not working well for you, or if you have a high-volume project, you may want to try one of our other consumers like the fork-curl consumer.
All set? Nice, the library’s fully installed! We’re now primed and ready to start recording our first analytics calls about our users.
Step 2: Identify Users
identify method is how you tell Segment who the current user is. It includes a unique User ID and any optional traits that you might know about them.
Here’s what a basic call to
identify might look like:
Segment::identify(array( "userId" => "f4ca124298", "traits" => array( "name" => "Michael Bolton", "email" => "email@example.com" ) ));
That’s identifying Michael by his unique User ID (the one you know him by in your database) and labeling him with
Hold up though! When you actually put that code on your site, you’ll need to replace all those hard-coded strings with details about the currently logged-in user. The easiest way is by keeping a
$user variable around in memory.
Segment::identify(array( "userId" => $user->id, "traits" => array( "name" => $user->fullname, "email" => $user->email ) ));
With that call on your page, you’re now successfully identifying every user that visits your site.
If you only need to use a basic CRM setup, you can call it a day right now. Just switch on Salesforce, Intercom, or any other CRM you’d like to use from our interface and we’ll starting send all of your user data to it!
Of course, lots of analytics tools record more than just identities… they record the actions each user performs too! If you’re looking for a complete event tracking analytics setup, keep reading…
Step 3: Track Actions
track method is how you tell Segment about which actions your users are performing on your site. Every action triggers what we call an “event”, which can also have associated “properties”.
Here’s what a call to
track might look like when a user signs up:
Segment::track(array( "userId" => "f4ca124298", "event" => "Signed Up", "properties" => array( "plan" => "Enterprise" ) ));
That’s just telling us that your user just triggered the Signed Up event and chose your hypothetical Enterprise plan. Properties can be anything you want to record, for example:
Segment::track(array( "userId" => "f4ca124298", "event" => "Article Bookmarked", "properties" => array( "title" => "Snow Fall", "subtitle" => "The Avalanche at Tunnel Creek", "author" => "John Branch" ) ));
You’ll want to track events that are indicators of success for your site, like Signed Up, Item Purchased or Article Bookmarked.
To get started, we recommend tracking just a few important events. You can always add more later!
Once you’ve added a few
track calls, you’re almost done.
Step 4: Flush the data
Finally, you’ll want to call our
flush() method to ensure that all data is sent to our servers. This is normally done automatically by the runtime, but some PHP installations won’t take care of it for you, so it’s worth calling at the end of your script, just to be safe.
And presto, you’re done! You successfully installed PHP tracking. Now you’re ready to turn on any destination you fancy from our interface, margarita in hand.
We just walked through the quickest way to get started with Segment using PHP. You might also want to check out our full PHP reference to see what else is possible, or read about the Tracking API methods to get a sense for the bigger picture.
