Integrate PHP with GA4 using Google Tag Manager (Step by Step)

Follow these steps to integrate PHP with GA4 using Google Tag Manager.

Setup a Google Tag Manager Account and Container

To set up a Google Tag Manager Account and Container, go to the Google Tag Manager.

If you are logged in with your Google ID, it will show you an interface like this.

Google Tag Manager

Now, click the “Create Account” button or “Click here to create an account” button to create a new account.

Set up your account by entering your name and selecting the country where your business is located.

Install the Google Tag Manager Container Code

To install the Google Tag Manager Container Code, go to the Google Tag Manager Container dashboard and navigate to the Admin tab.

GTM Admin

You will see a list of options on the right side. Select the “Install Google Tag Manager” option.

Install Google Tag Manager

You will see two sets of code provided here, one for the <head> section and another for the <body> section.

Installation Instructions

Copy the container code for the <head> section. It should look similar to the following:

<!-- Google Tag Manager -->
(function(w,d,s,l,i){w[l]=w[l]||[];w[l].push({'gtm.start':
new Date().getTime(),event:'gtm.js'});var f=d.getElementsByTagName(s)[0],
j=d.createElement(s),dl=l!='dataLayer'?'&amp;l='+l:'';j.async=true;j.src=
'https://www.googletagmanager.com/gtm.js?id='+i+dl;f.parentNode.insertBefore(j,f);
})(window,document,'script','dataLayer','GTM-MTL5JFC');
<!-- End Google Tag Manager -->

Paste the code into the <head> section of your website’s HTML or PHP template file just before the closing </head> tag.

Add Script

Save the changes to your website’s file and publish your changes in Google Tag Manager to make the container code live on your website.

Once you are done making changes, go to your website and inspect the search to ensure Google Tag Manager is installed successfully.

Verify Google Tag Manager

Once the Google Tag Manager Container code is installed, it will work and provide the foundation for managing and deploying tags, including integrating GA4 and other tracking tools. Remember to test the implementation to ensure the container code functions correctly and captures the desired data.

Go to Google Analytics (analytics.google.com) and sign in with your Google Account.

Once signed in, click on the “Admin” option in the lower-left corner of the screen.

When you are done creating a stream, a new window will pop up where you can see the stream details with Measurement ID.

To get the measurement ID, click on the stream, and you will see stream details there with the measurement ID, as we saw above. Copy that ID, and you can use it anywhere; we will use it further.

I am selecting the “Google Analytics: GA4 Configuration” type here.

Configure the settings of the tag based on your requirements. This includes providing the GA4 Measurement ID, setting up event tracking parameters, enabling enhanced measurement, and more. The specific configuration options will vary depending on the type of tag you selected.

Add the measurement ID of your GA4 property that we created earlier. Also, add the values you want to track or require.
