Code in functions.php ?

Hello, just asking to be sure:

Can I include both Google Analytics code and PiwikPro code in my functions.php like this:

function piwik_analytics_header(){
?>
<script type=”text/javascript”>
var _paq = _paq || [];
_paq.push([“setTimingDataSamplingOnPageLoad”, 100]);
_paq.push([“trackPageView”]);
_paq.push([“enableLinkTracking”]);
(function() {
var u = “https://xxxxxxxxxxx.piwik.pro/&#8221;;
_paq.push([“setTrackerUrl”, u + “ppms.php”]);
_paq.push([“setSiteId”, “xxxxxxxxxxxxxxxxxxxx”]);
var d = document,
g = d.createElement(“script”),
s = d.getElementsByTagName(“script”)[0];
g.type = “text/javascript”;
g.async = true;
g.defer = true;
g.src = u + “ppms.js”;
s.parentNode.insertBefore(g, s);
})();
</script>
<?php
}
add_action(‘wp_head’, ‘piwik_analytics_header’);

function google_analytics_header(){
?>
<!– Google tag (gtag.js) –>
<script async src=”https://www.googletagmanager.com/gtag/js?id=G-xxxxxxxxxxxxxxxx”></script&gt;
<script>
window.dataLayer = window.dataLayer || [];
function gtag(){dataLayer.push(arguments);}
gtag(‘js’, new Date());

gtag(‘config’, ‘G-xxxxxxxxxxxxxxx’);
</script>
<?php
}
add_action(‘wp_head’, ‘google_analytics_header’);`
`

Two analytics services in my functions.php like this aren’t going to conflict with each other?
Seems to me it’s working fine, but like to be sure.
