使用PHP脚本执行JS <script> tag on the homepage only

Question

I am trying to create a statement in PHP that will make a survey monkey popup appear on the homepage of a website and not on the other pages.

I've tried the below code and different variations of it to try and get it to work. I can add the popup to the entire site by just putting the element into the of the website but when I try to get it to appear only on the homepage, nothing shows up at all.

I've tried it using just one 'echo' instead of splitting it into three and also using /index.php instead of /.

<?php
if ($_SERVER["SCRIPT_NAME"] == '/') { 
  echo '<script>';
  echo '(function(t,e,s,o){var n,a,c;t.SMCX=t.SMCX||[],e.getElementById(o)||(n=e.getElementsByTagName(s),a=n[n.length-1],c=e.createElement(s),c.type="text/javascript",c.async=!0,c.id=o,c.src=["https:"===location.protocol?"https://":"http://","widget.surveymonkey.com/collect/website/js/tRaiETqnLgj758hTBazgd_2Fw5nxAtNDAAqLsYqzVv_2FShi5yryjY3psD6EYInvUCYX.js"].join(""),a.parentNode.insertBefore(c,a))})(window,document,"script","smcx-sdk");';
  echo '</script>';
 }

?>

I have found some similar questions on here but none that quite fit my situation, I've also tried out some of their answers recommendation but they don't seem to work.

Any help would be greatly appreciated, I feel like it's something so simple and I'm just complicating matters. Hopefully I've provided enough information for you all!

PHP solution:

$active_location = $_SERVER['HTTP_HOST'].$_SERVER["REQUEST_URI"]; 
$host_name = $_SERVER['HTTP_HOST']; 
if ($active_location == $host_name || $active_location == $host_name.'/'){
//stuff you want to do
}

the $active_location will return the current full url without the ssl sertivication the $host_name wil give the hostname without ssl. if they are the same the code will run.

The OR (||) statemant is because in some cases the homepage will will have an / without you seeing it, if you don't put the statment the code will not run is some cases.
