What potential issues, such as popup blockers or disabled JavaScript, can prevent a popup window from opening despite correct PHP coding?

Potential issues such as popup blockers or disabled JavaScript can prevent a popup window from opening despite correct PHP coding. To solve this issue, you can use a JavaScript function to open the popup window instead of relying solely on PHP. 

echo '<script type="text/javascript">
        function openPopup(url) {
            window.open(url, "_blank", "width=600,height=400");
        }
      </script>';
      
echo '<button onclick="openPopup(\'popup.html\')">Open Popup</button>';
