the `font` HTML Tag has been deprecated for ages, please use `style` for inline css or proper css — RiggsFolly, Mar 25 '20 at 21:42
Is that pseudo code? If it isn't, it's failing because of parse errors. — Funk Forty Niner, Mar 25 '20 at 23:45

You need to use echo to display HTML inside PHP tags.

The font tag is not supported in HTML5. You're better off using p and changing its colour using CSS.

From your question, it seems like you're trying to loop through an array. It can be done like this:

<?php
foreach($arrayValues as $arrayValue) {
   $Danger = $arrayValue[2];
   if($Danger == "High") {
      echo'<p style="color: red;">'.$Danger.'</p>';
   }else if($Danger == "Medium") {
      echo'<p style="color: green;">'.$Danger.'</p>';
   }
}
?>

You can use ternary operator like:

// this equal to: if () { true } else { if () { true } else { false } }
//                         ^                     ^              ^
//                        red                   green         black (default color) 

$color = $Danger == "High" ? 'red' : ($Danger == "Medium" ? 'green' : 'black');

echo "<font color='$color'>$Danger</font>";

You have to output html as a string using echo command like as:

<?php
if($Danger == "High")
{
echo "<font style=\"color:red\">" +  $Danger + "</font>";
}

... ?>
