Question

It’s just an example but can I fix this issue ?

function echoText($text){
    echo $text;
}

$text2 = echoText("Text");
echo "<h1>$text2</h1><br><h2>$text</h2><h3>$text</h3>";

But the result isn’t <h1>, <h2> or <h3>, it’s just simple text.

Answer 1

Your function is not returning the value, but echoing it out.

Try

function echoText($text){
    return $text;
}
