The other answers are true, I just forgot to write quotes and javascript did not understand it was a String and gave me an error. The correct code:

   if (document.getElementById("fname").value == "") {
        q = false;
        msg = "<?php echo 'Please fill first name'.$formErrors['fname'].'\n'; ?>";
    }

Why not write it all in php?

<?php
$man = "Jamse";
echo "<script>
function alertMyName() {
    alert('my name is:" . $man . "');
}
</script>";
?>

alert('my name is: <?= $man; ?>');

Since PHP will insert $man on the server side, it's not a separate string that must be combined by JS. All the browser will see is

alert('my name is: Jamse');
