BR tag with php variables are not working

This is the problem that i am facing.

$value1=100;
$value2=5;

if i multiply the value like this, with a br tag at the end,

echo $value1*=$value2."</br>";

br tag is not working at all.

Can anyone help?. Thanks in Advance

Answer

You could do :

echo ($value1*=$value2) . "<br/>";
