当我为PHP变量赋值时，是否可以调用JavaScript函数？

Question

As soon as I assign a value to my PHP variable $msg...

$msg = 'Some message'; 

... I want to call a JS function like this :

function showSuccess() { 
    alert('success')
}

Is it possible ?

If I understand you correctly, this will be the answer for your question.

$msg = 'some value your are going to assign';

if($msg) //checking $msg variable has some value or not
{
   print '<script type="text/javascript">showSuccess()</script>'; 

   /* or */

   print '<script type="text/javascript">alert("succeess")</script>'; 
}
