simple code, but something is missing

[YigalB]

While trying to run very simple code of javascript from within PHP, it runs when the code is:

<h2>My header</h2>
<script language = 'javascript'>;
alert('here I am');
</script>

<?php
echo "starting Now <BR>";

 

But when the code is:

 

<h2>My header</h2>
<script language = 'javascript'>;
document.write(“xxxx”);
alert('here I am');
</script>

<?php
echo "starting Now <BR>";

 

It fails to run the js code, and also the alert is not executed.

The only thing I added was

document.write(“xxxx”);

What did I miss?

Wrong quotation marks were used.
