How to split code in two line instead of one

Ok this is this code below, I want to split it into two sections.

look at this code right here

=AMZN

I want to make AMZN separate.

like may be

 $stockId = AMZN;

THIS IS CURRENT CODE ONE LINE

$ret = scraping_IMDB('http://www.nasdaq.com/aspx/nasdaqlastsale.aspx?symbol=AMZN&selected=AMZN');

Please Help Me Split it so instead of changing stock code in whole url I can just change in like stockId...
Hope you can help me
Thank you

$stockId = 'AMZN'; 
$ret = scraping_IMDB('http://www.nasdaq.com/aspx/nasdaqlastsale.aspx?symbol='.$stockId.'&selected='.$stockId);

depending what your scraping there's possibly an api, and just because its on a web site doesn't mean you can use that data anyway you like.

hey dude thanx man that worked.
I was wondering if I can use this instead of AMZN

<script language="JavaScript" type="text/javascript">{ var name = prompt ('Stock Symbol',''); document.write(""+name+"") } </script>

nope because js is server-side and php client side, the php has finished before the js would be called. you pass it to a new page however

Please could you give me more hint what to do
Thank you.
