Hi.
I'm getting data from a database using php. I need to use the data I got from the DB in javascript function
that is stored in another js file. (I'm generating a bar char using java script functions there)

how can I pass variable from php file to a js file and set a global variable in the js file with the variable the was received from the php file?

or , how can I call js function from the php file ?

Because PHP is running on the server and Javascript runs on the client once PHP has run and the page has been prepared on the server, it should be relatively easy to pass the value of a PHP variable to Javascript.

I've included a prototype code snippet below that I think does what you describe...

If you are creating BarCharts in using Javascript, I can highly recommend the Google gadgets and visualization API.
<?php 
// The PHP code 
  $phpdb_title = DBquery1();
  $phpdb_value = DBquery2();
//etc..
?>
 
<script type="text/javascript">
// The Javascript code 
function drawChart() {  
  var data = new google.visualization.DataTable();
  data.addColumn('string', 'Label');
  data.addColumn('number', 'Value');
  data.addRows(1);
  data.setValue(0, 0, <?=$phpdb_title?>);
  data.setValue(0, 1, <?=$phpdb_value?>);	
}
   
</script>

"I need to use the data I got from the DB in javascript function that is stored in another js file."

You need to clarify WHAT other JS file -- where is it at, and what relation to the form passing data to the PHP file?
