can javascript merge with php?...if so,how can we implement it...
i had a hard time searching on that problem....
i made experiments but it doesn't work...hehe;)

You can use PHP to generate JavaScript in a client side script, but if you are talking about getting PHP (a server side language) to talk to JavaScript as a client-side language, you cannot do it.

PHP is executed on the server. JavaScript in a Web page is executed in the user's browser.

Actually, you can code functions in javascript that talk to php. You send data and get a response. AJAX.

This whole forum uses that ability. But, as pointed out, the javascript runs on your browser, and the php on the webserver. But the two talk.

I sometimes find that I need to use PHP to generate a JavaScript array that is used by an application. In this situation, I am probably using data in a MySQL database to generate the array. This is no different than when you generate any other client-side code.

For example, if you had a MySQL table loaded with names of books that you want to use to generate a JavaScript array, you would do something like this:

<?php
  echo "var bNames = new Array(";

  $sql = "SELECT book_name FROM books ORDER by book_name";

  $rs = mysql_query($sql);

  while($row = mysql_fetch_array($rs))
  { 
    echo "\"".$row['book_name']."\",";
  }
  echo "\"\"";
  echo ");\n";
  ?>

This generates the following client-side JavaScript array:

var bNames = new Array("book name 1","book name 2","book name 3","");

Before you jump into using JavaScript heavily for Web applications, keep in mind that JavaScript should never be used for a critical function. According to the W3Schools surveys, up to 10% of users have JavaScript disabled in their browsers. I think this is mostly due to people who set the security level to high in Internet Explorer, which disables all active scripting, including JavaScript.

You echo out the javascript like any html. The example above while not complete, explains echo.
