Output the <script> tag like this:

<?php
function run_javascript($script_code){
    print "
    <script language='javascript'>
    <!--
      $script_code
    // -->
    </script>
    ";
}

run_javascript(" alert('I´m javascript here!'); ");
?>

You can't do that, PHP is a server-side language, that means it renders when the page loads and not after that.

The solution can be to call a PHP via AJAX, that PHP can have the case conditions and then it will render what you want.

Example:

The javascript (using jQuery):

$(".yourbutton").click(function(event){
        event.preventDefault();

        $.post("yourPHP.php", {var: somethingdynamicpassedviajavascript},
            function(data){
                //get ther result
                 $("#yourdiv").html(data);
            }, "html");
    });

What this does is place a click event into something with a class named "yourbutton", and when you click that, it will call an external PHP via an AJAX post, sending a var (in this example), you can send something dynamic, change the "somethingdiynamicpassedviajavascript" with some var.

PHP (yourPHP.php):

$myvar = $_REQUEST['var'];

//do your cases here:

switch ($myvar) {
    case "1":
        echo "this is for the case 0";
        break;
    case 1:
        echo "this is for the case 1";
        break;
}

Here you get that var, and depending on the case, send a different output. Notice that this may need to add a test for POST and other anti-vandalism methods...

if you're trying to dynamically create a javascript based on some conditions you're looking for something link this:

<script language="javascript" type="text/javascript">
<?
    if ($something == $somethingelse)
    {
        echo 'var something = 10;';
    }
    else
    {
        echo 'var somethingelse = 25;';
    }
?>
</script>

if you're to execute php-code via javascript ... that can't really be done, at best you can use PHPjs to emulate php-functions.

yes you can do that.. your php scirpt generates/echoe the javascript code in your html page. You just need to play with single and double quotes and escape them properly In large scripts this is quite messy - better to put your js code in a seperate js file
