[SOLVED] error with stylesheet and php in JS

[BoltZ]

<script type="text/javascript">
var browserName=navigator.appName;
if (browserName=="Netscape")//Mozilla Firefox Chrome
{
<? echo '<link rel="stylesheet" type="text/css" href="stylesheet.css" />'; ?>
}
else
{
if (browserName=="Microsoft Internet Explorer")
{
  <? echo '<link rel="stylesheet" type="text/css" href="iestyle.css" />'; ?>
}
else //Opera Safari
  {
    <? echo '<link rel="stylesheet" type="text/css" href="stylesheet.css" />'; ?>
   }
}

</script>

I have this code to find the browser then echo the stylesheet. and this code works fine in the navigator part sense but the error i am sure is that i am not sure if i am allowed to call php in JS. anyone know a way to make it display the stylesheet according to the browser since i cant echo php?

JS is client-side, and PHP is server-side. If you view your source, that's exactly what JS will be running. "echo" is PHP code, and it's gonna echo whether the JS wants it to or not.

But i tried that code in a offline status with an alert instead of that echo stuff and it worked fine. Never mind anymore i decided to simply use get_browser function from php since you cant disable php

Yeah. "alert" is JavaScript, and "echo" is PHP. Therefore, using "alert" in JS would work, and using "echo" would not.

Yea i decided in the end to make it so i use the get_browser functionn in php since people can't disable PHP
