Php Resolution

[xianaier]

Hello, I was just wondering if there is anyway I can get the user resolution using php.

What I am trying to do is have different stylesheets for the same page depending on the user's resolution. All help appreciated.

I tried with javascript but I have to redirect to a different page to do it.

PHP does not provide a function to detect the screen resolution for displaying information about the visitor is not provided natively by the HTTP protocol. by Javascript to detect against the resolution through the width and height attributes of the object screen:

screen.width
screen.height

Thus the following code, when inserted into an HTML document, displays the display resolution of the visitor:

<script language="Javascript">
<! -
document.write ('simply enter your resolution is'. screen.width + 'x' + screen.height)
//-->
</ Script>

Thus, it is possible to pass the parameter to a PHP script via a redirect in Javascript.

<?
if (isset ($ _GET ['r']))
{
echo "<script language=\"JavaScript\">
<! -
document.location = \ "$ PHP_SELF? r = 1 & width = \" + screen.width + \ "& height = \" + screen.height;
//-->
</ Script> ";
}
else {

/ / Code to display upon detection of display resolution
if (isset ($ _GET ['width']) & & isset ($ _GET ['height'])) {
/ / Detected Resolution
}
else {
/ / Resolution not detected
}
}

?>
