Detect the Display Resolution in PHP

There is no native function in PHP that can detect the display resolution. Webmaster insights will help to solve this problem arising in PHP. Java script can be used in this case, which will detect the display resolution. The script will do so, by using the width and height features of the screen. The required code for this has to be inserted into a HTML document. Once it is done, the settings can be switched to the PHP script through proper coding methods.

There is no native function in PHP for detecting a user's display resolution.

You can, however, use Javascript to discover the resolution through the width and height attributes of the screen:

screenidth

screen.height

The following Javascript code will show the display resolution:

It is possible to convert this to PHP code like this:

if(!isset($_GET['r']))

{

echo "

";

}

else {

// Code to be displayed if resolutoin is detected

if(isset($_GET['width']) && isset($_GET['Height'])) {

// Resolution detected

}

else {

// Resolution not detected

}

}

?>
