Screen resolution

Is it possible to take info about user's screen resolution, put it on a variable and do something as

if($screen==800x600){
do something}
else{
do other thing}

?

yes, it is possible, but not with php. U should use client side scripting language- javascript:

Code: Select all

<SCRIPT language="JavaScript">
<!-- this javascript code is right, but i dont say exactly same about syntax. Review it if it will not work

window.location='resolution.php?w='+screen.width+'&h='+screen.height; 

//-->
</SCRIPT>

in page resolution.php u will have global variables $w and $h with screen resulution
Browser Compatibility: NS 4+, IE 5+, Firefox

Not to set screen resulotion, but to know it. I think you understood wrong. php natively can not obtain user's screen's resolution, but using javascript you can pass it to page via $_GET method if you will need. It's sometimes usefull

you really need to know
ex. to make sure the width fits the resolution
otherwise users hate scrolling
so they'll just close your page, and never return again
