Answer 1

Try this

$this->load->library('user_agent');
if ($this->agent->browser() != 'Internet Explorer'){
   echo "browser not supported";
}

Answer 2

if you wan to do this by JS than try this..

if((navigator.userAgent.indexOf("MSIE") != -1 ) || (!!document.documentMode == true )) //IF IE > 10
    {
        alert('EI');
    }else{
        alert('noooooo');
    }

Answer 3

here is a js code where you can identify any browser and based on that you can display your page

// Opera 8.0+
var isOpera = (!!window.opr && !!opr.addons) || !!window.opera || navigator.userAgent.indexOf(' OPR/') >= 0;

// Firefox 1.0+
var isFirefox = typeof InstallTrigger !== 'undefined';

// Safari 3.0+ "[object HTMLElementConstructor]" 
var isSafari = /constructor/i.test(window.HTMLElement) || (function (p) { return p.toString() === "[object SafariRemoteNotification]"; })(!window['safari'] || (typeof safari !== 'undefined' && safari.pushNotification));



// Chrome 1 - 71
var isChrome = !!window.chrome && (!!window.chrome.webstore || !!window.chrome.runtime);

// Blink engine detection
var isBlink = (isChrome || isOpera) && !!window.CSS;

-------------------------
// Internet Explorer 6-11
var isIE = /*@cc_on!@*/false || !!document.documentMode;

// Edge 20+
var isEdge = !isIE && !!window.StyleMedia;

if(isIE){
    //show body
}else{
    //show message
}
