Error in PHP code unexpected "$agent"

Question

I am getting the following error

Parse error: syntax error, unexpected '$agent' (T_VARIABLE) in C:\xampp\htdocs\webconcept2.php on line 3

and the code is given below. I have checked all possible errors of semicolons etc but does not find the error

<?php

 $agent = $_SERVER['HTTP_USER_AGENT'];

if(preg_match('/Linux/i',$agent)) $os = 'Linux';
  elseif(preg_match('/Mac/i',$agent)) $os = '/Mac';
  elseif(preg_match('/iPhone/i',$agent)) $os = 'iPhone';
  elseif(preg_match('/iPad/i',$agent)) $os = 'iPad';
  elseif(preg_match('/Droid/i',$agent)) $os = 'Droid';
  elseif(preg_match('/Unix/i',$agent)) $os = 'Unix';
  elseif(preg_match('/Windows/i',$agent)) $os = 'Windows';
  elseif $os = 'Unknown';
     // Browser Detection
if(preg_match('/Firefox/i',$agent)) $br = 'Firefox';
    elseif(preg_match('Mac/i',$agent)) $br = 'Mac';
    elseif(preg_match('Chrome/i',$agent)) $br = 'Chrome';
    elseif(preg_match('Opera/i',$agent)) $br = 'opera';
    elseif(preg_match('MSIE/i',$agent)) $br = 'IE';
    else $bs = 'Unknown';

?>

first error is elseif $os = 'Unknown';, it is not elseif, it's a else statement — Bhumi Shah, Jun 16 '18 at 07:12
Is `$agent = $_SERVER['HTTP_USER_AGENT'];` the line with the error? If so - it's most likely the code above it. If not then try and indicate in the code which line the error is on. — Nigel Ren, Jun 16 '18 at 07:22
@NigelRen error is possibly in this line but also it is the first line of the code — Sukhi, Jun 16 '18 at 07:41
But it says line 9, which leads me to think there is something above it. — Nigel Ren, Jun 16 '18 at 07:42
@NigelRen above it there is only and which i have delete now — Sukhi, Jun 16 '18 at 07:49

In your last elseif statement in your checks for os detection, you are missing a condition elseif (condition).

What you meant to do is

else $os = 'Unknown';

Also, in your checks for browser detection, your regular expressions are not correct. elseif(preg_match('Mac/i',$agent)). It should be '/Mac/i'
