$startTime = str_replace(":", "", 11:30);
$endTime = str_replace(":", "", 16:00);
$currentTime = str_replace(":", "", date('H:i'));

if ($currentTime >= $startTime) 
{
    $buttons = '<a href="javascript:void(0)" class="btn btn-success btn-sm">Start Exam</a>';
}
else if($currentTime < $startTime)
{
    $buttons = '<a href="javascript:void(0)" class="btn btn-info btn-sm">Please wait till start time..</a>';
}
else if($currentTime <= $endTime)
{
    $buttons = '<a href="javascript:void(0)" class="btn btn-danger btn-sm">Exam Over</a>';
}

If you are used to in Carbon package then you can easily do it using below code

for installation of Carbon package use

composer require nesbot/carbon

Add autoload file at the top.

require 'vendor/autoload.php';

use Carbon\Carbon;

Run below code to find time difference.

$start  = new Carbon('2018-10-04 15:00:03');
$end    = new Carbon(date('Y-m-d H:i:s'));
You may use

$start->diff($end)->format('%H:%I:%S');

Hope that, this will solve your problem as well.

See this code that I modified for you.

$startTime = str_replace(":", ":", '11:30');
$endTime = str_replace(":", ":", '16:00');
$currentTime = str_replace(":", "", date('H:i'));


if ($currentTime >= $startTime) {
    $buttons = '<a href="javascript:void(0)" class="btn btn-success btn-sm">Start Exam</a>';
} else if ($currentTime < $startTime) {
    $buttons = '<a href="javascript:void(0)" class="btn btn-info btn-sm">Please wait till start time..</a>';
} else if ($currentTime <= $endTime) {
    $buttons = '<a href="javascript:void(0)" class="btn btn-danger btn-sm">Exam Over</a>';
}

echo $buttons;

I think you should convert the dates into timestamps and then compare the dates.

$startTime = strtotime("11:30");
$endTime = strtotime("16:00");
$currentTime = strtotime(date('H:i'));

You need to initialize dates variables as DateTime and set the time. For example this

$startTime = (new DateTime())->setTime(11, 30,0);
$endTime = (new DateTime())->setTime(16, 0, 0);
$currentTime = new DateTime();
if($currentTime >= $endTime )
{
    $buttons = '<a href="javascript:void(0)" class="btn btn-danger btn-sm">Exam Over</a>';
}
else if ($currentTime >= $startTime) 
{
    $buttons = '<a href="javascript:void(0)" class="btn btn-success btn-sm">Start Exam</a>';
}
else if($currentTime < $startTime)
{
    $buttons = '<a href="javascript:void(0)" class="btn btn-info btn-sm">Please wait till start time..</a>';
}
