How to Compare Times in PHP and Fix a Common Error?

Comparing Times in PHP

In PHP, comparing times can be achieved using different approaches. Let's explore them and resolve a specific issue in comparing times.

Problem:
The given code fails to compare time correctly and output "ok" as expected:

$ThatTime ="14:08:10";
$todaydate = date('Y-m-d');
$time_now=mktime(date('G'),date('i'),date('s'));
$NowisTime=date('G:i:s',$time_now);
if($NowisTime >= $ThatTime) {
    echo "ok";
}

Solution 1:
Use the strtotime() function to convert the time string to a timestamp:

$ThatTime ="14:08:10";
if (time() >= strtotime($ThatTime)) {
  echo "ok";
}

Solution 2:
Utilize the DateTime class, which also considers time zones:

$dateTime = new DateTime($ThatTime);
if ($dateTime->diff(new DateTime)->format('%R') == '+') {
  echo "OK";
}
