How to Determine if a Time Falls within a Range in PHP?

Determining if a Time Falls within a Specified Range in PHP

In PHP, you may encounter the need to ascertain whether a given time falls within a specific range, such as between sunrise and sunset. To effectively resolve this issue, follow the steps outlined below:

  1. Convert Time Strings to Datetime Objects:
    Convert your time strings ($current_time, $sunrise, and $sunset) into DateTime objects using the DateTime::createFromFormat() function.
<code class="php">$current_time = DateTime::createFromFormat('h:i a', $current_time);
$sunrise = DateTime::createFromFormat('h:i a', $sunrise);
$sunset = DateTime::createFromFormat('h:i a', $sunset);</code>
Copy after login
  1. Compare Datetime Objects:
    Utilize the comparison operators (>, <) to determine if the current time falls within the specified range.
<code class="php">if ($current_time > $sunrise && $current_time < $sunset) {
   echo 'Time is between sunrise and sunset';
}<p>For instance, with the provided input:</p>
<pre class="brush:php;toolbar:false"><code class="php">$current_time = "4:59 pm";
$sunrise = "5:42 am";
$sunset = "6:26 pm";</code>
Copy after login

The code will output:

Time is between sunrise and sunset
Copy after login

By implementing these steps, you can determine if a given time is within a specified range in PHP.
