How to Determine Temporal Boundaries in PHP Using Date and Time Objects?

Determining Temporal Boundaries in PHP

In this programming scenario, we're tasked with ascertaining whether a given time falls within a predefined range. Specifically, we're given three time strings: the current time, sunrise, and sunset. Our objective is to determine if the current time lies between the boundary times of sunrise and sunset.

To tackle this challenge, we'll employ the DateTime class. This class enables us to represent and manipulate dates and times. We'll create three DateTime objects: one for the current time, one for sunrise, and one for sunset.

<code class="php">$current_time = "10:59 pm";
$sunrise = "5:42 am";
$sunset = "6:26 pm";

$date1 = DateTime::createFromFormat('h:i a', $current_time);
$date2 = DateTime::createFromFormat('h:i a', $sunrise);
$date3 = DateTime::createFromFormat('h:i a', $sunset);</code>

Now, we can compare the three DateTime objects to determine their temporal relationships.

<code class="php">if ($date1 > $date2 && $date1 < $date3) {
    echo 'The current time is between sunrise and sunset.';
}</code>
Copy after login

If the condition is satisfied, it indicates that the current time lies between sunrise and sunset. Conversely, if the condition is not met, then the current time is not within the specified range.

This approach allows us to check if a time falls within a given interval, making it applicable to various scenarios where temporal comparisons are required.
