How to Check if the Current Date and Time Have Passed a Specific Date and Time in PHP?

Checking Past Dates and Times Using PHP's Date Function

To determine if the current date and time surpasses a set reference point, PHP offers a comprehensive set of capabilities through its date() function. This article demonstrates how to leverage these capabilities for a common scenario.

Example Scenario:

You seek a PHP script that verifies if the present date and time have progressed beyond May 15, 2010, at 4:00 PM.

PHP Solution Using DateTime:

PHP's DateTime class empowers you with granular control over date and time manipulation. Consider the following code snippet:

<code class="php">if (new DateTime() > new DateTime("2010-05-15 16:00:00")) {
    # current time is greater than 2010-05-15 16:00:00
    # in other words, 2010-05-15 16:00:00 has passed
}</code>

In this code:

• The new DateTime() expression instantiates a DateTime object representing the current date and time.
• The new DateTime("2010-05-15 16:00:00") expression creates a DateTime object for the reference date and time (May 15, 2010, at 4:00 PM).
• The comparison operator (>) determines if the current time is greater than the reference time. If so, it signifies that the reference time has passed.

By utilizing this approach, you can effectively check if the current date and time have exceeded a predetermined point in the past.
