How Can I Compare DateTime Objects in PHP 5.2.8?

Comparison Operators for DateTime Objects in PHP 5.2.8

In PHP 5.2.8, the DateTime class provides a straightforward way to compare two date and time objects. Contrary to initial assumptions, there are indeed comparison operators available for this class.

The following code demonstrates how to compare two DateTime objects:

$start_dt = new DateTime(verifyParam ('start_date'));
$end_dt = new DateTime(verifyParam ('end_date'));

if ($end_dt < $start_dt) {
    // End date is more ancient than the start date
}

The comparison operators for DateTime Objects include:

• ==: Checks for equality
• !=: Checks for inequality
• <: Checks if the first object is earlier than the second
• <=: Checks if the first object is earlier than or equal to the second
• >: Checks if the first object is later than the second
• >=: Checks if the first object is later than or equal to the second
