How can including or excluding time in date comparisons impact query results in PHP?

Including or excluding time in date comparisons can impact query results in PHP because dates with different times may not be considered equal when compared. To solve this issue, it is important to standardize the format of dates by removing the time component before performing comparisons. This can be achieved by using the `DATE()` function in MySQL to extract only the date part of a datetime field. 

// Example code snippet to compare dates without considering time

// Assuming $date1 and $date2 are datetime values from the database
$date1 = date('Y-m-d', strtotime($date1));
$date2 = date('Y-m-d', strtotime($date2));

if ($date1 == $date2) {
    echo "Dates are equal";
} else {
    echo "Dates are not equal";
}
