How can changing the date format using mktime() help in querying data in PHP?

When querying data in PHP, it is often necessary to compare dates or perform date-related operations. However, dates stored in databases or received from external sources may be in different formats. By using the mktime() function in PHP, we can convert dates from various formats into a Unix timestamp, which is a standardized format for dates and times. This allows for easier comparison and manipulation of dates in PHP queries. 

// Example of changing date format using mktime() for querying data in PHP

$dateString = "2022-10-15"; // Date in YYYY-MM-DD format
$timestamp = mktime(0, 0, 0, 10, 15, 2022); // Convert date to Unix timestamp

// Now $timestamp can be used in queries for comparing dates
$query = "SELECT * FROM table WHERE date_column >= $timestamp";
// Execute query and fetch results
