Are there best practices for using DATE_FORMAT in the WHERE clause of a SQL query in PHP?

When using DATE_FORMAT in the WHERE clause of a SQL query in PHP, it is important to remember that the date format specified in DATE_FORMAT should match the format of the date column in the database. Additionally, it is recommended to use parameterized queries to prevent SQL injection attacks. Example PHP code snippet: 

<?php
// Assuming $conn is the database connection

$date = '2022-01-01';
$formatted_date = date('Y-m-d', strtotime($date)); // Format the date as needed

$stmt = $conn->prepare("SELECT * FROM table_name WHERE DATE_FORMAT(date_column, '%Y-%m-%d') = ?");
$stmt->bind_param("s", $formatted_date);
$stmt->execute();
$result = $stmt->get_result();

while($row = $result->fetch_assoc()) {
    // Process the results
}

$stmt->close();
$conn->close();
?>
