Are there any potential pitfalls to be aware of when deleting SQL data based on date in PHP?

When deleting SQL data based on date in PHP, one potential pitfall to be aware of is the risk of accidentally deleting more data than intended if the date comparison logic is not implemented correctly. To avoid this, it is important to carefully construct the SQL query to ensure that only the desired data is deleted. 

<?php
// Connect to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Define the date to use for deletion
$date = "2022-01-01";

// Construct the SQL query to delete data based on date
$sql = "DELETE FROM table_name WHERE date_column < '$date'";

// Execute the query
if ($conn->query($sql) === TRUE) {
    echo "Data deleted successfully";
} else {
    echo "Error deleting data: " . $conn->error;
}

// Close the connection
$conn->close();
?>
