How can PHP be used to automatically delete records in a MySQL database based on a specified date criteria?

To automatically delete records in a MySQL database based on a specified date criteria, you can use PHP to write a script that connects to the database, queries the records that meet the specified date criteria, and then deletes those records. 

<?php

// Connect to MySQL 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);
}

// Specify the date criteria for deletion
$date_criteria = "2022-01-01";

// Query and delete records based on the date criteria
$sql = "DELETE FROM table_name WHERE date_column < '$date_criteria'";
if ($conn->query($sql) === TRUE) {
    echo "Records deleted successfully based on the specified date criteria";
} else {
    echo "Error deleting records: " . $conn->error;
}

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

?>
