What is the best way to count and display the number of records in a database table based on a specific year using PHP?

To count and display the number of records in a database table based on a specific year using PHP, you can execute a SQL query that counts the number of records with a date column that falls within the specified year. You can then fetch the count result and display it on the webpage. 

<?php
// Connect to 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 year
$year = 2022;

// SQL query to count records based on specific year
$sql = "SELECT COUNT(*) as count FROM table_name WHERE YEAR(date_column) = $year";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // Output data of each row
    while($row = $result->fetch_assoc()) {
        echo "Number of records in $year: " . $row["count"];
    }
} else {
    echo "0 results";
}

$conn->close();
?>
