Get total count of blog posts using MySQLi Prepared Statements

In this post, we will create a PHP script that connects to a MySQL database and retrieves the total number of blog posts from a specified table. We will utilize MySQLi prepared statements to ensure secure and efficient database interactions.

<?php
// Database configuration
$host = 'localhost';
$username = 'your_username';
$password = 'your_password';
$database = 'your_database';

// Create a connection
$conn = new mysqli($host, $username, $password, $database);

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

// Prepare the SQL statement
$sql = "SELECT COUNT(*) AS total_posts FROM blogs";
$stmt = $conn->prepare($sql);

// Execute the statement
$stmt->execute();

// Bind the result
$stmt->bind_result($total_posts);

// Fetch the result
$stmt->fetch();

// Display the total number of blog posts
echo "Total number of blog posts: " . $total_posts;

$stmt->close(); // Close the statement. There is no need to close the connection because PHP automatically does this.
?>

In the provided PHP script, we follow a structured approach to connect to a MySQL database and retrieve the count of blog posts. Here’s a breakdown of the code:

  1. Database Configuration: We start by defining the database connection parameters, including the host, username, password, and database name. Make sure to replace these placeholders with your actual database credentials.
  2. Creating a Connection: We establish a connection to the MySQL database using the mysqli class. If the connection fails, an error message is displayed, and the script terminates.
  3. Preparing the SQL Statement: We prepare an SQL query to count the total number of entries in the blogs table. Using prepared statements helps prevent SQL injection attacks, enhancing security.
  4. Executing the Statement: The prepared statement is executed, which runs the SQL query against the database.
  5. Binding the Result: We bind the result of the query to a variable ($total_posts) that will hold the count of blog posts.
  6. Fetching the Result: The fetch() method retrieves the result from the executed statement, allowing us to access the total number of blog posts.
  7. Displaying the Result: Finally, we output the total number of blog posts to the user.
  8. Closing Resources: It is essential to close the prepared statement and the database connection to free up resources.

This script provides a clear and efficient way to count blog posts in a database while adhering to best practices in PHP programming.
