MySQL Delete Data

The Ultimate Guide to Deleting Data in MySQL with PHP

In this article, we'll go over the steps needed to delete data in a MySQL database using PHP. Whether you're looking to clean up old data or remove sensitive information, this guide has everything you need to know to get started.

Step 1: Connect to Your MySQL Database

Before you can delete any data, you'll need to connect to your MySQL database using PHP. Here's an example of how to do it:

<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database_name";

// Create connection
$conn = mysqli_connect($servername, $username, $password, $dbname);
// Check connection
if (!$conn) {
    die("Connection failed: " . mysqli_connect_error());
}

In this example, replace localhost with the name of your server, username and password with your login credentials, and database_name with the name of your database.

Step 2: Write Your DELETE Statement

Once you've connected to your database, you can start writing your DELETE statement. This is the SQL code that will actually delete the data from your database. Here's an example of a DELETE statement:

DELETE FROM table_name
WHERE column_name = value;

In this example, replace table_name with the name of your table and column_name with the name of the column you want to use to filter the data. You'll also need to replace value with the actual value you want to delete.

Step 3: Execute Your DELETE Statement with PHP

Now that you've written your DELETE statement, you can execute it using PHP. Here's an example of how to do it:

<?php
$sql = "DELETE FROM table_name WHERE column_name = value";

if (mysqli_query($conn, $sql)) {
    echo "Record deleted successfully";
} else {
    echo "Error deleting record: " . mysqli_error($conn);
}

In this example, replace table_name and column_name with the names from your DELETE statement. You'll also need to replace value with the actual value you want to delete.

Step 4: Close Your Connection

Finally, once you've executed your DELETE statement, you'll need to close your connection to the MySQL database. Here's an example of how to do it:

<?php

mysqli_close($conn);

And that's it! You've successfully deleted data from a MySQL database using PHP.
