How to Delete Data from a PHP Database [Video Tutorial]81

In this tutorial, we will show you how to delete data from a MySQL database using PHP. We will use the MySQLi extension to connect to the database and execute the DELETE query.

Step 1: Connect to the Database

First, we need to connect to the MySQL database. We can use the following code to do this:```php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "databasename";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
```

Step 2: Write the DELETE Query

Once we have connected to the database, we can write the DELETE query. The DELETE query has the following syntax:```
DELETE FROM table_name
WHERE condition;
```

In our case, we want to delete the row with the ID of 1 from the "users" table. We can use the following query to do this:```
$sql = "DELETE FROM users WHERE id = 1";
```

Step 3: Execute the Query

Once we have written the query, we can execute it using the `mysqli_query()` function. The `mysqli_query()` function takes two parameters: the connection object and the query string.```php
if ($conn->query($sql) === TRUE) {
echo "Record deleted successfully";
} else {
echo "Error deleting record: " . $conn->error;
}
```

Step 4: Close the Connection

Finally, we need to close the connection to the database. We can use the `mysqli_close()` function to do this.```php
$conn->close();
```
