How can PHP developers ensure that database operations, such as deletion, are successfully executed within a function called by an HTML link?

To ensure that database operations, such as deletion, are successfully executed within a function called by an HTML link, PHP developers can use AJAX to asynchronously send a request to the server without reloading the entire page. This allows the deletion operation to be processed in the background and provides immediate feedback to the user without disrupting their browsing experience. 

```php
<?php
// PHP code to handle deletion operation

if(isset($_POST['id'])){
    // Connect to database
    $conn = new mysqli('localhost', 'username', 'password', 'database');

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

    // Get the ID of the record to be deleted
    $id = $_POST['id'];

    // Prepare and execute the SQL query to delete the record
    $sql = "DELETE FROM table_name WHERE id = $id";
    if ($conn->query($sql) === TRUE) {
        echo "Record deleted successfully";
    } else {
        echo "Error deleting record: " . $conn->error;
    }

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

This PHP code snippet demonstrates how to handle a deletion operation when receiving an AJAX request. The code connects to the database, retrieves the ID of the record to be deleted from the POST request, executes the SQL query to delete the record, and provides feedback on the success or failure of the operation.
