How can PHP developers effectively delete specific entries from a database based on unique identifiers like IDs?

To delete specific entries from a database based on unique identifiers like IDs, PHP developers can use SQL queries with the DELETE statement. By specifying the unique identifier in the WHERE clause of the query, developers can target and delete the specific entry from the database. 

<?php
// Connect to the 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);
}

// Define the unique identifier
$id = 123;

// Prepare and execute the SQL query to delete the specific entry
$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();
?>
