How can PHP developers effectively troubleshoot SQL syntax errors when deleting records in a database?

When troubleshooting SQL syntax errors when deleting records in a database, PHP developers can start by carefully reviewing the SQL query being used for any syntax errors or typos. They can also use error reporting functions in PHP to display any SQL errors that occur during the execution of the query. Additionally, developers can use prepared statements or parameterized queries to prevent SQL injection attacks and ensure the correct syntax is used. 

<?php

// Establish a connection 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);
}

// Prepare and execute the SQL query to delete a record
$id = 1;
$stmt = $conn->prepare("DELETE FROM table_name WHERE id = ?");
$stmt->bind_param("i", $id);
$stmt->execute();

// Check for errors
if ($stmt->error) {
    echo "Error: " . $stmt->error;
}

// Close the statement and connection
$stmt->close();
$conn->close();

?>
