What best practices can be employed to prevent SQL syntax errors when constructing and executing DELETE queries in PHP?

To prevent SQL syntax errors when constructing and executing DELETE queries in PHP, it is recommended to use prepared statements with placeholders for variables to avoid SQL injection attacks and ensure proper escaping of user input. Additionally, double-check the syntax of the DELETE query to ensure it is correct before executing it. 

// Example of using prepared statements to prevent SQL syntax errors in DELETE query

// Establish a database connection
$pdo = new PDO('mysql:host=localhost;dbname=database_name', 'username', 'password');

// Prepare the DELETE query with a placeholder for the variable
$stmt = $pdo->prepare("DELETE FROM table_name WHERE column_name = :value");

// Bind the variable to the placeholder
$value = "example_value";
$stmt->bindParam(':value', $value);

// Execute the query
$stmt->execute();
