What steps should be taken to verify the consistency of server-side scripts and data to troubleshoot issues related to SQL syntax errors in PHP?

To verify the consistency of server-side scripts and data to troubleshoot issues related to SQL syntax errors in PHP, you should first check the SQL queries in your PHP code for any syntax errors or inconsistencies. Make sure that the data being passed to the queries is properly sanitized and formatted to prevent SQL injection attacks. Additionally, you can use error handling techniques such as try-catch blocks to catch and handle any SQL syntax errors that may occur during the execution of your PHP scripts. 

// Example PHP code snippet to verify SQL syntax and handle errors
try {
    $conn = new PDO("mysql:host=localhost;dbname=myDB", $username, $password);
    $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

    $stmt = $conn->prepare("SELECT * FROM users WHERE id = :id");
    $stmt->bindParam(':id', $id, PDO::PARAM_INT);
    $stmt->execute();

    $result = $stmt->fetchAll(PDO::FETCH_ASSOC);
    print_r($result);

} catch (PDOException $e) {
    echo "Error: " . $e->getMessage();
}
