How can PHP developers efficiently identify and fix SQL syntax errors in their code?

To efficiently identify and fix SQL syntax errors in PHP code, developers can utilize error reporting functions like `mysqli_error()` or `PDO::errorInfo()` to get detailed error messages. They should carefully review the SQL query strings for any syntax mistakes, such as missing quotes or incorrect keywords. Additionally, using prepared statements with placeholders can help prevent SQL injection attacks and make debugging easier. 

// Example code snippet demonstrating how to use error reporting and prepared statements to identify and fix SQL syntax errors

// Create a connection to the database
$pdo = new PDO("mysql:host=localhost;dbname=mydatabase", "username", "password");

// Prepare a SQL query with placeholders
$stmt = $pdo->prepare("SELECT * FROM users WHERE id = :id");

// Bind parameter values to the placeholders
$stmt->bindParam(':id', $userId, PDO::PARAM_INT);

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

// Check for errors
if($stmt->errorCode() !== '00000') {
    echo "SQL error: " . $stmt->errorInfo()[2];
}
