How can PHP developers troubleshoot and debug SQL errors effectively when integrating SQL queries into their code?

To troubleshoot and debug SQL errors effectively when integrating SQL queries into their code, PHP developers can use error handling techniques such as try-catch blocks to catch and display any SQL errors that may occur. They can also utilize tools like PHP's mysqli_error() function to retrieve detailed error messages from the database server. 

// Example code snippet demonstrating the use of try-catch blocks for error handling in PHP
try {
    $conn = new mysqli($servername, $username, $password, $dbname);
    // Check connection
    if ($conn->connect_error) {
        throw new Exception("Connection failed: " . $conn->connect_error);
    }

    // SQL query
    $sql = "SELECT * FROM users";
    $result = $conn->query($sql);

    if ($result === false) {
        throw new Exception("Error executing query: " . $conn->error);
    }

    // Process query results
    // ...

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