What are some best practices for handling errors in PHP, especially when dealing with functions like mkdir()?

When handling errors in PHP, especially when dealing with functions like mkdir(), it is important to check for errors and handle them gracefully to prevent unexpected behavior or security vulnerabilities. One common practice is to use error handling functions like try-catch blocks or checking the return value of the function for errors. Additionally, using appropriate error reporting settings and logging errors can help in debugging and resolving issues efficiently. 

// Example of handling errors when using mkdir()

$dir = 'new_directory';

if (!is_dir($dir)) {
    if (!mkdir($dir)) {
        // Handle error gracefully
        echo 'Failed to create directory';
        // Log the error for debugging purposes
        error_log('Failed to create directory: ' . $dir);
    }
}
