How can proper error handling be implemented when working with file functions in PHP to prevent issues like Read Error?

When working with file functions in PHP, proper error handling can be implemented by using functions like `file_exists()` and `is_readable()` to check if the file exists and is readable before attempting to read from it. Additionally, using `try-catch` blocks when opening files can help catch exceptions and prevent issues like Read Error. 

$file = 'example.txt';

if (file_exists($file) && is_readable($file)) {
    try {
        $content = file_get_contents($file);
        echo $content;
    } catch (Exception $e) {
        echo 'Error reading file: ' . $e->getMessage();
    }
} else {
    echo 'File does not exist or is not readable.';
}
