What are the best practices for handling warnings and errors when using file_get_contents in PHP?

When using file_get_contents in PHP, it is important to handle warnings and errors properly to prevent potential issues with your code. One common approach is to use the error control operator (@) to suppress warnings and errors, and then check the return value of file_get_contents to determine if the operation was successful. Additionally, you can use the file_exists function to check if the file exists before attempting to read it. 

// Suppress warnings and errors, and check if file_get_contents was successful
$content = @file_get_contents('example.txt');
if ($content === false) {
    // Handle error here
    echo 'Error reading file';
} else {
    // File read successfully, continue with processing
    echo $content;
}
