What are common pitfalls when using file_get_contents in PHP?

One common pitfall when using file_get_contents in PHP is not handling errors properly. If the function fails to retrieve the file contents, it will return false, which can lead to unexpected behavior in your application. To mitigate this, you should check the return value of file_get_contents and handle any potential errors accordingly, such as by using a conditional statement to handle the false return value. 

$file_contents = file_get_contents('example.txt');

if($file_contents === false) {
    // Handle error, such as logging or displaying a message
} else {
    // Proceed with using the file contents
}
