How can the user determine if the text file is being read as strings in the PHP code?

When reading a text file in PHP, it is important to ensure that the file is being read as strings. To determine if the text file is being read as strings, you can use the `is_string()` function to check if the content of the file is being treated as strings. If the content is not being read as strings, you can explicitly cast the content to a string using `(string)`. 

$file = "example.txt";
$content = file_get_contents($file);

if(is_string($content)){
    echo "File content is being read as strings.";
} else {
    $content = (string) $content;
    echo "File content is now treated as strings.";
}
