In what scenarios would using file_get_contents be more advantageous than reading the file line by line in the code snippet?

Using file_get_contents can be more advantageous than reading a file line by line when you need to read the entire contents of a file into a single string variable. This can be useful when you want to manipulate the entire content of the file as a single entity, rather than processing it line by line. Additionally, file_get_contents simplifies the code and makes it more concise compared to reading the file line by line.

// Using file_get_contents to read the entire content of a file into a variable
$fileContents = file_get_contents('file.txt');

// Manipulate the content of the file as needed
echo strtoupper($fileContents);
