What are the potential drawbacks of not loading the file contents into a variable before base64 encoding in PHP?

If you do not load the file contents into a variable before base64 encoding in PHP, you may encounter issues with memory consumption, as the entire file will need to be loaded into memory at once. This can be problematic for large files, potentially causing performance issues or even crashing the script. To avoid this, it is recommended to read the file contents into a variable before encoding it to base64. 

// Read file contents into a variable before base64 encoding
$file_contents = file_get_contents('example.jpg');
$base64_encoded = base64_encode($file_contents);

// Use the $base64_encoded variable as needed
