Are there any specific functions or methods in PHP that can help with encoding and decoding text files?

When working with text files in PHP, it may be necessary to encode or decode the content for various reasons such as security or data manipulation. PHP provides built-in functions for encoding and decoding text files, such as base64_encode() and base64_decode(). These functions can be used to convert text files into a format that is safe for transmission or storage, and then decode them back to their original form when needed. 

// Encoding a text file using base64_encode()
$fileContent = file_get_contents('example.txt');
$encodedContent = base64_encode($fileContent);

// Decoding a text file using base64_decode()
$decodedContent = base64_decode($encodedContent);

// Saving the decoded content back to a file
file_put_contents('decoded_example.txt', $decodedContent);
