How can PHP functions like rawurlencode() or serialize() be utilized to handle text formatting and line breaks in .txt files when reading and displaying news entries?

When reading and displaying news entries from .txt files, PHP functions like rawurlencode() can be used to encode special characters in the text, while serialize() can be used to store and retrieve formatted text with line breaks intact. By using these functions, the text formatting and line breaks in the news entries can be preserved when displaying them on a webpage.

// Read the contents of the news entry file
$news_entry = file_get_contents('news_entry.txt');

// Encode special characters in the text
$encoded_news_entry = rawurlencode($news_entry);

// Store the formatted text with line breaks intact
$serialized_news_entry = serialize($encoded_news_entry);

// Display the news entry with preserved formatting
echo urldecode(unserialize($serialized_news_entry));
