What potential issues can arise when storing text with line breaks in a MySQL database using PHP?

When storing text with line breaks in a MySQL database using PHP, the main issue that can arise is that the line breaks may not be preserved when retrieving the data from the database. To solve this issue, you can use the PHP function `nl2br()` to convert the line breaks to HTML line breaks before storing the text in the database. This way, when you retrieve the data and display it on a webpage, the line breaks will be preserved.

$text = "This is a text with line breaks. 
Line breaks should be preserved.";

$text_with_line_breaks = nl2br($text);

// Store $text_with_line_breaks in the MySQL database
