What is the common issue with line breaks when retrieving data from a database in PHP?

When retrieving data from a database in PHP, line breaks may not be displayed correctly due to differences in line break representations between the database and the PHP environment. To solve this issue, you can use the PHP `nl2br()` function to convert newline characters to HTML line breaks `<br>` before displaying the data on a webpage.

// Retrieve data from the database
$data = $row[&#039;content&#039;];

// Convert newline characters to HTML line breaks
$data_with_line_breaks = nl2br($data);

// Display the data with line breaks on a webpage
echo $data_with_line_breaks;
