In the code snippet provided, what is the purpose of replacing '\r' and '\n' with specific characters in the text variable before outputting to the Excel file?

The purpose of replacing '\r' and '\n' with specific characters in the text variable before outputting to the Excel file is to ensure that the line breaks are preserved correctly in the Excel file. Excel may not interpret '\r' and '\n' as line breaks, so replacing them with specific characters like '<br>' can help maintain the formatting when the data is displayed in Excel. 

// Original text with line breaks
$text = &quot;Hello\r\nWorld&quot;;

// Replace &#039;\r&#039; and &#039;\n&#039; with &#039;&lt;br&gt;&#039;
$text = str_replace([&quot;\r&quot;, &quot;\n&quot;], &quot;&lt;br&gt;&quot;, $text);

// Output the modified text to the Excel file
// (Code to output to Excel file goes here)
