How can the entire server array be displayed using print_r($_SERVER) in PHP?

When using print_r($_SERVER) in PHP, the output may be too long to display on a single page, especially if the server array contains a lot of information. To display the entire server array in a more readable format, you can wrap the print_r function within the <pre> HTML tag. This will preserve the formatting and display the output in a more organized way. 

echo &#039;&lt;pre&gt;&#039;;
print_r($_SERVER);
echo &#039;&lt;/pre&gt;&#039;;
