Question

I have some xml that I manually construct in a function that is something like:

$xml = "<myxml>";
$xml .= "<items>";
$xml .= "<item1>blah</item1>";
$xml .= "</items>";
$xml .= "</myxml>";

When I output the string though I’d like the newlines to be present. How can I add this to the string without affecting a web service accepting the xml? Do newlines in XML even matter?

Answer 1

The new lines aren’t required but you can use the PHP_EOL constant which is a cross platform way of finding the new line character. i.e.

$xml = "<myxml>".PHP_EOL;
