PHP: Newline \n is not working

At this point, PHP is only creating the source code of the HTML document. When you have look at the source code in the browser, you should see the created line break in the code.

In the browser itself, you can see nothing of it, since only HTML tags such as <br>, <p> and so forth are producing a new line in the browser.

In the source code, the line breaks are only usable for convenience purposes, therefore a \n in PHP code has only the function to make the source code easier to read. Exactly the same effect has a line break created by using the enter key in your source code editor.

In JavaScript, it is a bit different. There is not such a distinction between source code and strings. Here, a \n directly becomes a "visible" line break, for example, used within a dialog box, created by the function alert().
