    echo $stringOne;

    $strong3="testing the escape characters  $100 's  \n  $stringOne ";nippet it doesn't show on new line

It most likely does work correctly. However, if you're viewing the result in a browser, it will be interpreted as HTML, and HTML treats newlines in text just like spaces, so you won't see those newlines outside of the page source code.

If you want a line break in HTML, you'll need to use a <br> element. They can be used like this:

$stringOne = "This is what the <br>\n escape characters are <br>\n in it";
echo $stringOne;

You can also make PHP add <br> elements for you with the nl2br function, e.g.:

$stringOne = "This is what the \n escape characters are \n in it";
echo nl2br($stringOne);

Another option in HTML is to put your text inside a <pre> element, which makes the browser show newlines and other spaces as they appear in the source code. For example:

$stringOne = "<pre>This is what the \n escape characters are \n in it</pre>";
echo $stringOne;

If your output isn't intended as HTML and you actually meant it as plain text, you need to tell the browser that with header('Content-Type: plain/text,charset=UTF-8'); at the top of your PHP script:

<?php
header('Content-Type: plain/text,charset=UTF-8');
$stringOne = "This is what the \n escape characters are \n in it";
echo $stringOne;
