newline \n and tab \t Not Working in PHP 5.0.3 | Apache 2.0.52 | Windows XP Pro

The following examples (see PHP 5 for Dummies, p. 82)
do not produce the expected results:

$string = "Hello \nWorld";
echo $string;

and

$string = "Line 1 \n\tLine 2";
echo $string;

The first instance is for a line break such that the words are stacked:

Hello
World

The second instance is for a line break with a tabbed second line:

Line 1
Line 2

Do I need to change or add something in one of the configuration files?
Otherwise, is there a known fix for this? Thank you for any assistance.

Newlines and tabs are ignored by browsers when rendering HTML. If you
view the source of the page in your browser you will see the tabs and
newline breaks are there.

To do a line break in HTML you need to use the <br /> tag, or enclose
your sentance in <p> and </p> tags.

I noticed that Message-ID:

I'd be interested to see what the book actually says the code does...

The book says the code should produce the two results shown in my
original post (which are copied there from the book). These expected
results appear below the examples in my post, a little farther down in
its text, as "first instance" and "second instance"--i.e., the first
result is to provide a line break (newline \n), and the second result
is to provide both a line break and a tab (newline tab n\t\).

It should provide the expected results when you use View Source to see
the raw HTML code. However, when the browser displays the page it will
ignore the extra whitespace (spaces, tabs, and newlines are all whitespace).

Thank you.

It seems that the usefulness of the \n and \t features is limited to
formatting source code for easy readability.

It looks like <p></p> tags would be the best choice for onscreen
formatting. I imagine using CSS classes in them would permit such
things as the equivalent of tabbing, in addition to the default line
breaks.

Since browsers collapse all consecutive whitespace to a single space by
default, you could do this:

echo '<pre>';
echo $string;
echo '</pre>';

If you are expecting plain text output, add this to the very beginning of
the file:

header('Content-Type: text/plain');
