Have a look here (the main manual is down this second) :
http://uk.php.net/manual/en/language.types.string.php
An example use is as follows :
<?php
echo "<table>\n";
echo "\t<tr>\n";
echo "\t\t<td>hi</td>\n";
echo "\t</tr>";
echo "</table>\n";
?>
The HTML source will look like :
<table>
<tr>
<td>hi</td>
</tr>
</table>
But if NO \n's or \t's were used, the HTML source would have looked like :
<table><tr><td>hi</td></tr></table>
It makes for pretty HTML source huh? Granted with the above example
we'd write it as plain HTML but it's an example :) Also such whitespace
is important when sending mail. Also, some related information exists
around here :
http://www.php.net/manual/en/function.nl2br.php

Escape quotes as you need them. In the above case I'd probably either
just write it as HTML or do this :
echo '<img src="test.gif" alt="Test Image">';
Single quotes can be in double, double can be in single. In this case
single quotes are better as PHP doesn't have to interpet anything within
single quotes, they're faster! Check out this tutorial for useful advice
on using strings (and quotes) :
