Which special characters need to escape in Double-Quoted Stings?

Submitted by: Administrator
There are two special characters you need to escape in a double-quote string: the double quote (") and the back slash (). Here is a PHP script example of double-quoted strings:

<?php
echo "Hello world!";
echo "Tom said: "Who's there?"";
echo " represents an operator.";
?>
This script will print:
Hello world!Tom said: "Who's there?" represents an operator.
