PHP Escape Character

<h2>Escape Character</h2>
        <p>To insert characters that are illegal in a string, use an escape character.
An escape character is a backslash \ followed by the character you want to insert.
An example of an illegal character is a double quote inside a string that is surrounded by double quotes:</p>
        <?php
            echo "We are the so-called \"Vikings\" from the north.";
        ?>
