Creating the Catalog array - echo & carnation question

Hey, we created an array in the catalog.php folder:

<?php $catalog = array( "Design Patterns", "Forrest Gump", "Beethoven" );

and then moved on to to echo the code with the following:

<?php foreach($catalog as $item) { echo "<li>" . $item . "</li">"; } ?>

I didn't understand how to include the li's inside the code and what the "." should display !

Hope, that someone is able to clarify this.

You've done everthig correct except one small thing, additional double quotes inside of the double quotes. If you are putting same quotes inside of the same quotes than you should escape them like this:

echo "some text \" inside of some text\"";

dot sign inside of echo statement means string concatenation, it's a part of php language(and you wont see them in output). In code below you are adding text(which you receive from array) into <li></li>(list items). So, when you render the page you'll receive this output:

<li>Design Patterns</li>
<li>Forrest Gump</li>
<li>Beethoven</li>

Working code:

$catalog = array( "Design Patterns", "Forrest Gump", "Beethoven" );

foreach($catalog as $item) {
    echo "<li>" . $item . "</li>";
}

Hope this explains how thing works ;)

you could also use...

echo "<li>$item</li>";
