Creating the Product Array

Can anyone tell me why we can break up the php code when mingling it with html?

In this lesson, we create a foreach function with one { and then add our <li> tag only to finish off the php and the last } later. How does the browser or server know to connect the curly braces or that they go together? This just seems counter intuitive so I'm not sure how to know when I can break up the curly braces and when I can't in the future.

Thanks!

If you want to use PHP in HTML steven schwerin , all you need to do is <?php ?>.

I'll use WordPress as an example. The following code get's the url of the template directory, where all the files are stored and then locates a particular file. Used in this instance for getting an additional stylesheet. 

<link href="<?php bloginfo('template_directory'); ?>/css/additionalstylesheet.css">

See how, if you want to use PHP, you just put the PHP in PHP tags instead of writing out the HTML?

Hmm, I need to think about that example. I do see how you just enter it which is nice. I still don't see how or why we would separate the curly braces of a function as in this video. I guess I am asking how the browser or server knows that the curly braces are part of the same function if this is how we format the php; the braces are in different php tags.

Thank you for your response.

I thought I would go find the code.

<? php foreach($products as $products> { ?> <li><?php echo $products; ?></li> <? php } />

Do you see how the curly braces are separated in different php elements? I think this code is very useful, so I want to be able to know how to recreate it in different situations.
