What's Wrong With This Code?

Treehouse Community rocks! Can you help me on this one. I think I'm close :-)

plugin.php 
<?php

/*
  {
    "name": "Username",
    "profile_name": "profile_username",
    "profile_url": "http://myapi.net/profile_username"
    "courses": [
      { "name": "WordPress Plugin Development" },
      { "name": "WordPress Theme Development" },
      { "name": "Introduction to PHP" }
    ]
  }
*/

?>

<ul>
  <?php for( $i = 0; $i < count($my_plugin_profile->courses); $i++ ): ?> {

  <?php echo $plugin_profile->{'courses'}[$i]->{'names'}; ?>
  }

  <?php endfor; ?>
</ul>

There's a few issues with your code.

  1. There's no need to have the curly braces where you have them. In that setup they would just be displayed as is and would not be doing anything.
  2. You are using $plugin_profile as your variable when it is actually $my_plugin_profile, so you are referencing the wrong variable.
  3. The challenge wants you to output each course name within a list item element, you can do this by echoing out the opening and closing li tags and concatenate them with the rest of your code.
  4. You are referencing the course names as "names" instead of "name"
 <?php echo '<li>'.$my_plugin_profile->{"courses"}[$i]->{"name"}.'</li>'; ?>

Thanks! I tried:

<ul>
  <?php for( $i = 0; $i < count($my_plugin_profile->courses); $i++ ): ?> 

     <li><? echo $my_plugin_profile->courses[$i]->name; ?></li>

  <?php endfor; ?>
</ul>

Witch did not work in the challenge, but works in "real" code.
