code challenge - stuck foreach loops

So am doing great all of the sudden Bummer. The second question wanted to echo each foreach loop to the screen and i thought have done already.

The error stated he can't find semi-colon.

index.php 
<?php 
$names = array('Mike', 'Chris', 'Jane', 'Bob');

?>

<pre>
  <ul>
    <?php
      foreach ( $names as $names ){
    ?>
      <li><a href=''><span class='<?php echo $names ?>'></span></a></li>
    <?php   
      }
    ?>
  </ul>
</pre>

<?php 
$names = array('Mike', 'Chris', 'Jane', 'Bob');

?>

<pre>
  <ul>
    <?php
      foreach ( $names as $name ){
    ?>
      <li><a href=''><span class='<?php echo $name; ?>'></span></a></li>
    <?php   
      }
    ?>
  </ul>
</pre>

So close! You forgot the semi colon after names (which should be name)

Also ensure you are looping over every name in names

Almost! After that, he'll just need to change $names to $name in the echo statement, as well as in the foreach. :)

I took your code and made these three modifications to get it to pass:

  1. Change it to foreach ($names as $name)
  2. Change $names to $name in your echo statement as well.
  3. Add a semicolon after 'echo $name;'

Final code:

<?php 
$names = array('Mike', 'Chris', 'Jane', 'Bob');

?>

<pre>
  <ul>
    <?php
      foreach ( $names as $name ){
    ?>
      <li><a href=''><span class='<?php echo $name; ?>'></span></a></li>
    <?php   
      }
    ?>
  </ul>
</pre>

your almost there it should be like this, $names as $name and remember to end your echo with a semicolon. I don't know how to make the code appear inline.

<?php $names = array('Mike', 'Chris', 'Jane', 'Bob');

?>

<pre> <ul> <?php foreach ( $names as $name ){ ?> <li><a href=''><span class='<?php echo $name; ?>'></span></a></li> <?php
} ?> </ul> </pre>

oh bugger... but how did that come about. what is the purpose of the semi-colon after the name, although i suppose is to differentiate the $names. but he didn't use the semi-colon himself in the lesson. see below

<ul class="social"> <?php /// Foreach loop exercise foreach($social_icons as $icon){ ?> <li><a href=""><span class="icon <?php echo $icon ?>"></span></a></li> <?php } ?> </ul>

can explain different does it makes.

he wasn't echoing something he changed the class of the object using an array. When echoing you do need a ;
