''' <?php $names = array('Mike', 'Chris', 'Jane', 'Bob'); foreach ($names as $names) { echo $names; } ?> '''

echo $names;

why is this not working?

index.php 
<?php 
$names = array('Mike', 'Chris', 'Jane', 'Bob');
foreach ($names as $names) {
    echo $names; 
}
?>

Because $names is the name of the array, you can't use $names again for the items in the array. They need their own variable name. And that's what we're going to echo back to the screen. Take a look:

<?php 
$names = array('Mike', 'Chris', 'Jane', 'Bob');
foreach ($names as $name) {
    echo $name; 
}
?>

edited for clarification

What we're saying here is that our list of names is named $names. Every item in there is a $name. Mike is a name. Chris is a name etc. But $names is the list holding our names. Hope that makes sense! :thumbsup:
