PHP - CodeIgniter - Invalid argument supplied for foreach

Question

I'm attempting to use CodeIgniter to create a website, but PHP is giving me trouble. I'm confident that it is so obvious and cannot be flawed. But I'm new to CodeIgniter and have no idea where issues come from.

    <html>  
    <head>  
        <title><?=$page_title?></title>  
    </head>  
    <body>  
        <?php foreach($result as $row):?>  
        <h3><? echo $row->title; ?></h3>  
        <p><? echo $row->text; ?></p>  
        <?php endforeach;?>  
    </body>  
</html>

I've a bug from this file :

A PHP Error was encountered

Severity: Warning

Message: Invalid argument supplied for foreach()

Filename: views/helloworld_view.php

Line Number: 6

Can someone please help me with this?

You must pass an array as the variable to the foreach loop. With the following approach, you can omit the foreach if the value of the given variable is not an array.

<?php if(is_array($result)): ?>
<?php foreach($result as $row):?>  
<h3><? echo $row->title; ?></h3>  
<p><? echo $row->text; ?></p>  
<?php endforeach;?>  
<?php endif; ?>

I hope this helps you.
