foreach

[agmorgan]

I am having a problem with a double foreach statment.

$food_categories = array( "Fruit" => "Apple", );

foreach($food_categories as $key => $subarray)
{
echo "<h3>$key </h3>";
echo "<ul>";

 foreach($subarray as $type)
 {
    echo "<input type='radio' name='interest' 
              value='$type'><b>$type</b><br>\n";
 }
 echo "</ul>";

}

the first statment works i.e .I get the word FRUIT appear. but the second foreach loop gives me the following and for the life of me I do not know why or what I am doing wrong..

$subarray is not an array it is just the value 'Apple' which is why your are getting the error.
