Lesson 8: How to find the size of an array

Lesson 8: How to find the size of an array

In lesson 8, there is a suggestion of using the following code:

<?php
foreach ($arrFruits as $x){
echo $x
}
?>

I have uploaded it using the $fruitlist example, trying to merge the above code with the <ul> <li></il></ul> but the list appears that the fruit items are not align with the bullets. I wonder what is wrong with the position or other reasons that caused it. My link is as follows:

i think it's a bad example in lesson 8
you can get the size of array by using this method

Code: Select all

<?php
$fruits = array("apple","orange","mango");
echo count($fruits);
?>


And if you want to combine the foreach with ul and li you can do it like this

Code: Select all

<?php
$fruits = array("apple","orange","mango");
echo '<ul>';
      foreach ($fruits as $x) {
         echo '<li>'.$x.'</li>';
      }
echo '</ul>';

?>

Very Good ! I wonder why the tutorial gave us bad examples. I tried both suggestions. The count of fruits and ul.li and ol.li, all of them work perfectly. Thanks a lot ! It makes me feel more like to learn building website because of these forums.
