echo中的PHP数组

Question

I have an assignment to do but am having trouble understanding the given psuedocode :/

<?php
$bucket = new array();
print $bucket->addrocks('Rock1')->addrocks('rock2')-
>addrocks('Rock3');

echo "<h1>My Bucket</h1>";
echo "<ul>";
foreach($bucket as $rock){
echo "<li>". $rock ."</li>";
}
echo "</ul>";
?>

Now my trouble starts with understanding how they want me to construct the array after the "print" call? i am not looking for a direct answer to this just maybe a tutorial link or a finger in the right direction

Thank you in advance

In PHP, new is only used for instantiating objects Furthermore, array is a reserved word in PHP, so name your class something else. To instantiate an array in PHP you do this:

 $my_array = array();

Now to add items to the array you would do this:

 $my_array[] = "Rock 1";
 $my_array[] = "Rock 2";
 $my_array[] = "Rock 3";

To traverse the array you can use any type of loop, but usually you would just use a foreach loop.

For example:

 foreach($my_array as $key => $value) {
   echo $value . "<br />";
 }
