Zeta Components - high quality PHP components

The nodes in the list can be accessed through an array as this class implements the ArrayAccess SPL interface. The array is indexed based on the the node's ID.

Example:

1.  <?php
2.      // Create a list with two elements
3.      $list = new ezcTreeNodeList;
4.      $list->addNode( new ezcTreeNode( $tree, 'Leo' ) );
5.      $list->addNode( new ezcTreeNode( $tree, 'Virgo' ) );
6.  
7.      // Retrieve the list's size
8.      echo $list->size, "\n"; // prints 2
9.  
10.      // Find a node in the list
11.      $node = $list['Virgo'];
12.  
13.      // Add nodes in an alternative way
14.      $list['Libra'] = new ezcTreeNode( $tree, 'Libra' );
15.  
16.      // Remove a node from the list
17.      unset( $list['Leo'] );
18.  
19.      // Checking if a node exists
20.      if ( isset( $list['Scorpius'] ) )
21.      {
22.          // do something if it exists
23.      }
24.  
25.      // Use the associated data store to fetch the data for all nodes at once
26.      $list->fetchDataForNodes();
27.  ?>
