Handle Array Structure in php gtk

In this post, we display a tree structure from array in php gtk, for do this please follow below points:

1.) Sets up the treestore to store the data. Here it sets three fields. The first one is integer that stores the id. The second and third are strings.

2.) Creates a GtkTreeview. It is here that you bind the model to the treeview.

3.) Sets up the treeview columns.

4.) Loops through the data list and appends the data one by by to the tree structure. Note that $nodes stores the GtkTreeiter of each node. You can view this as a pointer to the node.
