Collections

Collection is a basic data structure in programming. In traditional PHP programming, array is used widely to represent collection data structure. A PHP array is a mix of cardinal-indxed array and hash table.

In traditional PHP programm To enable object-oriented manipulation of collections, PRADO provides a set of powerful collection classes. Among them, the TList and TMap are the most fundamental and usually serve as the base classes for other collection classes. Since many PRADO components have properties that are of collection type, it is very important for developers to master the usage of PRADO collection classes.

    Extending TList

    Often, we want to extend TList to perform additional operations for each addition or removal of an item. The only methods that the child class needs to override are insertAt() and removeAt(). For example, to ensure the list only contains items that are of TControl type, we can override insertAt() as follows,
