Developer's Guide :: List Arrays
In Delphi for Win32, there is a class named TList, in RPCL, the equivalent is called Collection, which is a class that provides a way to handle a list of "things", as they can contain almost anything. Collections are wrappers to PHP arrays, so in some cases, a pure PHP array will be the best option for speed sake.
In PHP, arrays are really powerful, and there is a lot of built-in functions to handle arrays, so Collection class has been provided to ease the path to PHP, but in most cases, an array is enough.
Collections in the RPCL provide the following methods:
integer add( object $item) // Add an item to the list // object $item Object to add to the list void clear( ) // Clears the list integer count( ) // Return the number of items in the list void delete( integer $index) // Delete an item from the list by its index // integer $index Index of the item to delete void indexof( object $item) // Finds an item into the list // object $item Item to find object last( ) // Return the last element from the collection void remove( object $item) // Remove an item from the list // object $item Item to delete from the list
