Pointers (C++ and PHP Cross Reference Guide)

By Mike Prestwood

C++ versus PHP: A side by side comparison between C++ and PHP.

 
Data Structures
 

Data structures allow you to store and work with data. Common data structures include arrays, associative arrays, etc.

Pointers

[Other Languages] 

General Info: Pointers / References

A pointer is a variable type that allows you to refer indirectly to another object. Instead of holding data, a pointer holds the address to data -- the address of another variable or object. You can change the address value a pointer points to thus changing the variable or object the pointer is pointing to.

A reference is a type of pointer that cannot change and it must always point to a valid storage (no nulls).

C++: 

C++ uses both pointers and references. Use the * operator to declare a pointer and use the & operator to declare a reference.

More Info / Comment
PHP:   Not Supported

PHP supports references which allow you to refer to the value of a variable but PHP does not support true developer defined pointers. You cannot get and use the address of a variable.

However, you can still do inexpensive assignments by assigning by reference.
