Global variables in PHP: a solution

[Jacemdom]

From Experts-Exchange newsletter :

Global variables are a fact of life. Although global variables are technically never necessary, particularly in PHP programs that use object-oriented design, they often make programs easier to read and easier to write. There are definitely situations in which they are reasonable and appropriate: resources or handles returned from API calls that are used in many functions, frequently-used arguments passed in via GET or POST, and very long strings used in cryptological protocols are some cases that come to mind.

The problem I have with global variables in PHP is that they work the opposite way they do in other languages: they are declared in each function, instead of at file level. This is about as verbose and difficult to maintain as passing each global variable used by a function in its argument list. Argument lists (or "global" statements) become longer, and must change wherever needed when a new global variable is added to the program.

that's why I allways use objects in PHP

who needs globals, if he can access "his" variables in a proper designed "root object"?
