Method add_constant()


Method add_constant

void add_constant(string name, mixed value)
void add_constant(string name)

Description

Add a new predefined constant.

This function is often used to add builtin functions. All programs compiled after the add_constant() function has been called can access value by the name name .

If there is a constant called name already, it will be replaced by by the new definition. This will not affect already compiled programs.

Calling add_constant() without a value will remove that name from the list of constants. As with replacing, this will not affect already compiled programs.
