在ExpressionEngine中更改用户定义的全局变量值

Question

Say I've got a global variable which I'm accessing inside a PHP block, which compares to a querystring... if the comparison is true I want to set the value for a global EE variable so that all the other template pages can recognise that the value is not what it normally is - is this possible, or are the global user-defined variables constants?

Thanks, Dan

You can use the PHP $GLOBAL Superglobal Array, for such cases. Say you have written a variable in any block of a particular page as $a = 123;.
Now in the same page, but in another block, you can easily change it to something else as $GLOBALS['a'] = 456;.

Hope it helps.
