I thought that this usage indicated that the actual global variable declaration was done somewhere else, and the only way to use the global from inside your class/method block was to mention it via the "global" command, almost like it really meant "import $MyGlobal". So, my understanding was the variable is being declared/set elsewhere, and is only being imported into the class/method block via the "global" command. How does -> global $MyGlobal; differ from -> global $GLOBALS['MyGlobal']; in this scenario? Is there a danger that you've inadvertently redeclared $MyGlobal somewhere in your local code, not intending for it to replace $GLOBALS['MyGlobal'], meaning it's possible that both could exist separately?

the main problem is the definition of the variable. but i also think there is potential issues when importing the variable. i do not remember exactly, because i moved to using $GLOBALS everywhere long ago. regards, Lukas
