Re: [PHP] What am I not understanding about $GLOBALS['myvar'] vsglobal $myvar?

variables inside single quotes are not evaluated! This is the same variable:
echo $GLOBALS['var'];
$key='var'; echo $GLOBALS[$key];
With $GLOBALS['$key'] you refer to an invalid variable name $'$key'

PS: Output of

echo GLOBALS['$key'] = $valuebr\n;
is right because $key is in double quotes (the outermost qoutes)

$GLOBALS[$key] is incorrect and depricated AFAIK.
$GLOBALS['$key'] (with the single quotes) is the proper way to write these
types of associative arrays/hashs.
For shits and giggles however I tried your way and it made no difference to
the code. Still didn't work right.

I did not read your whole message, but you very likely mean

$GLOBALS[$key] = ;
(no single quotes)
   

}
}
clearPostVars();
}

there is no $ in front of GLOBALS ;)

...almost... the array deref should be in curly quotes then:

echo {GLOBALS['$key']} = $valuebr\n;
