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

[Leif K-Brooks]

No, you misunderstand.  The key is simply a string.  Just as "print 
foo;" is wrong, $array[foo] is wrong (unless foo is a constant, of 
course).  If you do "print '$variable';", it will print the literal 
string "$variable".  It will not print the value of $variable.  You 
should either use double quotes or no quotes.

I think you either want to use no quotes or double quotes, but not single
quotes. Double quotes will interpolate the variable, single quotes will not,
i.e. $key becomes a string literal rather than a variable. No quotes will
work, although the docs seem to indicate it is deprecated syntax. Not
everyone agrees that it is deprecated, though ;)

$GLOBALS[$key] is incorrect and depricated AFAIK.
$GLOBALS['$key'] (with the single quotes) is the proper way 
to write these
types of associative arrays/hashs.
