[15:53:08] <Krinkle>	 SMalyshev: curious if maybe you know why inside "" this undefined access yields a different value and no warning? https://3v4l.org/ASDmG 
[17:22:10] <bpirkle>	 Krinkle: http://us3.php.net/manual/en/language.types.string.php#120414  The official example on that page uses non-quoted associative array access (search for "koolaid1"), but without explanation.  I wasn't aware of this subtlety either.  On outputting a different value, the boolean true value will first be converted to the string "1" as part of variable expansion then var_dump will output that string.
[17:22:42] <Krinkle>	 bpirkle: Ah, right, I forgot (string)true is "1" in PHP.
[17:22:48] <Krinkle>	 It's "true" in JavaScript.
[17:23:00] <Krinkle>	 That makes more sense.
[17:23:41] <Krinkle>	 Thanks!
[17:23:53] <bpirkle>	 Sure thing - I learned something too!
