Why can I add named properties to an array as if it were an object?
...ry properties on it. This should be considered harmful though. Arrays are for numerically indexed data - for non-numeric keys, use an Object.
Here's a more concrete example why non-numeric keys don't "fit" an Array:
var myArray = Array();
myArray['A'] = "Athens";
myArray['B'] = "Berlin";

How to get body of a POST in php?
...
To access the entity body of a POST or PUT request (or any other HTTP method):
$entityBody = file_get_contents('php://input');
Also, the STDIN constant is an already-open stream to php://input, so you can alternatively do:
$entityBody = stream_get_contents(...
Return string without trailing slash
... str.length - 1);
}
return str;
}
Note: IE8 and older do not support negative substr offsets. Use str.length - 1 instead if you need to support those ancient browsers.
