Fields with a plus

[Rob Waterson]

I feel like this might be a dumb question but I cannot figure it out.
I am getting some of the non-standard fields back with a plus but when
I try to de-reference them I do not get anything out. For example, the
GA legislator data has a field called +city but if I try $leg[+city],
I get nothing. Am I being obtuse here? Do I need to strip out pluses
or something at some point?

Thanks in advance,

Rob

Sorry, in case it was not clear, this is in PHP.

Hi Rob,

It's been a long time since I've used PHP, are you using whatever
JSON-parsing it has natively or are you using some library? That is
the most likely culprit.

Hi Rob,

From php's json_decode manual page: http://php.net/manual/en/function.json-decode.php#example-3320

"Accessing elements within an object that contain characters not
permitted under PHP's naming convention (e.g. the hyphen) can be
accomplished by encapsulating the element name within braces and the
apostrophe."

<?php

$json = '{"foo-bar": 12345}';

$obj = json_decode($json);
print $obj->{'foo-bar'}; // 12345

?>

Similarly, $leg->{"+city"} should de-reference correctly.

hth,

Shane
