It's attribution _line_, not attribution novel. And you better get a real
name.

Yes, it is not; read more carefully. What you call "excessive" I call the
minimum necessary to retain the context; the other parts have been replaced
by ellipsises (as it is customary and considered polite when omitting text
in quotations).
The purpose of it was to show that my suggestion, json_encode(), actually
provides what the OP asked for –
| […] JavaScript object which looks like
|
| {
|
| 'abc' : '1 AND (2 OR 3)'
| }
– as associative PHP arrays are (and must be) converted to ECMAScript
Object-literal-compatible JSON values (since ECMAScript implementations like
JavaScript have no built-in notion of associative arrays), whereas
(numerically) indexed PHP arrays are converted to Array-literal-compatible
JSON values. The latter is exactly what the OP asked for when they wrote
| […] to convert
|
| array('marketing_campaign_id', 'status', 'status')
|
| into equivalent JavaScript.
which is
["marketing_campaign_id", "status", "status"]
I do not know what "sheldonlg"'s and Jerry Stuckle's gripe is with this
solution, but until they come up with something substantial, I will just
ignore it.
I am using json_encode() in production environments to make Web applications
more responsive, and I have not noticed any problems beyond those that PHP
has with character encoding in the first place – for example, you have to do
<?php
echo json_encode(array('foo' => 'ba' . utf8_encode(chr(0xA0)) . 'r'));
?>
to get the equivalent
{"foo":"ba\u00a0r"}
since
<?php
echo json_encode(array('foo' => 'ba' . chr(0xA0) . 'r'));
?>
will result in a UTF-8 warning and
{"foo":null}
