Everyone, sorry to bother you with this, turns out I've been doing too
much programming in true functional languages, which PHP is not, and I
had some code which I thought was ok, but some how combined with a
call to json_decode caused PHP to crash. I was basically doing
something like:
function round_datetime(Zend_Date &$datetime) {
$tmp = clone $datetime;
$tmp->set(0, Zend_Date::SECOND);
$tmp->set($tmp->get(Zend_Date::MINUTE)<30?0:30, Zend_Date::MINUTE);
return $tmp;
}
To zero-out the seconds portion of a Zend_Date object and fix the
minutes to 0 or 30. I would then do something like:
public function fooAction() {
$now = new Zend_Date();
$min = round_datetime($now)->get('yyyy-MM-dd');
// ...
// Get JSON from API server using generated time above
// ...
json_decode($jsonString);
}
Now, since this worked without the json_decode call, I was under the
impression that the error was with json_decode, not my weird datetime
function. Well, I have removed the datetime function, and now
everything works. All of this has been very weird, because I don't see
how round_datetime + json_decode interacted in a way to crash PHP.
Perhaps some Zend people could provide a perspective?
Thanks for all help.
