Getting information out a json sting - php

Question

I am attempting to work with JSON in PHP and I was wondering if someone could help me out getting me to the $events=>$url when the information is returned from json_decode. What is the variable path. There are a number of looping record in the return data and I am using something like:
$data = json_decode($feeds,true);
foreach($data as $item=>$events) {
$date = $events=>$month.'/'.$events=>$day.'/'.$events=>$year;
$events.='<li><span class="engindate">'.$date.'</span><br /><span class="source">'.$item["title"].'</span><br />'.$item["details"].'</li>';
}
Here is the JSON sample (yes, I know it is incomplete)
{
"month": 5,
"year": 2013,
"events": [
{
"url": "http://www.engin.umich.edu/college/about/cal/events/2013/may/shavuot-ends",
"id": "shavuot-ends",
"month": 5,
"year": 2013,
"day": 16,
"startTime": "1:42",
"endTime": "1:42",
"hideTime": "true",
"deadline": "true",
"am_pm": "pm",
"am_pm_start": "pm",
"am_pm_end": "pm",
"title": "Shavuot ends",
"location": "",
"details": "Shavuot runs from May 14 to May 16.",
"host": "Michigan Engineering",
"event_type": "Holiday",
"image": {
"src": "http://www.engin.umich.edu/++resource++umich_images/default_event.jpg",
"alt": "Shavuot ends"
}
},...

Answer 1

You have mixed up your -> and => operators. Try like this:
$data = json_decode($feeds,true);
foreach($data['events'] as $event) {
$date = $event['month'].'/'.$event['day'].'/'.$event['year'];
$events.='<li><span class="engindate">'.$date.'</span><br /><span class="source">'.$event["title"].'</span><br />'.$event["details"].'</li>';
}

Answer 2

$data['events']['url']
The array is multidimensional.
foreach($data as $key=>$item) {
if($key=='events') {
$url = $item['url'];
}
}
or
foreach($data['events'] as $key=>$item) {
if($key=='url') {
$url = $item;
}
}

Answer 3

try this:
$data = json_decode($feeds);
$eventsHtml = "";
foreach($data->events as $event ) {
$date = $data->month.'/'.$event->day.'/'.$data=>year;
$eventsHtml .='<li><span class="engindate">'.$date.
'</span><br /><span class="source">'.
$event=>title.
'</span><br /><a href="'.$event=>url.'">'.
$event->details.'</a></li>';
}
You have an object "data". This has a member "month", so this is $data->month
It has a member "events" which is an array. The first event is $data->events[0]. If you iterate with a foreach, this is foreach($data->events as $event ) { having $event as the one event.
Basic errors:
$events=>$month // is inproper syntax
foreach($data as $item=>$events) {
..
$events.= // this would overwrite the iterator variable above ??
