**I converted this code from js code which have working json part
data variable is the json out put from google, i just need convert this part to php**
for (item in data.items) {
$("#output").append(
"<hr><h3>" + data.items[item].summary + "<h3>" +
"<h4>" + data.items[item].start.date + "<h4>"
);
}

Answer 1

Your code is almost correct, you just have one foreach loop too many, once you are iterating over the items you can access their properties directly, no need to loop through them.
// Check if we got some results
if (!empty($result)) {
// Parse the results
$json = json_decode($result);
// Iterate over the item property of the resultset
foreach($json->items as $item) {
// Each item is an object,
// 'summary' and 'start' are properties of 'item'
// 'date' is a property of 'start'
echo '<hr><h3>' . $item->summary . '</h3>';
echo '<h4>' . $item->start->date . '</h4>';
}
}
I changed the name of $myData to $item, I feel that it makes the code easier to understand, feel free to update the answer if you want to preserve the name $mydata.
