I am retrieving a multidimensional php array (I think) from an API, now all of the values return perfectly and when I dump the array with print_r I get this:
Event Object
(
[title] => test
[link] => google.com
[updated] => 2013-03-06T12:08:56.521-05:00
[id] => test
[name] => Copy of Copy of Copy of Mar 05, 2013 - TEST4
[description] =>
[registered] => 2
[createdDate] => 2013-03-06T12:08:56.521-05:00
[status] => COMPLETE
[eventType] => OTHER
[eventLocation] => EventLocation Object
(
[location] => test
[addr1] => test
[addr2] =>
[addr3] =>
[city] => madrid
[state] => andalucia
[country] =>
[postalCode] => 06103
)
[registrationUrl] => https://google.com
[startDate] => 2013-03-07T13:00:00-05:00
[endDate] => 2013-03-07T13:00:00-05:00
[publishDate] => 2013-03-06T12:11:15.958-05:00
[attendedCount] => 0
[cancelledCount] => 0
[eventFeeRequired] => FALSE
[currencyType] => USD
[paymentOptions] => Array
(
)
[registrationTypes] => Array
(
[0] => RegistrationType Object
(
[name] =>
[registrationLimit] =>
[registrationClosedManually] =>
[guestLimit] =>
[ticketing] =>
[eventFees] => Array
(
)
)
)
)
Now bumbling through wit my basic PHP i have found that i can list all of the first array items from [title] to [eventType] like this:
<?php
// get details for the first event returned
$Event = $ConstantContact->getEventDetails($events['events'][0]);
reset($Event);
while (list($key, $value) = each($Event)) {
echo "$key => $value \r\n<br/>";
}
?>
my question: All I need to do it retrieve [title] and [startDate] I don't need the rest now I could just hide the rest using Js and css but i am sure i am just being an idiot and there is an easier way to traverse this array so it only spits out the two values i need. How do i do this?
You do not have to traverse the whole object. Just access the properties you want:
$title = $Event->title;
$startDate = $Event->startDate;
// or
echo $Event->title;
echo $Event->startDate;
It's actually an object - not an (associative) array!
What's the difference?
An object is an instance of a class. A class has methods and attributes (member variables).
Unlike C++ or some other OOP languages, you can define attributes dynamically without declaring them in the class declaration.
An array is simply a container for keys and their values.
