Parsing SimpleXML Object data

Hi You can conver it to the array and work with is easy
libxml_use_internal_errors(TRUE);
$objXmlDocument = simplexml_load_file("https://rule34.xxx/index.php?page=dapi&s=post&q=index&tags=green_hair&limit=2");
if ($objXmlDocument === FALSE) {
echo "There were errors parsing the XML file.\n";
foreach(libxml_get_errors() as $error) {
echo $error->message;
}
exit;
}
$objJsonDocument = json_encode($objXmlDocument);
$arrOutput = json_decode($objJsonDocument, TRUE);
echo "<pre>";
print_r($arrOutput);

Parse XML to Array with SimpleXML

When loading with SimpleXML, using print_r() gives only an idea of the content and doesn't have the full content. If you want to see the full content then use ->asXML()...
$array = simplexml_load_string($xml);
echo $array->asXML();
To check the attributes of <ptu> element, (this just gives the first one)...
echo $array->ptu[0]['name'];
This uses ->ptu to get the <ptu> element and takes the first one [0] and then takes the name attribute using ['name'].

Extract data from Array/Object in PHP?

First off, I'm new to PHP and coding in general, so this might be quite an obvious answer.
I'm currently working with the Strava API, and I'm trying to extract data from an Array/Object which is the result of the following API call:
$recentactivities = $api->get('athlete/activities', array('per_page' => 100));
which returns:
Array (
[1] => stdClass Object (
[id] => XXXX
[resource_state] => 2
[external_id] => XXXX
[upload_id] => XXXX
[athlete] => stdClass Object (
[id] => XXXX
[resource_state] => 1
)
[name] => Let\'s see if I can remember how to do this cycling malarkey...
[distance] => 11858.3
[moving_time] => 1812
[elapsed_time] => 2220
[total_elevation_gain] => 44
[type] => Ride
[start_date] => 2014-07-12T13:48:17Z
[start_date_local] => 2014-07-12T14:48:17Z
[timezone] => (
GMT+00:00
) Europe/London
[start_latlng] => Array (
[0] => XXXX
[1] => XXXX
)
[end_latlng] => Array (
[0] => XXXX
[1] => -XXXX
)
[location_city] => XXXX
[location_state] => England
[location_country] => United Kingdom
[start_latitude] => XXXX
[start_longitude] => XXXXX
[achievement_count] => 4
[kudos_count] => 1
[comment_count] => 0
[athlete_count] => 1
[photo_count] => 0
[map] => stdClass Object (
[id] => a164894160
[summary_polyline] => XXXX
[resource_state] => 2
)
[trainer] =>
[commute] =>
[manual] =>
[private] =>
[flagged] =>
[gear_id] => b739244
[average_speed] => 6.544
[max_speed] => 10.8
[average_cadence] => 55.2
[average_temp] => 29
[average_watts] => 99.3
[kilojoules] => 179.9
[device_watts] =>
[average_heartrate] => 191.2
[max_heartrate] => 200
[truncated] =>
[has_kudoed] =>
)
This repeats for the most recent activities.
I'm attempting to extract average_heartrate, which I can do for a single object using the following:
$recentactivities[1]->average_heartrate;
but I'd like to extract all instances of average_heartrate from the Array. I've tried to use a foreach statement, but to be honest, I have no idea where to start.
Any help would be much appreciated.

It's actually pretty simple you can indeed use a foreach loop:
foreach($myArray as $obj){
//$obj is an object so:
if(isset($obj->average_heartrate)){
echo $obj->average_heartrate;
}
}

With this code you iterate through your array with objects and save the wanted array within an array so you can work further with it.
$heartrateArray = array(); // create a new array
//iterate through it with an foreach
foreach($recentactivities as $activity){
// save the average_heartrate as a value under a new key in the array
$heartrateArray[] = $activity->average_heartrate;
}

Array inside array, only take incoming array

I have the following array structure, this is the array passed in to $response
Array
(
[inbox] => Array
(
[0] => Array
(
[location] => 3
[ID] => 8ba84195fe79a89af1a4b5bd8c280621
[smsc_number] => +44******
[sent] => 2013-02-25 14:57:20
[coding] => Default GSM alphabet (no compression)
[remote_number] => +447****
[status] => Read
[body] => Yeppp
)
)
[outbox] => Array
(
[0] => Array
(
[location] => 2
[ID] => d22c4368fadd64e98fab64acb6b8fa34
[reference_number] => 1
[class] => 1
[coding] => Default GSM alphabet (no compression)
[remote_number] => *****
[status] => Sent
[body] => Test
)
[1] => Array
(
[location] => 0
[ID] => f0c05e8dd2578d16d73bf5dbcf2ec3e6
[class] => 1
[coding] => Default GSM alphabet (no compression)
[remote_number] => 0****
[status] => UnSent
[body] => fdgg ddfgfdg fd
)
[2] => Array
(
[location] => 1
[ID] => d7537acb1b3994ecc11369bac46c4bb6
[class] => 1
[coding] => Default GSM alphabet (no compression)
[remote_number] => 0****3
[status] => UnSent
[body] => fdgg ddfgfdg fd
)
)
)
I'm only interested in the body of the inbox array. I thought I could just do two loops to get this, or just do $response[0] but it doesn't seem to work. Heres what I have:
$response = $sms->Get();
foreach ($response[0] as $value) {
foreach ($response as $value1) {
echo($value1['body']);
}
}
I'm obviously doing something very stupid - Any help would be really appreciated

Try this
foreach ($response['inbox'] as $inb) {
echo($inb['body']); }

Stackoverflow API getting answers in array PHP

Not sure exactly which property you want to extract, but I assume it's the 'question_answers_url'.
$answersArray = Array();
for($i=0;$i<count($jsonArray['questions']);$i++){
//assuming it is the 'question_answers_url' property that you want
array_push($answersArray,$jsonArray['questions'][$i]['question_answers_url']);
}
Ought to do it.
