How to iterate over an array of stdObject elements in PHP? - php

Question

This is the print_r() version of a data structure that I need to access via a foreach loop:
stdClass Object
(
[DetailedResponse] => Array
(
[0] => stdClass Object
( ...
)
[1] => stdClass Object
(
...
Now, how do I iterate though these objects?
I can sense that I should be doing something like this:
$object->DetailedResponse[0];
$object->DetailedResponse[1];
But how do I put it in a foreach type loop!!

Answer 1

seems like there are multiple objects in that obj.. you might need to do more foreach loops..
this code should get you the first sessionId in that obj.
foreach ($detailedresponses as $detailedresponse) {
foreach ($detailedresponseas as $response) {
echo $response->sessionId;
}
}
run this code to see the obj in a clearer way:
echo '<pre>'; print_r($detailsresponses); exit;
replace '$detailedresponses' with your correct variable name and post it back here, it should make things easier to read.
EDIT
check out this URL, I put my test data in there:

I recreated the object you're getting and put comments in there so you can understand what's happening :)
AND, you can get the properties like this:
echo $object->DetailedResponse[0]->sessionId;

Answer 2

very simple. you have a so called standard-object of php.
it's accessable like any other object in php by the $object->property syntax
so you can iterate over it this way:
foreach($object as $property), or foreach($object as $prop_name => $prop_val)
where you can access the properties by $object->$prop_name.

Answer 3

If you want to save a class, for re-using it later, you'd better to use serialize and unserialize()

Got a good solution to this - had a stdClass that contained other stdClases and arrays
function cleanEveryElement($someStdClass) {
foreach ($someStdClass as &$property) {
if ($property instanceof stdClass || is_array($property)) {
$property = cleanEveryElement($property);
}
else {
// Perform some function on each element, eg:
$property = trim($property);
}
}
return $someStdClass;
}
