Creating an object from an array of multiple values - php

Question

I have this function:
function getPostInfo($query, $fields, $type, $limit, $since, $until, $lang, $stopwords, $identifier) {
$url = file_get_contents('https://graph.facebook.com/search?q='.spaces($query).'&fields='.$fields.'&limit='.$limit.'&until='.$until);
$j = json_decode($url);
foreach($j->data as $v) {
if ($v->type == $type) {
$author_id = $v->from->id;
$original_id = $v->id;
$post_url = getPostUrl($original_id, $author_id);
//$description = stopWords($v->message);
$description = $v->message;
$pub_date = $v->created_time;
$post[]= array(
'author_id' => $author_id,
'orginal_id' => $original_id,
'post_url' => $post_url,
'descritpion' => $description,
'pub_date' => $pub_date
);
}
}
return (object)$post;
}
If I call for example:
$post = getPostInfo($query, $fields, $type, $limit, $since, $until, $lang, $stopwords, $identifier);
echo $post->pub_date;`
it returns empty..
I tried to strip the [] from the $post array in the function...and in this case it returns only ONE value..
Instead it should return more values, because the object should get more values from the foreach loop in the above function..
But it's not happening..
I tried also to work with normal arrays, without an object, like this:
$post = getPostInfo($query, $fields, $type, $limit, $since, $until, $lang, $stopwords, $identifier);
echo $post['pub_date'];
In this case it always returns NULL..
What I am doing wrong?
How to assign more values to the array and getting them back when I need, knowing that the things I get should contain more values. It's like an array of an array...
I am a little confused..
I like the solution with objects, but if there is any other way, then better.
This is an example of what I get from the array $post:
array(5) { [0]=> array(5) { ["author_id"]=> string(10) "1319929690" ["orginal_id"]=> string(24) "1319929690_2736172406396" ["post_url"]=> string(77) "https://www.facebook.com/permalink.php?story_fbid=2736172406396&id=1319929690" ["descritpion"]=> string(773) "It was only a matter of time. # How do they serve alcoholic drinks on Italian cruise ships? - On the rocks # What vegetables do you get with dinner on Italian cruise ships? - Leeks # What's the fastest way to get off an Italian cruise ship? - Follow the captain # When the captain of the ill fated Costa Concordia was asked if he knew where he was going he replied "off course." # So the captain of the Costa Concordia will soon be in the dock.

Answer 1

You need to call it out like this
echo $post[0]["author_id"];
echo $post[1]["author_id"];
You can also use a for each loop if you need to display all the values at once
foreach($post as $p){
echo $p["author_id"];
}

Answer 2

I'd stick to arrays personally, so return with return $post;
You would have to echo $post[0]['pub_date']; or $post[1]['pub_date']; or $post[2]['pub_date']; for the different rows.
Or you can loop
foreach ($post as $post_values){
echo $post_values['pub_date'];
}

Answer 3

Try doing somehting like this
$post[] = (object) array(
'author_id' => $author_id,
'orginal_id' => $original_id,
'post_url' => $post_url,
'description' => $description,
'pub_date' => $pub_date
);
