The result should be for studentid array is
[studentid] => 36399,96500,96503,96509,96512 and so on..

[started] => 1

[1] => Array
(
[0] => 36399

[3] => Array

[0] => 96501

[2] => 96507
[3] => 96510
[4] => 96513

[3] => 96511
[4] => 96514
)
)
[name] => Test
[name_or_email] =>
[submitbtn] => 1
)

assuming your variable is $studentsResult (which contains the whole array you have posted)
in that case:
foreach($studentsResult['studentid'] as $studentId => $studentValues){
$tempStudents[$studentId] = join(',',$studentValues);
}
and then $tempStudents is what you're probably looking for\
If, however all those IDs needs to be under that ONE student, then you haven't said where is the ID, but you can follow the answer on flattening the array in one of the comments or do:
$tempStudents = [];
foreach($studentsResult['studentid'] as $someId => $studentValues){
$tempStudents = array_merge($tempStudents,$studentValues);
}
echo join(',',$tempStudents);

How to extract and access data from JSON with PHP?

I'm trying to find a value in a nested JSON using PHP. I've done a print_r() of it and get:
Array
(
[types] => Array
(
[0] => Array
(
[name] => Running
[arabicName] => الجاري
[categories] => Array
(
[0] => Array
(
[name] => Entertainment
[arabicName] => تسلية
[programs] => Array
(
[0] => Array
(
[id] => 375
[name] => Saalo Marteh
[arabicName] =>

[1] => Array

[id] => 491
[name] => Celebrity Duets
[arabicName] =>
[image] => http://plus.mtv.com.lb/Chrome/KPanel/Pictures/Programs/151108084429774.jpg
)
I'm trying to get the value for name and id under the entertainment header.
I've tried the following but no luck:
echo $json['types']['categories'][0]['name'];

foreach ($json['types'][0]['categories'][0]['programs'] as $value) {
echo $value['id'] . ' ' . $value['name'];
}

$this->load->library('opencloud');
$opencloud = new Opencloud;
$containers = $this->opencloud->list_containers();
print_r($containers);
The above code outputs the following array:
Array ( [0] => Array ( [name] => .CDN_ACCESS_LOGS [count] => 2 [bytes]
=> 606 ) [1] => Array ( [name] => Michael Grigsby [count] => 9 [bytes] => 891976 ) [2] => Array ( [name] => Random Photos [count] => 0 [bytes] => 0 ) [3] => Array ( [name] => hello [count] => 10 [bytes] =>
1129257 ) [4] => Array ( [name] => hello_world [count] => 1 [bytes] =>
659737 ) [5] => Array ( [name] => hi [count] => 0 [bytes] => 0 ) )
When I echo out $containers[1]['name'] I get: Michael Grigsby. My question is how do I get the script to output all of the name values rather than simply one?

You can echo the name of each array in this classic mode in PHP with a foreach loop like this:
foreach($containers as $container){
echo($container['name']);
}

<?php
foreach($mainarray as $onearray){
echo $onearray['name'];
}
?>

You can loop around the array with for loop in the following way:
for ($i = 0; $i < count($containers); $i++) {
echo $containers[$i]['name'];
}
Alternatively, you can use a foreach loop to directly get the content without any manipulation of array indexes.

I have an array and need to be sorted (based on id):
Array
(
[0] => Array
(
[qty] => 1
[id] => 3
[name] => Name1
[sku] => Model 1
[options] =>
[price] => 100.00

[1] => Array
(
[qty] => 2
[id] => 1
[name] => Name2
[sku] => Model 1
[options] => Color: <em>Black (+10$)</em>. Memory: <em>32GB (+99$)</em>.
[price] => 209.00
)
)
Is it possible to sort my array to get output (id based)?

[0] => Array

[qty] => 2
[id] => 1
[name] => Name2

Thanks!

Try like
$id_arr = array();
foreach ($my_arr as $key => $value)
{
$id_arr[$key] = $value['id'];
}
array_multisort($id_arr, SORT_DESC, $my_arr);
You can also place SORT_ASC for assending order.Better you add ORDER BY id to the query through which you are getting this array of results

function cmp($a, $b) {
return $a["id"] - $b["id"];
}
usort($arr, "cmp");//$arr is the array to sort

I want to sort it by "data".
I want to display the "data" and for each data the elements...

Try the ksort function or the array-multisort
Check the php documentation: http://php.net/manual/en/function.ksort.php
