want to combine multiple array in php

Question

i want to do this type

in my form i have check box array and the function i want to call as the size of check box array, now all is ok simple one time calling.

but i want to call the function as above, and store the function return value in one array

as function return array so i want to do like this

for user id 1->callfunction return array
user id 2->callfunction return array .... ....

i have try to used the array_push but i does not get any result

here is my code

$track = array();

for($i=0;$i<sizeof($usr);$i++)
        {
            if (!empty($start) and !empty($end))
            {

                $track_e = $tracker->getProjectTrack($id, $usr[$i], $taski, $start, $end);

                //$track = $tracker->getProjectTrack($id, $usr, $taski, $start, $end);
            }

            $track=array_push($track,$track_e);

        }

Please clearify the question. What does the input array look like? What does $tracker->getProjectTack() do? And what you do expect $track to look like after the for loop. — Gordon

if you want to go through array, use foreach

$track = array();
if (!empty($start) and !empty($end)){  
 foreach ($usr as $u){
  array_push($track,$tracker->getProjectTrack($id, $u, $taski, $start, $end);
 }
}

Solution:

$track=array_push($track,$track_e);

array_push doesn't return an array; it returns the new number of elements in the array, modifying the array it receives as an argument in-place. It's actually much easier to just write:

$track []= $track_e;

Suggestion:

for($i=0;$i<sizeof($usr);$i++) {
    # ...
    $track_e = $tracker->getProjectTrack($id, $usr[$i], $taski, $start, $end);

Why not simplify the process of indexing $usr and counting the number of elements in it like so:

foreach ($usr as $usr_elem) {
    # ...
    $track_e = $tracker->getProjectTrack($id, $usr_elem, $taski, $start, $end);

Array ( [0] => Array ( [0] => 5 ) [1] => Array ( [0] => 6 ) [2] => Array ( [0] => 7 ) )

instead of this it returns

Array ( [0] => Array ( [0] => Array ( [0] => 7 ) ) [1] => Array ( [0] => Array ( [0] => 9) ) )

something like that

so i want to return it in as same first one.

Please do not supply additional information to your question as an answer. SO does not work like a forum. Please use the Edit link below your question

How come you want to have an array with [0] elements that simply point to a one element array? Wouldn't the first one make a little bit more sense? Please clarify how exactly you want these arrays to be structured with some more examples and more importantly, WHY it needs to be like that.
