PHP array_chunk and then array_merge

Question

is there any way to merge undefined number of arrays? Array_merge doesn't work for me, cause you have to actually put those arrays as parameters, or maybe there is a way.

I've chunked an array into n - number of arrays, I do some stuff on those chunks and would like to merge some other arrays:

$chunky = array_chunk($positions);
$arraytomerge = array();
foreach($chunky as $key=>$val)
{
    do some stuff with $keys and $vals
    $arraytomerge[] = array('1','2','3','4');
}
$merged = array_merge($arraytomerge[0],$arraytomerge[1]...);

How to list arrays as array_merge parameters?

Why don't you want to insert elements into $merge array on every iteration? — user4035

Instead of doing

//do some stuff with $keys and $vals
$arraytomerge[] = array('1','2','3','4');

Just do

//do some stuff with $keys and $vals
$merged = array_merge($merged,array('1','2','3','4'));

Or better yet, just add your new items directly to the $merged array instead of creating a new array

It's ok, but as for each loop array('1','2','3','4') contains different elements

You just replace array('1','2','3','4') with whatever the array is that you have on that loop. if your stuff is in $thisarray then just use $thisarray instead of array('1','2','3','4')
