    )
$student=['1','2'];


$filename= array(
  array(
    "tmp_name" => "C:\xampp\tmp\phpC542.tmp",
    "error" => "0",
    "name" => "file1.pdf",
    "type" => "application/pdf",
    "size" => "410922"
  ),
  array(
    "tmp_name" => "C:\xampp\tmp\phpC562.tmp",

                [name] => file3.pdf
                [type] => application/pdf
                [size] => 846448
            )

    )

I want to create the Array in the following format.

[students] => Array
    (
        [0] => Array
            (
                [student_id] => 1
            )

        [1] => Array
            (
                [student_id] => 2
            )

    )
[files] => Array
    (
        [0] => Array
            (
                [filename] => file1.pdf              
            )
        [1] => Array
            (
                [filename] => file2.pdf              
            )
        [2] => Array
            (
                [filename] => file3.pdf
            )
    )

I am Using the following to get my array. I am successfully getting the results on student array but having problem with generating filename array and saving each file in server. My code is

$data=$this->request->getData();
$studentids=$data['student_id'];
$students=array();
foreach($studentidsas $studentids){
    $key=array('student_id');
    array_push($students,array_fill_keys($key, $studentids));
}
$files=$data['filename'];
$file=array();
foreach($files as $files){
    $key=array('filename');
    array_push($file,array_fill_keys($key, $files));
    move_uploaded_file($data['filename']['tmp_name'],WWW_ROOT.'pdffiles//'.$filename);
}

Any Help will Really Appreciated i am really stuck in this. Thanks.

Answer 1

array_push($file,array_fill_keys($key, $files['name']));

if you give the field you want to fill your array with, it will work
