I'm trying to add an array to another array at key inside a foreach loop. Here is my function. Here is my function:

    $dirs = scandir( $dir );
    $results = array( 'folders' => [] );

    foreach ( $dirs as $dir ) {

            if ( is_dir( $this::uploads_path() . '/' . $dir ) ) {
                array_push( $results['folders'], $dir );    
            } else {

                $file = array(
                    'filename' => $dir,
                    'filesize' => 1000
                );

                $results['files'][] = $file;

            }

    }

    return $results;

It seems however I try, I get keys with empty values. Like this:

 'files' => 
    array (size=7)
      0 => 
        array (size=2)
          ...
      1 => 
        array (size=2)
          ...
      2 => 
        array (size=2)
          ...
      3 => 
        array (size=2)
          ...
      4 => 
        array (size=2)
          ...
      5 => 
        array (size=2)
          ...
      6 => 
        array (size=2)
          ...

I've also tried delaying adding the array by building a new array with the file information and adding it to $results outside the foreach loop. Thanks for the help. Would love an explanation as to why I'm getting empty values rather than just a fixed code example.

    Please show input example and expected output. – cFreed Dec 4 '16 at 0:46
  • What are you using to print array? I'm not aware of anything that'll give you "size=7" and "size=2", for example. Not var_export, print_r, nor var_dump. Whatever it is, "size =2" implies the sub-arrays are in fact there with 2 elements such as with keys filename and filesize ... but instead it prints ... for brevity. – BareNakedCoder Dec 4 '16 at 1:12
  • I was wondering about that. I'm using var_dump with Xdebug extension. – heller_benjamin Dec 4 '16 at 1:16
  • Try var_dump($results['files'][0]) to confirm what's really there. – BareNakedCoder Dec 4 '16 at 1:17
  • Wow.... Looks like its some kind of abbreviation. It's all there. I just started using Xdebug, is that a normal facet of Xdebug (that array was also nested in another array with some code). Sorry for the dumb question everyone! – heller_benjamin Dec 4 '16 at 1:19

See Xdebug documentation for var_dump

Xdebug replaces PHP's var_dump() function for displaying variables. Xdebug's version includes ... and places limits on the amount of array elements/object properties, maximum depth and string lengths.

As you said above, your are using var_dump and xdebug. It is limiting the depth of arrays its printing. So instead of seeing your real data, xdebug is truncating it to ... (after indicating size=2).

Looks like you can set xdebug.var_display_max_depth to increase the depth.

just remove the } before return.

After I remove, I've test it.

kris-roofe@krisroofe-Rev-station:~$ php test.php array(2) { ["folders"]=> array(2) { [0]=> string(1) "." [1]=> string(2) ".." } ["files"]=> array(25) { [0]=> array(2) { ["filename"]=> string(9) ".ICE-unix" ["filesize"]=> int(100) } [1]=> array(2) { ["filename"]=> string(10) ".Test-unix"

  • Thanks for the answer. That was a mistake left in from an irrelevant if statement. I removed it from the question for clarity. – heller_benjamin Dec 4 '16 at 1:06
  • it is the issue, correct it then it works. – Kris Roofe Dec 4 '16 at 1:07
  • Thanks but that was not the issue – heller_benjamin Dec 4 '16 at 1:08
  • i test it, works well when i remove it. – Kris Roofe Dec 4 '16 at 1:10
  • show more code, and var_dump dirs and you result – Kris Roofe Dec 4 '16 at 1:12
