Question

Suppose i have a array like this :

 Array(
      '1' => Array(
                 "ID" => 1,
                  "Name" => "name 1"
            ),
      '2' => Array (
                 Array(
                   "ID" => 2,
                   "Name" => "name 2"
                 )
             ),
      '3' => Array(
                 Array(
                   Array(
                     Array(
                        "ID" => 3,
                         "Name" => "name3"
                     )
                 )
              ),
       '4' => Array (
                 Array {
                  "ID" => 4,
                  "Name" => "name 4"
                 ),
                 Array(
                  "ID" => 5,
                  "Name" => "name 5"
                ),
                Array(
                  "ID" => 6,
                  "Name" => "name 6"
                )
             );

number of sub-arrays is not ordered it may be 3, 4 or 5 etc…
and i wanted to get :

Array(
    Array( "ID" => 1, "Name" => "name 1"),
    Array( "ID" => 2, "Name" => "name 2"),
    Array( "ID" => 3, "Name" => "name 3"),
    Array( "ID" => 4, "Name" => "name 4"),
    Array( "ID" => 5, "Name" => "name 5"),
    Array( "ID" => 6, "Name" => "name 6"));

Is there an easy way to do this ?

EDIT :

Edited the above array to add :

'4' => Array (
                 Array {
                  "ID" => 4,
                  "Name" => "name 4"
                 ),
                 Array(
                  "ID" => 5,
                  "Name" => "name 5"
                ),
                Array(
                  "ID" => 6,
                  "Name" => "name 6"
                )
             );

which aren’t nested but i still want them to be in my final array.

Thanks.

Answer 1

//Assuming your data is in $in

$out=array();
foreach($in as $k=>$v) {
  while ((is_array($v)) && (isset($v[0]))) $v=$v[0];
  //See below for next line
  $out[]=$v;
}

print_r($out);

With the marked line being either $out[$k]=$v; or $out[]=$v; depending on wether you want to keep the 1st-level keys. In your desired output you do not ,so use the shown version

Edit

With you changed input array, you need to do something like

function addtoarray($inarray, &$outarray) {
  foreach ($inarray as $i) {
    if (!is_array($i)) continue;
    if (isset($i['ID'])) $outarray[]=$i;
    else addtoarray($i,$outarray);
  }
}

$out=array();
addtoarray($in,$out);
print_r($out);

This was tested against your new input data
