Question

I have the following output sing var_dump.. How do I read the value of ‘transferfrom’ for each array ? The ‘ST00576’ and ‘OT01606’ are dynamic values.It can change on the subsequence arrays.

string(19) "TB3360    7D  B  70"
array(2) {
  ["ST00576"]=>
  object(stdClass)#1 (13) {
    ["transferfrom"]=>
    int(102)
    ["transferto"]=>
    int(66)
    ["BR_ID"]=>
    int(102)

  }
  ["OT01606"]=>
  object(stdClass)#2 (13) {
    ["transferfrom"]=>
    int(102)
    ["transferto"]=>
    int(66)
    ["BR_ID"]=>
    int(66)

  }
}

string(19) "TB3360    BL  A  75"
array(2) {
  ["ST00576"]=>
  object(stdClass)#3 (13) {
    ["transferfrom"]=>
    int(102)
    ["transferto"]=>
    int(66)
    ["BR_ID"]=>
    int(102)

  }
  ["OT01606"]=>
  object(stdClass)#4 (13) {
    ["transferfrom"]=>
    int(102)
    ["transferto"]=>
    int(66)
    ["BR_ID"]=>
    int(66)

  }
}

Not sure exactly what you need, but this will pick the 'transferfrom' item out of each array entry and return an array with the same keys but strings as values.

$arr = array_map(function($item) {
    return $item->transferfrom;
}, $arr);

Or:

function pick_transferfrom($item)
{
    return $item->transferfrom;
}

$arr = array_map('pick_transferfrom', $arr);

Result (shortened):

['OT01606' => 102, 'ST00576' => 102];

Or you can just iterate:

foreach ($arr as $key => $item) {
    $transferfrom = $item->transferfrom;
    // do whatever you like with $transferfrom and $key
}
