循环遍历 3 个数组

Question

how would I go about looping through this data here:

Array ( 
    [reply] => Array (
        [recipient] => Array ( 
            [@msisdn] => 1234123412 
            [@id] => 5b5f9635-15d7-44d8-b1e3-7015hj95c71c 
            )
    ) 
) 

So I want to get the @mssidn's and the @id's to use like this:

foreach($$$){
    $sqldata .= '(' . $last_id . ',' . $msisdn . ',' . $id . '),';
}

$last_id comes from another function, so just need the two others. I just can't seem to get it working, so any help will be much appreciated.

Answer 1

Simply iterate your array get the values by key @msisdn and @id

foreach($array as $value) {
  foreach($value as $data) {        
    $sqldata .= '(' . $last_id . ',' . $data['@msisdn'] . ',' . $data['@id'] . '),';
  }
}

Answer 2

start the foreach loop at the point in the data structure that you want to process and just loop over the contents of the inner array

foreach ($arr['reply'] as $recip){
    $sqldata .= '(' . $last_id . ',' . $recip['@msisdn'] . ',' . $recip['@id'] . '),';
}
