Getting Undefined offset: 0 php array

Question

I have the following array result returning from a table when called from xmlrpc client and want to send the this response to client side.

array(17) {
      ["A"]=>
      int(1)
      ["B"]=>
      int(0)
      ["pnl"]=>
      int(1)
      ["C"]=>
      int(1)
      
      ["buttons"]=>
      array(5) {
        [1]=>
        string(9) "ABC"
        [2]=>
        string(5) "DEF"
        [3]=>
        string(5) "G"
        [4]=>
        string(7) "H"
        [5]=>
        string(9) "I"
      }
      ["List"]=>
      string(580) "<th title="S">Ticker</th><th title="Position - Shares Held in Portfolio">Pos</th><th title="Average Cost">Cost</th><th title="Current Market Price">Price</th>"
    }

Currently using the following code to fetch the record but it returns undefined offsets .i got the above result using the var_dump function which contains all the data fetched . how can i change my loop to get the result in appropriate row?

var_dump($model) ;

        for ($i = 0; $i < count($model); ++$i) {
            $xml_rpc_rows[$i] = array($model[$i], 'struct');
        }
       
    }
   $response = array(
        $xml_rpc_rows,
        'struct');
    return $this->xmlrpc->send_response($response);

please also note before entering foreach() check if desired $variable is fit for foreach or you'll get errors (in views mostly). — Kyslik

Your loop wants the following index from the array: $xml_rpc_rows[$i] which would translate to $xml_rpc_rows[0], so index == 0. But your array has only indexes (keys) as: $xml_rpc_rows['A'].

The loop would also not work on the buttons array, since the first index for that array is 1. So your loop would need $i=1.

A foreach loop would give you more info and make it a bit clearer.

<?php
foreach ($model as $key => $val) {
  print $key . '<br />';
  print $val;
}

Now you can see the key / index your array uses and the values those contain.

While creating your array you used letters as indexes but in your loop you're trying to use numerical indexes. Instead of that you should use foreach to iterate through this array.

$i=0; foreach ($model as $row): $xml_rpc_rows[$i]=$row; $i++; endforeach;

No, there is no index $i in $row.

Mubarak Over a year ago

yeah that line did cause offset issue again .. here is the response without ($row[$i] ,'struct')
