php array element size is limited

Question

I am getting rows from database but one column name of table is too large ie "Booking_Physical_Location_Id"

I am getting column name except last letter 'd'.

This is my code snippet:

$Con = $this->OpenMSSqlConnection($this->DBObject);

$rs = odbc_exec($Con, $q);

$Result = '';
while ($row = odbc_fetch_array($rs))
{
    $Result[] = $row;  
}
unset($rs);    
return $Result;

Here's the var_dump result of $row array

  'Booking_Id' =>
  string(15) "103090000000242"

There is no key's length limit in php, except of the script's memory limit
You have 2 different fields in your table 'Booking_Physical_Location_Id' and 'Booking_Physical_Location_I'

You can verify this using DESC TABLE_NAME
