Question

所以我有几个亚洲和加拿大指数的选择，具有正确的价值（我从enter link description here取得

，像这样：

to setup
clear-all
setup-turtles
reset-ticks
  ask turtles [ set size 1 ]
end

to setup-turtles
create-threads 1

ask turtles [
  setxy random-xcor random-ycor
  set shape "line"
  set color 65
   ]
end

turtles-own [age]

to go
  add-age
  divide
  branch
  transform
  tick
  ask turtles [ set size 1 ]
end

breed [threads thread]
breed [cylinders cylinder]
breed [circles circle]


to add-age
  ask turtles [
    set age age + 1
  ifelse show-age?
[ set label age ]
[ set label "" ]
  ]
end

to divide
  ask turtles [
    if breed = threads or breed = cylinders [
    ifelse random 100 < 50
    [if (not any? other turtles-on patch-ahead 1) and
      (not any? other turtles-on patch-right-and-ahead 10 1) and
      (not any? other turtles-on patch-left-and-ahead 10 1)
      [hatch 1
        [let turn-degree (random(20) - 10)
          rt turn-degree
          fd 1
          set age age - 1
          ]
    ]
  ]
    [if (not any? other turtles-on patch-right-and-ahead 180 1) and
      (not any? other turtles-on patch-right-and-ahead 170 1) and
      (not any? other turtles-on patch-right-and-ahead 190 1)
      [hatch 1
        [let turn-degree (170 + random(20))
          rt turn-degree
          fd 1
          set age age - 1
        ]

        ]

      ]
    ]]
end

to branch
  ask circles [
    if random 1000 < 2[
    ifelse random 100 < 50
        [if not any? other turtles-on patch-right-and-ahead 90 1
      [hatch-threads 1
        [right 90
          fd 1
          set age 0
          set shape "line"]
    ]
  ]
    [if not any? other turtles-on patch-left-and-ahead 90 1
      [hatch-threads 1
        [left 90
          fd 1
          set age 0
          set shape "line"]
        ]
      ]
  ]]
end

to transform
  ask threads[
  if (age > 50) and (random 100 < 50)[
  set breed cylinders
  set shape "cylinder1"
  ]
  ]
  ask cylinders[
  if (age > 100) and (random 100 < 50) [
  set breed circles
  set shape "circle"
  ]
  ]
end

所以我使用这个library并使用以下方法获取数据：

<select name="symbols[]">
     <option label="Straits Times" value="^STI">Straits Times</option>
</select>

我得到一个数组，其中包含我选择的值，但它不包含有关这些值的信息：

function getYahooIndexes($params)
{

    $query = new YahooFinanceQuery;
    $symbol = $params["symbols"];
    $data = $query->indexList($symbol)->get();
    return $data;
}

我使用了他建议的方法：

 ["data"]=>
  array(5) {
    [0]=>
    object(stdClass)#234 (2) {
      ["symbol"]=>
      string(7) "^GSPTSE"
      ["components"]=>
      array(0) {
      }
    }
    [1]=>
    object(stdClass)#240 (2) {
      ["symbol"]=>
      string(8) "CADUSD=X"
      ["components"]=>
      array(0) {
      }

在源代码中，indexList方法如下所示：

indexList(array $symbol)

Query for an index which returns the symbol and name of the components. Several symbols may be passed as an array.

See http://finance.yahoo.com/intlindices?e=europe for more symbols to world indices. The caret ^ character must be part of the symbol.

$symbol = array('^GDAXI');
$data = $query->indexList($symbol)->get();

我是后端开发的初学者，所以如果我没有解释得太好，我很抱歉，我会尽力向您提供您需要的详细信息。提前感谢您的帮助！

Yahoo Finance索引使用dirkolbrich / yahoo-finance-query库
