Php 如何为数组中的每个元素调用相同的函数？

我基本上有一个表单，一旦按下submit按钮，它就会从MySQL传递数据

我从MySQL中检索了一个数组，希望为每个元素调用相同的函数。在过去的14个小时里，我尝试了一个for循环，但我无法让它为数组中的每个元素运行相同的函数

形式 我基本上需要将

pinPost（）

中的每个数组作为

$boardId

发布，然后对所有其他数组运行

pinPost（）

。让它真正容易理解这正是我想要做的

当我点击post按钮时，它将抓取第一个数组

string（18）“136234026166934321”

，将其作为

$boardId

提交到

pinPost（）

，然后它将返回到开头并运行第二个数组，

string（18）“286119451265381250”

，直到提交所有数组，基本上，它只是将相同的信息发布到不同的板上，这正是我想要做的

我尝试过执行for循环并在内部运行

pinput（）

，但我无法将板ID传递给

pinput（）

函数，因此它无法运行。

变量名可能有问题。 试着这样做：

$postBoards = $_POST['post_board_id'];

function pinLogin() 
{
    $ch         = // ch is a variable from cURL
    $cookie     = '/cookie.txt'; //cookie session
    $url        = 'http://www.website.com/';

    // Run the pinPost callback for each element of $postBoards
    // with your custom user data from this function
    array_walk("pinPost", $postBoards, array($ch, $cookie, $url);
}

function pinPost($boardId, $boardKey, $data)
{
    // You have your boardId for each submitted board available here
    $postDesc   = $_POST['post_description'];
    $postUrl    = $_POST['post_url'];
    $postImage  = $_POST['post_image'];

    // $data contains your pinPost data for example
    $ch = $data[0];
}

因此，您可以使用一些不同的技术来实现这一点。我的首选是使用，因为它的回调同时接受数组的键和值也可以在这里使用，尽管它只在回调中使用数组的值

  /**
   * logs into website with headers
   */
  function pinLogin() {
     $ch = // ch is a variable from cURL
     $cookie = '/cookie.txt'; //cookie session
     $url = 'http://www.website.com/'; // website to post data to


     /**
      * here iterate over all of your board id's and pass them to pin post function. The pinPost function
      * will be run 18 times
      */
     foreach($_POST['post_board_id'] as $boardId) {
        /**
         * @var $boardId string this is the 18 characters long stringg $boardid
         */
        pinPost($ch, $cookie, $url, $boardId);
     }
  }

  /**
   * posts the information below to the logged in website
   *
   * @param $ch
   * @param $cookie
   * @param $url
   * @param $boardId id of the board you want to pin post to (NEW PARAMETER)
   */
  function pinPost($ch, $cookie, $url, $boardId) {
     //$boardId is already here
     $postDesc = $_POST['post_description'];
     $postUrl = $_POST['post_url'];
     $postImage = $_POST['post_image'];

     /* do your stuff here */
  }

这使您的

pinPost

函数成为

$postBoards

数组中每个元素的回调函数，并将在调用

pinLogin（）

后按顺序运行每个数组条目。您可以尝试按如下方式更新代码

---

输出就在那里，正如在

$\u POST['POST\u board\u id']

上的调试所演示的那样，这并不能解决OP的问题。我选择你的答案是因为它更容易理解，更有意义，也让我有点恼火，因为我没有想到用board id运行pinLogin，但这是完美的。谢谢你的时间，如果我浪费了超过14个小时的生命，我也会很生气，但我只是学会了如何不去做，我选择了它利用你现有的思维和工作方式，而不从根本上改变你的代码。关于浪费的时间，相信我，时间不是浪费的。尝试（不管成功与否）是一种有效的学习方式。托马斯·爱迪生——我没有失败。我刚刚找到了2000种不做灯泡的方法；我只需要找到一种方法就行了。
