【问题描述】：

我正在创建一个这样的 Xml：

private function setTitle()
{
    $rC        = $this->data->rC;
    $cTimes    = array();
    $i         = 0;

    foreach ($rC as $rCKey => $rCValue)
    {
        $cTimes[] = $rCValue->input_c_start;
    }

    foreach ($rC as $rCKey => $rCValue)
    {
        $this->title = $this->titleSetTitles->addChild('title');
        $this->title->addAttribute('chapters', $cTimes[$i]);
        $i++;
    }

}

输出是这样的：

  <title chapters="00:01">
    ...
  </title>
  <title chapters="00:02">
    ...
  </title>

我现在的问题是如何在每个循环中添加章节时间，使其看起来像这样：

  <title chapters="00:01">
    ...
  </title>
  <title chapters="00:01; 00:02">
    ...
  </title>
  <title chapters="00:01; 00:02; 00:03">
    ...
  </title>

【解决方案1】：

在 foreach 循环之外有另一个变量，它会在每次迭代时附加数据。

private function setTitle()
{
    $rC        = $this->data->rC;
    $cTimes    = array();
    $i         = 0;
    $chapters  = "";

    foreach ($rC as $rCKey => $rCValue)
    {
        $cTimes[] = $rCValue->input_c_start;
    }

    foreach ($rC as $rCKey => $rCValue)
    {
        $chapters .= $cTimes[$i]."; ";
        $this->title = $this->titleSetTitles->addChild('title');
        $this->title->addAttribute('chapters', substr($chapters, 0, -2));
        $i++;
    }

}

有效，但最后我得到一个空格，你将如何制定一个条件来防止这种情况：chapters="00:00:00; 00:10:00; ">

【解决方案2】：

有一个额外的变量并像这样使用：-

private function setTitle(){
    $rC        = $this->data->rC;
    $cTimes    = array();
    $i         = 0;

    foreach ($rC as $rCKey => $rCValue){
        $cTimes[] = $rCValue->input_c_start;
    }
    $ncTime = [];
    foreach ($rC as $rCKey => $rCValue){
        $ncTime[] = $cTimes[$i];
        $this->title = $this->titleSetTitles->addChild('title');
        $this->title->addAttribute('chapters', implode(";", $ncTime));
        $i++;
     }
}
