Php 如何在循环之外存储变量

我对循环外的变量有问题。我想存储下面显示的

foreach$time\u arr

循环中的

$programme\u title

变量，并返回如下字符串的简短列表：

Paid Programming The Mentalist - Black HeartsAnthony Bourdain Parts Unknown - Russia
NFL Live StosselBad Dog! - Bad to the BoneHouse - Son of Coma GuyCutlery Corner Wild
The Real Housewives of Atlanta - Secrets RevealedThe Real Housewives of Atlanta - Secrets Revealed
The Real Housewives of Atlanta - Secrets Revealed The Real Housewives of Atlanta - Secrets Revealed 
The Real Housewives of Atlanta - Secrets Revealed The Real Housewives of Atlanta - Secrets Revealed
The Real Housewives of Atlanta - Secrets RevealedThe Real Housewives of Atlanta - Secrets Revealed

当我使用此代码时：

 foreach($programme_arr as $programme)
  {
    $programme1 = $programme->item(0)->nodeValue;
    $programme_title = $programme1;
  }
  echo $programme_title;

foreach($programme_arr as $programme)
{
  $programme1 = $programme->item(0)->nodeValue;
  $programme_title = $programme1;
  echo $programme_title;
}

或者试试这个：

foreach($programme_arr as $programme)
{
  $programme1 = $programme->item(0)->nodeValue;
  $programme_title = $programme1;
}


foreach($time_arr as $time)
{
   echo $programme_title;
}

它不起作用。因此，我尝试了以下代码：

 foreach($programme_arr as $programme)
  {
    $programme1 = $programme->item(0)->nodeValue;
    $programme_title = $programme1;
  }
  echo $programme_title;

foreach($programme_arr as $programme)
{
  $programme1 = $programme->item(0)->nodeValue;
  $programme_title = $programme1;
  echo $programme_title;
}

并得到了一大串字符串：

    Step Up 3The 700 Club The Fresh Prince of Bel-Air - Not With My Cousin You Don't
The Fresh Prince of Bel-Air - Viva Lost Wages The Fresh Prince of Bel-Air - There's the Rub

等等

您能告诉我如何将

$programme\u title

变量存储在

foreach$time\u arr

中，以便打印如上所述的字符串列表吗？

这是变量范围的问题。如果要在循环复杂时访问变量，则变量必须存在于循环外部。如果您这样做：

$programme_title = NULL;
foreach($programme_arr as $programme) {
    $programme1 = $programme->item(0)->nodeValue;
    $programme_title = $programme1;
}

echo $programme_title;

您将回显

$programme\u arr

中最后一项的标题。如果要获取所有标题，需要将它们放入一个数组中：

$titles = array();
foreach($programme_arr as $programme) {
    $programme1 = $programme->item(0)->nodeValue;
    $titles[] = $programme1;
}

print_r($titles);

是的，我可以，但我尝试使用类似于

$program\u title=array（$program->item（0）->NodeValue）的东西我将获得输入，类似于
ArrayArrayArrayArrayArrayArrayArrayArrayArrayArrayArrayArrayArrayArrayArrayArrayArrayArrayArrayArrayArrayArrayArrayArrayArray
。您知道如何将变量
$programme\u title
与数组一起使用吗？您想将什么保存到
$time\u arr
？
$programme\u arr
的所有行？真的不清楚你想做什么。你对这个问题没有一点背景或更清楚的解释吗？@TomKriek是的，我想在$time\u arr循环下使用$program\u标题，因为我正在创建$xml变量，所以我可以将$program\u标题存储在$xml变量中。是的，我想得到$program\u arr的所有行，允许我在foreach$time\u arr下存储变量$program\u title。我怎么做？
