我无法使用 php 从 xml 文件中获取所有数据

问题描述：

除了所有的之外，我还可以从 xml 中获取数据.数据.下面的代码只获取最后一个的数据.我以为 foreach 会为每个人获取它，但似乎没有.

I can get the data from the xml apart from all the <Item> data. The code below only gets the data for the last one. I thought the foreach would get it for each of them but it doesn't seem to.

这是我正在使用的 php:

here's the php I'm using:

$xml = simplexml_load_file($xml_file); 
/* more code here that works OK */
foreach($xml->Report->Results->Item as $tab) {
    $tab_name = (string) $tab['itemPK'];
    $q1_result =  $tab->q1['listEntry'];
    $q2_result =  $tab->q2['listEntry'];  etc.
    $q1_comment =  escape_data($tab->q1Comments['text']);
    $q2_comment =  escape_data($tab->q2Comments['text']);
    $item_comment = escape_data($tab->item_comments['text']);
}

答

当您创建一个循环并定义一个变量时，在您的情况下，您的变量中就有了循环中的最后一个值.

When you make a loop and define a variable then you have in your case the last value from the loop in your variable.

你每次都覆盖你的变量.

You overwrite your variable everytime.

foreach($xml->Report->Results->Item as $tab) {
    $tab_name[] = (string) $tab['itemPK'];
    $q1_result[] =  $tab->q1['listEntry'];
    $q2_result[] =  $tab->q2['listEntry'];  etc.
    $q1_comment[] =  escape_data($tab->q1Comments['text']);
    $q2_comment[] =  escape_data($tab->q2Comments['text']);
    $item_comment[] = escape_data($tab->item_comments['text']);
}

尝试这样的事情.然后你就有了一个包含所有值的数组.

try something like this. Then you have an array with all the values.
