因为这就是PHP的工作方式，除非你做一些事情来分叉这个过程。脚本在单个执行线程中执行，该线程一步一步地遍历代码。由于剩余的HTML位于循环之后，因此在循环完成之前不会呈现该HTML。

替换此：

$timestampa = $xmlData->checkerz[$x]->attributes()->labro; //stops html here
    $timestampb = $xmlData->checkerz[$x]->attributes()->day;   //or here
    $timestampc = $xmlData->checkerz[$x]->attributes()->month; //or here
    $timestampd = $xmlData->checkerz[$x]->attributes()->year;

解决了这个问题：

if ($x == 0) {
$timestampa =  $xmlData->checkerz[0]->attributes()-> labro;
$timestampb =  $xmlData->checkerz[0]->attributes()->day;
$timestampc =  $xmlData->checkerz[0]->attributes()->month;
$timestampd =  $xmlData->checkerz[0]->attributes()->year;
}
else if ($x == 1) {
$timestampa =  $xmlData->checkerz[1]->attributes()-> labro;
$timestampb =  $xmlData->checkerz[1]->attributes()->day;
$timestampc =  $xmlData->checkerz[1]->attributes()->month;
$timestampd =  $xmlData->checkerz[1]->attributes()->year;
}
else if ($x == 2) {
$timestampa =  $xmlData->checkerz[2]->attributes()-> labro;
$timestampb =  $xmlData->checkerz[2]->attributes()->day;
$timestampc =  $xmlData->checkerz[2]->attributes()->month;
$timestampd =  $xmlData->checkerz[2]->attributes()->year;
}
else if ($x == 3) {
$timestampa =  $xmlData->checkerz[3]->attributes()-> labro;
$timestampb =  $xmlData->checkerz[3]->attributes()->day;
$timestampc =  $xmlData->checkerz[3]->attributes()->month;
$timestampd =  $xmlData->checkerz[3]->attributes()->year;
}
else if ($x == 4) {
$timestampa =  $xmlData->checkerz[4]->attributes()-> labro;
$timestampb =  $xmlData->checkerz[4]->attributes()->day;
$timestampc =  $xmlData->checkerz[4]->attributes()->month;
$timestampd =  $xmlData->checkerz[4]->attributes()->year;
}

那么它在哪个迭代中失败了呢？可能您在$x中存在差异，或者可能缺少一个属性。你能用XML更新你的问题吗？同时打开dispaly_errors或检查日志，让我们知道错误消息是什么。这是一种可怕的方式。。。你应该修复你的循环。例如，jsut使用foreach并维护自己的计数器，因为我很确定这只是循环索引的问题。
