Question

我有一个打印出新闻稿的XML文件。我希望回收新闻稿发布后的所有年份，如档案。只有唯一的价值观以下代码打印出所有年份。像“2017,2017,2017,2016,2016,2015,2015,2014”以外的“2017,2016,2015,2014,2013”。

<?php
$file = "file.xml";
$xml = simplexml_load_file($file);

foreach ($xml->Release as $release) {
   $date = $release['PublishDateUtc']; /* $date is now in format yyyy-mm-ddT06:30:00 */
   $year = substr($date, 0, 4);
   echo $year;
}

?>

记下已打印的日期。

试试这个

<?php
$file        = "file.xml";
$xml         = simplexml_load_file($file);
$yearArray   = array();
$uniqueArray = array();
foreach ($xml->Release as $release) {
    $date        = $release['PublishDateUtc'];
    /* $date is now in format yyyy-mm-ddT06:30:00 */
    $year        = substr($date, 0, 4);
    $yearArray[] = $year;
}

$uniqueArray = array_unique($yearArray);
print_r($uniqueArray);
?>

初始化了2个额外的变量并在循环中创建了几年的数组。然后打印出唯一的数组。
