我有这个代码试图对每个要放入数组的新元素进行选择($desArray
)。希望不要放置与数组中现有元素之一具有相同值的元素。
检查作业应由in_array
函数完成,该函数检查$rss_array
中是否已存在相同的标题。所以array_push
只会使用唯一的。{/ p>

我问的是in_array
的事情,
它不起作用,并给我这个:
Notice: Undefined index:
(后面跟着rss_array [title],反复)
然后显示结果,但副本一直显示。
我试着这样做:
if (in_array($item->title, $rss_array, TRUE)) {
它驳回了通知的事情,但仍然没有驳回重复的内容。 为了记录,这些Google,Bing和Free代码分别运作良好。但是当我尝试通过删除重复项来结合结果时,会发生这种“卡住”。 我该如何解决这个问题? 谢谢.. :))

如果您正在寻找的是确保标题是唯一的,那么您应该尝试这个
替换
if (in_array($rss_item[$item->Title], $rss_array, TRUE)) {
与
if (in_array($item->Title, array_map(function($e) { return $e['Title']; }, $rss_array))) {
这解决了2个问题:
$rss_item[$item->Title]
可能应该是$rss_item['Title']
,但这等于$item->Title
。$rss_array
搜索$item->Title
,要在$rss_array
中搜索$item->Title
中所有数组的'标题'键,这是什么array_map
确实如此。更多阅读:

您使用的是不正确的参数。
来自in_array()
文档:
If the third parameter strict is set to TRUE then the in_array() function will also check the types of the needle in the haystack.
我怀疑这是不是你想要的。
尝试以下方法:
if (in_array($item->title, $rss_array) == TRUE) {
//code
}
甚至:
if(in_array($item->title, $rss_array)){
希望这有帮助!

也许你应该像这样创建一个rss_titles帮助器数组
$rss_array = array();
$rss_titles = array();
foreach(...) {
if (in_array($item->title, $rss_titles)) {
//return false;
continue; // Maybe you dont want to return false but to continue...
} else {
// you only need to create $rss_item if the title is not in_array:
$rss_item = array(
'Title' => $item->title,
'Description' => $item->kwic,
'Url' => $item->url,
);
array_push($rss_array, $rss_item);
array_push($rss_titles, $item->title);
}
}
