我有这段代码尝试对每个新元素进行选择以放入数组($desArray
)中。希望不要在数组中放入与现有元素之一具有相同值的元素。
检查工作应该由in_array
函数完成,该函数检查$rss_array
. 所以array_push
只会用独特的来完成。

我要问的是in_array
事情,它不起作用并给了我这个:(
Notice: Undefined index:
后面跟着 rss_array[title],重复)然后显示结果,但重复出现。
我试图这样做:
if (in_array($item->title, $rss_array, TRUE)) {
它忽略了通知的事情,但仍然没有忽略重复项。作为记录,这些 Google、Bing 和 Free 代码分别运行得非常好。但是当我尝试通过删除重复项来统一结果时,就会发生这种“卡顿”。我该如何解决这个问题?谢谢.. :)
