for（$i=0；$i我想从下一个数组中删除其子集的数组尝试以下操作：
$existing = [];
foreach ($sugesti as $key => $sugest) {
foreach ($sugest as $key2 => $sug {
if (in_array($sug->name, $existing)) {
unset($sugesti[$key][$key2];

很难理解你想做什么。也许如果你提供上面的例子，我们可以更好地理解你在寻找什么，我想展示的是该阵列中唯一的独特项目是真正的sintaks for in_阵列？很好地挑选出来的。对不起，我得去做点什么，然后半路回来。我已经更新了示例。结果仍然是错误的，如果我使用sintaks，它会给出一个空数组，但是如果在unset函数中删除key2，它也会删除第一个元素，它是唯一的，不会在数组中重复显示，而且，该文件中仍有重复的项目array@sab896很抱歉，您需要更清楚地了解您想要什么，或者调整代码以满足您的需要。
