如果我有[category_slug] => travel，那么我想获得all the date index that belongs to [category_slug] =＆gt; travel`
嘿，我得到正确的输出，但它没有打破它来了多次。请帮助我。
我怎样才能做到这一点？

foreach ($array as $date => $entries) {
foreach ($entries as $entry) {
if ($entry['category_slug'] == 'shopping') {
echo $date; // or return, or whatever
break 2;
}
}
}

使用简单的foreach
$keyword = 'shopping';
foreach ($arr1 as $k=>$arr)
{
foreach($arr as $k2=>$arr2)
{
if($arr2['category_slug']==$keyword)
{
echo $k;
//break; //<--- Uncommented since you need all the entries
}
}
}
答案 2 :(得分：0)
试试这个
// $ARR_INPUT is your array
$keyword_search = "shopping";
$key_to_search = "category_slug";
$flag = 0;
$output = "";
foreach($ARR_INPUT as $key1=>$arr1)
{
foreach($arr1 as $key2=>$arr2)
{
if($arr2[$key_to_search] == $keyword_search)
{
$output = $key1;
$flag = 1;
break;
}
}
if($flag==1)
{
break;
}
}
echo "Output : ".$key1;
