我如何计算有多少次有词＆＃34;键＆＃34;在$ result [items_to_receive] [$ key] [name]？
答案 0 :(得分：2)
如果您的PHP版本为5.5或更高版本，则可以将array_column与preg_grep一起使用：
$totKey = count
(
preg_grep
(
'/.*Key.*/',
array_column( $result['items_to_receive'], 'name' )
)
);
否则，您必须执行所有$result['items_to_receive']项的foreach循环并检查name值。
答案 1 :(得分：1)
你可以简单地使用foreach外观遍历所有数组，然后测试名称＆＃39;使用不区分大小写的函数System.out.println(Member.count);
key的字段
