check multiple values exists php array
提问by Red
I have an array in PHP
我在 PHP 中有一个数组
$permission = array( "admin", "moderator", "guest" );
and i have another array
我还有另一个数组
$userRoles = array( "admin", "moderator" );
I checked with in_arraybut it doesn't work with multiple values.
我检查过，in_array但它不适用于多个值。
How can i check atleast one value in $userRolesexists on $permissionwithout looping ?
如何$userRoles在$permission不循环的情况下检查存在的至少一个值？
Thanks in advance.
提前致谢。

array_intersect— 计算数组的交集

array_intersect ( array $array1 , array $array2 [, array $ ... ] )array_intersect()返回一个数组，其中包含所有参数中出现的 array1 的所有值。请注意，密钥被保留。
