check multiple values exists php array

Question

I have an array in PHP

$permission = array( "admin", "moderator", "guest"  );

and i have another array

$userRoles = array( "admin", "moderator" );

I checked with in_array but it doesn't work with multiple values.

How can i check atleast one value in $userRoles exists on $permission without looping ?

Thanks in advance.

Use array_intersect

count(array_intersect($permission, $userRoles));

There's not need to call count() unless you really need the count. You can just use if (array_intersect($permission, $userRoles)) ....

Use array_intersect

array_intersect — Computes the intersection of arrays

array array_intersect ( array $array1 , array $array2 [, array $ ... ] )

array_intersect() returns an array containing all the values of array1 that are present in all the arguments. Note that keys are preserved.
