phph in_array找不到记录

Question

I am using in_array but it is coming back that that data I give it is not in the array although it should.

cant see what I am missing?

the array

array(3) { 
["MonthlyReturn"]=> array(11) { ["id"]=> string(3) "307" ["employee_id"]=> string(3) "553" } 
["Company"]=> array(13) { ["id"]=> string(3) "160" ["member_number"]=> string(1) "2" ["name"]=> string(5) "ger 2"  } 
["Employee"]=> array(15) { ["id"]=> string(3) "553" ["company_id"]=> string(3) "160" ["first_name"]=> string(4) "pepe" }

The php code

$employee = 554;

if (in_array($employee, (array)$existingReturns['MonthlyReturn']['employee_id'])){

Answer 1

Cause it is not an array. Why just you don't check like this,

if ($employee == $existingReturns['MonthlyReturn']['employee_id'])

Answer 2

$existingReturns['MonthlyReturn']是数组，而$existingReturns['MonthlyReturn']['employee_id']是一个字符串
