php array search function

Question

My array pattern is

$arrayError= Array ( 
                        [user_name] => 1 
                        [user_pass] => 1 
                        [email] => 1 
                        [iagree] => 1 
                    )   

I have to check if email is exist and it's value is 1 in the array

Does anyone know how to do this?
