Php：对象比较（其中一个通过Web服务发送）

Question

I'm trying to compare two objects like this:

    if($obj1==$obj2){
    ...

But my comparison always return false!

$obj1 is a param of my function (called through a Webservice) of type "MySoapObject".

$obj2 is an object of type "MySoapObject" loaded from my database.

In my test print_r of my both objects give me this:

stdClass Object
(
    [establishment] => stdClass Object
        (
            [f_establishment_id] => 4
            [f_name] => MyEstablishment
            [f_display_name] => v
            [f_main_web_link] => 
            [f_contact] => 
            [f_country_code] => 
            [f_city] => 
            [f_zip_code] => 
            [f_postal_address] => 
            [f_default_language] => 
            [f_timezone] => 
            [f_cloud_synchronisation_action] => TO_SYNC
        )

    [site_list] => Array
        (
            [0] => stdClass Object
                (
                    [f_site_id] => Site1
                    [f_status] => TO_DISABLE
                    [f_name] => Site1
                )

        )

)

By the way, if I try this:

    if(print_r($obj1)==print_r($obj2)){
    ...

The result is true!

Have you an idea of where could be the problem? How to solve it? Thanks for your help.

Answer 1

for object comparison you can use :

 if($obj1===$obj2){
 }

check the documentation http://php.net/manual/en/language.operators.comparison.php
