This is an article on How to Fix Cannot use object of type stdClass as array in Content Management System.
Working in Wordpress I wanted to check the type of page. I.e. is the content type as page or post. I used the global $post Wordpress variable and when I did variable dump for the object using print_r.
Code:
echo '<pre>';print_r($post);echo'</pre>';
I got
Code:
    [post_title] => Hello world!
    [post_excerpt] => Small Description about the post.
    [post_status] => publish
    [comment_status] => open
    [ping_status] => open
    [post_password] => 
    [post_name] => hello-world
    [to_ping] => 
    [pinged] => 
    [post_modified] => 2011-03-12 13:57:23
    [post_modified_gmt] => 2011-03-12 13:57:23
    [post_content_filtered] => 
    [post_parent] => 0
    [guid] => Post URI
    [menu_order] => 0
    [post_type] => post
    [post_mime_type] => 
    [comment_count] => 0
    [ancestors] => Array
        (
        )
 
    [filter] => raw
So when I tried using as $post['post_type'] I got the following error.

Fatal error: Cannot use object of type stdClass as array

Searching online I found lot of solutions that talk about Upgrading PHP as well as doing ini settings change. I was sure that I am not going to do anything of that sort and finally I found that $post is an object and not an array and so you should access it like

PHP Code:
$post->post_type 
and not

PHP Code:
$post['post_type'] 
I hope this helps lot of fellow Wordpress Developer's

when i echo it, it didn't show anything,
echo $response;then i thought, maybe its an array so i put this code:
echo "<pre>";
var_dump($response);
echo "</pre>";it worked, i got these results on my browser: OUTPUT:
object(stdClass)#6 (9) {
["Timestamp"]=>
string(20) "2007-07-18T04:50:52Z"
["Ack"]=>
string(7) "Success"
["CorrelationID"]=>
string(13) "28c01821ba2c2"
["Version"]=>
string(8) "2.400000"
["Build"]=>
string(6) "1.0006"
["Amount"]=>
object(stdClass)#7 (2) {
["_"]=>
string(5) "40.00"
["currencyID"]=>
string(3) "USD"
}
["AVSCode"]=>
string(1) "X"
["CVV2Code"]=>
string(1) "M"
["TransactionID"]=>
string(17) "14E028078XJ827961UX"
}
ok, i didn't want to show this to my users, instead, i wanted to show only the TransactionID part so i put this code instead:
echo $response['TransactionID'][17];
that's when i got this error:
Fatal error: Cannot use object of type stdClass as array in C:windows-htdocs-cart.php on line 535
ok, so how do you fix this error,i looked it up on google and found some post and forums where it say to upgrade my php or change the softwar or that i have a bad script. well, i finally figured out. it turns out that $response is actually an object. i have no idea what are objects in PHP but i came across an article about ojects and i found out that if you want to display it or show it with echo or print, you actually have to use the a different format. so in my example above, if i wanted to show the value TransactionID, this is how i would do it:

CODE
echo $response->TransactionID;
OUTPUT:
14E028078XJ827961UX
