Reading an array

Hi all,

I am doing a var_dump on a variable and it's returning the following:

var_dump($theArrayVar);

THis returns:

object(stdClass)#2 (13) { ["id"]=> string(15) "1233434333" ["name"]=> string(21) "the name" ["first_name"]=> string(6) "the" ["last_name"]=> string(14) "name name" ["link"]=> string(54) "http://www.mysite.com/profile.php?id=1233434333" ["hometown"]=> object(stdClass)#3 (2) { ["id"]=> string(15) "1233434333" ["name"]=> string(23) "Los Angeles, California" } ["location"]=> object(stdClass)#4 (2) { ["id"]=> string(15) "1233434333" ["name"]=> string(16) "Honolulu, Hawaii" } ["bio"]=> string(12) "I like Music" ["gender"]=> string(4) "male" ["locale"]=> string(5) "en_GB" ["languages"]=> array(1) { [0]=> object(stdClass)#5 (2) { ["id"]=> string(15) "1233434333" ["name"]=> string(7) "English" } } ["verified"]=> bool(true) ["updated_time"]=> string(24) "2011-03-07T15:12:51+0000" }


I am trying to read it this way:

echo  theArrayVar[0];
echo  theArrayVar[1];
etc...

but it's not working ... anyone going any ideas of why/what I'm doing wrong please?

Thanks
PHP

Two things. First

echo  theArrayVar[0];

will never work because the variable name needs a $

echo  $theArrayVar[0];


Secondly - look at the dump and you will see that the elements have names like 'id' or 'name' and not 0, 1, 2, etc. This leaves you with two options:

1: Use foreach to read the array

foreach( $theArrayVar as $key => value )
    echo "\$theArrayVar['$key'] has value $value<br/>";


2. Use array_values to build a new array numbered from 0 upwards

   $newArray = array_values( $theArrayVar );
   echo $newArray[0];
   echo $newArray[1];


I advise you to master foreach because it is so very, very useful.

Getting nothing reuturned for some reason. Syntax? something in the foreach loop isn't working.

Some more info:

This is the line that gets the data:

$theArrayVar = json_decode(file_get_contents('https://graph.webgsite.com/me?access_token=' .$session['access_token']));

any ideas please?

thanks again
