Reading an array
Posted on 2011-03-07
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

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_conte
any ideas please?
thanks again

$theArrayVar is NOT an array. It is an object. So if you want to read the "name" you need to use 'arrow' notation:
echo $theArrayVar->name;
The same goes for the other properties:
echo $theArrayVar->id;
The "languages" is:
echo $theArrayVar->languages[0]
It will help you "see" the right syntax if you format/indent the dump you are getting:
>>echo $theArrayVar[0];
>>echo $theArrayVar[1];
