 [RESOLVED] Array Help
I'm setting up a forum for our company and I'm trying to extract some information from an array but not having any luck. If I use the below to display the array, the information I want to extract is '[icon_url]'
Can anyone help me?
PHP Code:
print_r($context['get_message']());

Re: Array Help
Use your browsers view source or send a plain text header so you can see the output of print_r formatted with whitespace.
PHP Code:
header('Content-Type: text/plain');
print_r($context['get_message']());
You can access arrays within arrays by using a format similar to this:
PHP Code:
$value = $array1['innerArray']['index'];

Re: Array Help
You should get the URL. 
Can you post the print_r output for $context?

Re: Array Help
In your first snippet you're calling $context['get_message'] as a function:
print_r($context['get_message']());
But in your second you're not calling the function:
echo $context['get_message']['icon_url'];

Pengate, if I use the below (to call the function) I get an error (forum displays a generic error message).
PHP Code:
echo $context['get_message']()['icon_url'];

Re: Array Help
Then you need to use something like this:
PHP Code:
$array = array('fart' => array('call' =>'fart'));
$ret = $array['fart']['call']();
echo($ret['food']);
function fart()
{
return array('food'=>'drink');
}

Re: Array Help
You get a parse error because you cannot use the array access notation on a non variable. You therefore need to assign the result to a temporary variable before accessing it.

Re: Array Help
Thanks visualAd...
I solved it by using the below.
PHP Code:
$array1 = $context['get_message']();
$icon_url = $array1['icon_url'];
