Question

I am having some problem with foreach statement.Though the input to foreach statement is an array, it says

Invalid argument supplied for foreach()

and my code looks like this

foreach($res_array as $res)
     {
       foreach($res as $re)
       {
           echo $re['shortUrl'];
       }
     }

and my array looks like this

Array ( [errorCode] => 0 [errorMessage] => [results] => Array ( [http://www.telegraph.co.uk/earth/earthpicturegalleries/5966251/The-weirdest-animals-on-Planet-Earth.html?image=5] => Array ( [hash] => 2qNNV6 [shortUrl] => http://su.pr/2qNNV6 ) ) [statusCode] => OK ) 

I am getting that error for the second foreach. Please help me with this problem.

I think you want to loop over $res_array['results'], rather than $res_array. You shouldn’t need to nest your foreach loops either.

It looks like the result array contains some additional information, so you might want to do something like (untested):

$res_array = GetResultsFromSomewhere();

if ($res_array['errorCode']) {
    die("Error {$res_array['errorCode']}: {$res_array['errorMessage']}");
}

foreach ($res_array['results'] as $url => $item) {
    echo $item['shortUrl'];
}
