Navigating objects and arrays

Can you please show me an example in php on how to grab specific information in a loop of some kind, I want to access [language] and [answer] => [question] => everytime it is there. Thanks

You want something lke this:

<?php

foreach($foo as $i){
    echo 'Language (cue): ' . $i['cue']['language'] . "\n";
    foreach($i['responses'] as $j){
        echo 'Language (response): ' . $j['language'] . "\n";
        foreach($j['quizzes'] as $k){
            echo 'Answer: ' . $k['answer'] . "\n";
            echo 'Question: ' . $k['question'] . "\n";
        }
    }
}

?>

Two remarks:

(1) I suggested using var_export() to generate a copy and paste sample to test with it but apparently stdClass::__set_state() cannot be read back easily. Sorry if I mislead anyone.

(2) It's not difficult to build it yourself if you do it step by step.

<?php

// First
foreach($foo as $c => $v){
    var_dump($c, $v);
    exit;
}

// Second
foreach($foo as $i){
    echo 'Language (cue): ' . $i['cue']['language'] . "\n";
    foreach($i['responses'] as $c => $v){
        var_dump($c, $v);
        exit;
    }
}

// Etc.

?>
