How can I pull only the messages from a pages Facebook wall using PHP?

I'm trying to pull the content 开发者_如何学Gofrom the following Facebook page: https://graph.facebook.com/100000123344690/feed

I'm already pulling the data successfully using the following:

        $ch = curl_init('https://graph.facebook.com/100000123344690/feed');
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
        $response = curl_exec($ch);
        $wall = json_decode($response);

        var_dump($wall->data);

Now, i'm confused on how I loop over the $wall object and output the message param. Can someone show me a simple loop outputting the message param?

This works:

foreach($wall->data as $post){
    echo $post->message;
}

what you're pulling from facebook is json formatted data. you have to convert it to an array in order to loop through it. You have to pass true to json_decode to decode it to a multidmensional array, try:

$wall = json_decode($response, true); print_r($wall);
