Doing print_r() on my array I get the following:

Array ( 
    [0] => 
        stdClass Object 
        ( 
            [id] => 25 
            [time] => 2014-01-16 16:35:17 
            [fname] => 4 
            [text] => 5 
            [url] => 6 
        ) 
)

How can I access a specific value in the array? The following code does not work because of the stdClass Object

echo $array['id'];

To access an array member you use $array['KEY'];

To access an object member you use $obj->KEY;

To access an object member inside an array of objects:
$array[0] // Get the first object in the array
$array[0]->KEY // then access its key

You may also loop over an array of objects like so:

foreach ($arrayOfObjs as $key => $object) {
    echo $object->object_property;
}

Think of an array as a collection of things. Its a bag where you can store your stuff and give them a unique id (key) and access them (or take the stuff out of the bag) using that key. I want to keep things simple here but this bag can contains other bags too :)

hey i didnt understood the use of $value here ..?..and yeah am new to php ..is it a new variable that we create it for finding the key value ? –  Avinash Babu Jan 16 at 17:43
    
@CodeLover if for example we have an array $a = ['someKey' => 'someValue']; then you will get someValue returned if you access $a['someKey']. When we use the foreach loop we can access the key and value for each member of an array. –  Lucky Soni Jul 19 at 7:27
    
@LuckySoni hey i knew it .but i want to know echo $value->KEY ..what does it do ..when i tried in code ..it doesnt echoed anything –  Avinash Babu Jul 19 at 15:03
    
@CodeLover In the answer above the $value is an Object. We are accessing the key on an Object using the Object->key notation. Hope this makes sense. –  Lucky Soni Jul 19 at 18:36

Try this:

echo $array[0]->id;

You have an array. A PHP array is basically a "list of things". Your array has one thing in it. That thing is a standard class. You need to either remove the thing from your array

$object = array_shift($array);
var_dump($object->id);

Or refer to the thing by its index in the array.

var_dump( $array[0]->id );

Or, if you're not sure how many things are in the array, loop over the array

foreach($array as $key=>$value)
{
    var_dump($value->id);
    var_dump($array[$key]->id);
}
