无法将类型为stdClass的对象用作数组

Question

All, I'm using a function like this:

function themeblvd_twitter_slider_default( $tweet, $options, $username ) {
    echo $tweet[0]->text;
}

The line in the function is giving me the following error: Fatal error: Cannot use object of type stdClass as array

When I do a print_r on $tweet I get the following output:

object(stdClass)#70 (19) {

How can I access the text without getting the error?

Thanks!

Answer 1

The error means exactly what it is, $tweet is not an array, thus it makes no sense trying to get its 0th index.

$tweet->text should just be fine :)

If you make sure $tweet is an array of tweet informations:

foreach($tweet as $t) {
   echo $t->text;
}

Answer 2

最简单的方法是将$tweet为数组：

$tweet = (array)$tweet;
