我正在使用这段代码来显示推文,一切都很好,但我想修改脚本以从最旧到最新显示它们,而目前它们从最新到最旧显示。

我可以在代码中看到任何明显的更改或添加位置:

<?php

                // Save the contents of output buffer to the file, and flush the buffer. 
                fwrite($file, ob_get_contents()); 
                fclose($file); 
                ob_end_flush();

            }

        }

    }

}

// Display latest tweets. (Modify username to your Twitter handle)
display_latest_tweets('');
 ?>

任何帮助都会很棒:)

谢谢

当您获得最新的推文时,您可以先反转集合,然后对其进行迭代。

考虑使用类似array_reverse的东西以与您最初收到它们的顺序相反的顺序获取 $get_tweets 的内容。
