แล้วผมเองก็เขียน PHP ด้วยมาดูกันเลยแล้วกันครับว่า เป็นไงบ้าง


<?php
class xx_xml {

// Now we can pass the contents, maybe if you want
// to use CURL, SOCK or other method.
$lines = explode(“\n”,$this->url);
foreach ($lines as $val) {
if (trim($val) == ”)
continue;
$data = $val . “\n”;

<form name=”twitterForm” action=”" method=”post” enctype=”multipart/form-data”>

media. <input type=”file” name=”media” /><br />
username. <input type=”text” name=”username” value=”" /><br />
password. <input type=”text” name=”password” value=”" /><br />
message. <input type=”text” name=”message” value=”" /><br />
<input type=”submit” value=”OK” />
</form>
อิอิ แค่ง่ายๆ นะไม่ได้ยุ่งยากอะไรมาก ก็คือ ปกติแล้วเราจะต้องส่งไปแบบหน้า post จาก form ปกติ แต่คราวนี้เรามา post แบบ cUrl ไว้ (ตรวจสอบดูก่อนนะว่า web server ได้ลง cUrl เปล่าไม่ลงใช้ไม่ได้นะ)  แล้วก็ทำการ postเหมือน form เลย

ใครจะลองเอาไปทำอะไรเล่นก็เอานะลองเข้าไปดูตัวอย่างเล่นๆ ได้ที่ http://www.meteenee.com/twitterapi/
