PHP just soso

用了不到一天的时间搭好了PHP环境，并且写了一个连接数据进行查询并输出JSON的例子。没接触PHP之前，觉得很难 没想到静下心来以后看了1,2个小时就能写接口了。特此Mark JUST COOL!

<?php

$con = mysql_connect("http://www.xxx.com","root","***");
if (!$con)
{
    die('Could not connect: ' . mysql_error());
}

mysql_select_db("***", $con);

$result = mysql_query("SELECT * FROM user order by createtime desc limit 20");

$arr=Array();
$index=0;
while($row = mysql_fetch_array($result))
{
    $obj=new stdClass();
    $obj->dt = $row['rid'];
    $obj->sexy = $row['sex'];
    $obj->address =$row['adress'];

    $arr[]=$obj;


}

echo json_encode($arr);
//echo $row['createtime'] . " " . $row['sex']. " " . $row['adress'];
echo "<br />";


mysql_close($con);
?>
