服务器 getjson.php
<?php
$con = mysql_connect("localhost","taoyong","k328b5zg");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("taoyong", $con);
$result=mysql_query("select img from imgs order by id desc");
while ($row=mysql_fetch_array($result)) {
$results[] = $row;
}
echo $jn=json_encode($results);
?>
数据库表：建一个表imgs 下面的数据可能会很快失效。
