1.jsonp的生成（建立一个jsonp.php）

<?php/*header('Content-type: application/json');//获取回调函数名$callback = htmlspecialchars($_REQUEST ['callback']);$arr=array('name'=>'haoyunyun','sex'=>'man');//print_r($arr);$arr=json_encode($arr);$callback=isset($_GET['callback'])?$_GET['callback']:"data";    echo $callback."(".$arr.")";*//*$dsn = "mysql:host=127.0.0.1;dbname=php7";//连接数据库$db = new PDO($dsn,'root','root');//数据库账号密码$rs = $db->query("SELECT * FROM exam1");$result_arr = $rs->fetchAll();$arr=json_encode($result_arr);

1.1jsonp在不同域名下调用，建立个html页面引入jquery

<script src="jq.js"></script><script>$(function(){  $.getJSON("http://localhost/7study/bookes/3.php?callback=?",function(e){            //alert(e);            console.log(e);        })})</script>

$(function(){  $.getJSON("http://localhost/7study/20160504/index.php/welcome/aaa?callback=?",function(obj){            time="<ul><li>"+obj.name+"</li><li>"+obj.sex+"</li></ul>";        $("#list").html(time);         })})

$.getJSON("http://localhost/5_4/jsonp_use.php?jsoncallback=?&search=设计",function(obj){var html = '<table border="1">';html+='<th>编号</th><th>用户名</th>';for(var i = 0;i<obj.length;i++){html+='<tr>';html+='<td>'+obj[0]['id']+'</td>';html+='<td>'+obj[i]['content']+'</td>';html+='<tr>';}html+='</table>';$("#list").html(html);//concole.log(obj);})

2.xml格式的生成建立一个php页面

<?php$arr=array('name'=>'miweitian','sex'=>'man');$a=json_encode($arr); $aa=json_decode($a,true);header("content-type:application/xml");    echo '<?xml version="1.0" encoding="utf-8" ?>';        echo "<note>";     foreach($aa as $key => $val){     echo "<as>";     echo $val;     echo "</as>";     }echo '</note>';

2.调用xml格式

<?php$url="http://localhost/7study/bookes/3.php";$html=simplexml_load_file($url);$a=json_encode($html);$b=json_decode($a,true);print_r($b);?>
