1.jsonp的生成（建立一個jsonp.php）

<?php
/*
	header('Content-type: application/json');
	//獲取回撥函式名
	$callback = htmlspecialchars($_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";//連線資料庫
$db = new PDO($dsn,'root','root');//資料庫賬號密碼
$rs = $db->query("SELECT * FROM exam1");
$result_arr = $rs->fetchAll();
$arr=json_encode($result_arr);
 

<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); 		
        })
	})
 

3.

		$.getJSON("http://localhost/5_4/jsonp_use.php?jsoncallback=?&search=設計",function(obj){
			var html = '<table border="1">';
			html+='<th>編號</th><th>使用者名稱</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);
		})
 

<?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>';

<?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);
?>
