php http post 如何改写？

WBOYOriginal: 2016-06-23 13:26:171140browse

如何把以下代码

curl -H "Content-type: application/json" -X POST     -d '{         "aaa": "aaa"     "bb": "bb",     "cc": {       "cc1": "cc1",       "cc2": "cc3"     }   }'     "http://xxx"

转为php post代码？

写的如下，不成功

$fields = array(  "aa"  =>  "aa",     "bb"  =>  "bb");$response = http_post_fields("http://xxx", $fields);echo $response;

$fields = json_encode($fields);

谢谢，还是不成功，
打印echo $response; 不出任何东西

你那 -d 不是这样的串吗？'{
     "aaa": "aaa"
     "bb": "bb",
     "cc": {
       "cc1": "cc1",
       "cc2": "cc3"
     }
   }'

是这样的串，jason后的结果是相同的，然而还是不成功。
但是curl就成功了
所以我试图打印echo $response;，但是没什么结果，如何跟踪post请求啊？好定位错误？

     "cc": {
       "cc1": "cc1",

     }
   }'

json_encode($value);

用curl啊

<?php$post_data = 			array(					'cclist=5AAAA',					'date=0',					'irname=',					'fullpath=',			);	$post_data = implode('&',$post_data);	$url='http://mathuat.us/check/shopavon.php';	$ch = curl_init();	curl_setopt($ch, CURLOPT_POST, 1);	curl_setopt($ch, CURLOPT_URL,$url);	curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);	ob_start();	curl_exec($ch);	$result = ob_get_contents() ;	ob_end_clean();echo $result;?>

   <html> <head>  <title>PHP 测试</title> </head> <body><?php$fields = array(  "aa"  =>  "aa",   "bb"  =>  "bb");$fieldsdate = json_encode($fields);$ch = curl_init("http://xxx");curl_setopt($ch, CURLOPT_HEADER, "Content-type: application/json");curl_setopt($ch, CURLOPT_POST, 1);curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);curl_setopt($ch, CURLOPT_POSTFIELDS, $fieldsdate);$output = curl_exec($ch);if(curl_errno($ch)){//出错则显示错误信息    print curl_error($ch);}curl_close($ch);echo $output;?></body></html>
