HomeBackend DevelopmentPHP Tutorialphp curl获取不到返回值

服务器端函数
function order_kb(){
    $expressodd[0]['odd']='560860393435';
    $expressoddjson = json_encode($expressodd);
    return $expressoddjson;
}

客户端请求php文件
$post_data = array () ;
$url = 'http://www.test.com/index.php?m=user&a=order_kb' ;
$o = "" ;
foreach ($post_data as $k=>$v)
{
    $o.="$k=".urlencode($v)."&";
}
$data=substr($o,0,-1);
$ch = curl_init();
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER,0);
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
$result = curl_exec($ch);
curl_close($curl);
print_r(json_decode($result,TRUE));
print_r(json_decode($result,TRUE)[0]['odd']);//打印出来看结果
?>
为什么得不到返回值?打印出来是空白的页面

这个网站在第一次访问时会执行如下 js 代码

function setCookie(c_name, value, expiredays) {            document.cookie = c_name + "=" + escape(value) + ((expiredays==null) ? "" : ";expires=" + expiredays) + ";path=/";}function getHostUri() {            var loc = document.location;                    return loc.toString();}var exdate=new Date();exdate.setDate(exdate.getDate()+1);setCookie('DOAAuthReferrer', document.referrer, exdate.toUTCString());setCookie('DOADFgsjnrSFgsg329gaFGa3ggs9434sgSGS43tsgSHSG35', '#e25d0c3c68dea6df48ffe0664f9d86d24c31ff1d#FLBN#1467097484#1739593330#', 'Tue, 28 Jun 2016 07:04:44 GMT');try {      location.reload(true);  } catch (err1) {      try {          location.reload();      } catch (err2) {      	location.href = getHostUri();      }  }
如果你不能模拟执行的话,那么肯定是获取不到真正的数据的

实际请求$url = 'http://www.danhaoxia.com/index.php?m=user&a=order_kb' ;   麻烦看下

$url = 'http://www.danhaoxia.com/index.php?m=user&a=order_kb' ;echo file_get_contents($url);


有 BOM 头不说,根本就没有 json 的影子

刚学PHP,服务器端返回值上面做处理吗?

那个应该是我刚在服务器那边加的打印内容的测试 ,现在去掉了

去是去掉了,但是也只剩下了 BOM 头了
你是怎么调用 order_kb 函数的?

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements.
