php json转数组出错求助

1：先输出json

//组合医生信息JSON$jsonDoctorInfo  = "{\"mecdoctor\":[";$jsonDoctorInfo .= "{\"doctorId\":\"".$doctorId."\",\"doctorName\":\"".$strDoctorName."\", \"doctorprice\":\"".$strPrice."\",\"expertise\":\"".$strExpertise."\",\"departments\":\"".$strdepartments."\",\"doctorTitle\":\"".$strTitle."\",\"doctorPhoto\":\"".$strDoctorPhoto."\"}";$jsonDoctorInfo .= "]}";

2：获取并decode
$jsonGetDoctorInfoData = json_encode($jsonGetDoctorInfoData);
$objGetDoctorInfoData = json_decode($jsonGetDoctorInfoData);
输出：

{"mecdoctor":[{"doctorId":"","doctorName":"XXXX", "doctorprice":"122","expertise":"XXXXX","departments":"医内科","doctorTitle":"主任医师","doctorPhoto":"hmh"}]}

3：将json转换成数组

//解析JSON数据	function _json_decode($json){		$comment = false;		$out = '$x=';		for ($i=0; $i
 4：出现问题  
 Parse error: syntax error, unexpected T_DOUBLE_ARROW in /home/u945504094/public_html/config/config.inc.php(876) : eval()'d code on line 1  



回复讨论(解决方案)
 
  请帮我看看到底是错到哪了。 
 
  
$s = '{"mecdoctor":[{"doctorId":"","doctorName":"XXXX", "doctorprice":"122","expertise":"XXXXX","departments":"医内科","doctorTitle":"主任医师","doctorPhoto":"hmh"}]}';print_r(json_decode($s, true));
  
Array(    [mecdoctor] => Array        (            [0] => Array                (                    [doctorId] =>                     [doctorName] => XXXX                    [doctorprice] => 122                    [expertise] => XXXXX                    [departments] => 医内科                    [doctorTitle] => 主任医师                    [doctorPhoto] => hmh                )        ))
你并没有给出出错行附近的代码，自然也就不知道你遇到了什么问题了  
  谢谢版主，  
 我在第二步获取JSON后，将$s带入function _json_decode($json){中出现错误

  另外请问一下，为什么我通过file_get_content获取的JSON字串，decode的时候加了true参数就没法解析成数组，但是直接将获取的json付给一个变量后测试就能转成数组呢  

$urlGetDoctorInfo = "http://127.0.0.1:8080/mobileInterface/mobileDataInterface.php?Action=showDoctorInfo&doctorid=".$_REQUEST['doctorid'];$jsonGetDoctorInfoData =  file_get_contents($urlGetDoctorInfo);print_r(json_decode($jsonGetDoctorInfoData ,true));//数据就是空的//将字串穿付给变量后$s= '{"mecdoctor":[{"doctorId":"","doctorName":"XXX", "doctorprice":"122","expertise":"XXX","departments":"内科","doctorTitle":"主任医师","doctorPhoto":"hmh"}]}';print_r(json_decode($s,true));//正常输出
  
 请问这是为什么？  
  没有问题呀  
$s = '{"mecdoctor":[{"doctorId":"","doctorName":"XXXX", "doctorprice":"122","expertise":"XXXXX","departments":"医内科","doctorTitle":"主任医师","doctorPhoto":"hmh"}]}';print_r(_json_decode($s));    function _json_decode($json){        $comment = false;        $out = '$x=';        for ($i=0; $i
Array(    [mecdoctor] => Array        (            [0] => Array                (                    [doctorId] =>                     [doctorName] => XXXX                    [doctorprice] => 122                    [expertise] => XXXXX                    [departments] => 医内科                    [doctorTitle] => 主任医师                    [doctorPhoto] => hmh                )        ))
  
  是啊版主，但是用file获取的就不行。

  那是编码问题！  
 json_decode 只能识别 utf-8 编码的数据
