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'; else $out .= $json[$i]; }else $out .= $json[$i]; if($json[$i]== '"' && $json[($i-1)]!="\\") $comment = !$comment; } eval($out.";"); return $x; }
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

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
