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

if (!$comment){

if ( ($json[$i] == '{') || ($json[$i] == '[') )

$out .= ' array(';

else if (($json[$i] == '}') || ($json[$i] == ']'))

$out .= ')';

else if ($json[$i] == ':')

$out .= '=>';

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

------解决方案--------------------

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

if (!$comment){

if ( ($json[$i] == '{')

------解决方案--------------------

($json[$i] == '[') )

$out .= ' array(';

else if (($json[$i] == '}')

------解决方案--------------------

($json[$i] == ']'))

$out .= ')';

else if ($json[$i] == ':')

$out .= '=>';

else

$out .= $json[$i];

}else

$out .= $json[$i];

if($json[$i]== '"' && $json[($i-1)]!="\\")

$comment = !$comment;

}

eval($out.";");

return $x;

}Array

[mecdoctor] => Array

[0] => Array
