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;
	}

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
                (
                    [doctorId] =>
