Php 脱机和联机服务器处理代码的方式不同

我有一段代码在本地主机和live服务器上得到不同的处理

我不知道为什么或者该改变什么

下面是一段代码：

for($k = 0; $k < count($data['SurveyAnswer']); $k++) {
    if(isset($data['SurveyAnswer'][$k]['answer']['number'])) {
        if($data['SurveyAnswer'][$k]['answer']['number'] != '')
            $data['SurveyAnswer'][$k]['answer'] = $data['SurveyAnswer'][$k]['answer']['number'].','.$data['SurveyAnswer'][$k]['answer']['text'];
        else
            $data['SurveyAnswer'][$k]['answer'] = '';
        } else if(isset($data['SurveyAnswer'][$k]['answer']['yn'])) {
    if($data['SurveyAnswer'][$k]['answer']['yn'] == 'No')
        $data['SurveyAnswer'][$k]['answer'] = 'No,' . $data['SurveyAnswer'][$k]['answer']['text'];
    else
        $data['SurveyAnswer'][$k]['answer'] = 'Yes';
    } else if(isset($data['SurveyAnswer'][$k]['answer']['scale'])) {
        $data['SurveyAnswer'][$k]['answer'] = $data['SurveyAnswer'][$k]['answer']['scale'] . ',' . $data['SurveyAnswer'][$k]['answer']['text'];
    }
}

这就是我的localhost更改数据的方式（Windows上的PHP版本5.4.7）：

这就是我的实时服务器如何更改数据（CentOS上的PHP版本5.3.23）：

可能是版本差异导致了问题，还是有其他原因

更新

真实世界的数据，在代码之前和之后通过CakePHP调试获得：

我缩短了数据，因为大约有100个问题。

信不信由你，但这是一个版本问题。将我的PHP更新为5.4.x，它运行正常。

你确定你的数据没有在其他地方损坏吗？是的，我确定。它只有在我上传的时候才会改变。我已经上传了所有与此功能相关的控制器和模型，但它仍然可以。您的数据看起来很奇怪。例如，SurveyAnswer[1]和[2]之间至少缺少一个结束括号，或者正在进行其他操作。发布您使用的实际数据的var_导出。问题已更新。我正在将我的PHP安装更新到最新版本。希望这能解决问题
