Php 循环通过对象的有效方法

在我的页面中有一个部分，你可以添加、编辑或删除学校的详细信息，在用户点击enter之前，它不应该将条目保存到数据库中，所以我首先将所有数据保存在一个对象中。我的对象如下所示：

schooldetails : {
  "1": {
    "school_ctr":"schoolctr_1",
    "school":"Fiat Lux Academe",
    "course":"",
    "qualification":"High School",
    "date_grad":"06/04/2008",
    "notes":"*graduated with honors",
    "deleted":0
  },
  "2": {
    "school_ctr":"schoolctr_2",
    "school":"College of St. Benilde",
    "course":"Computer Science",
    "qualification":"Bachelor / College",
    "date_grad":"06/05/2012",
    "notes":"",
    "deleted":0
  },
  "3":{
    "school_ctr":"schoolctr_3",
    "school":"Siliman University",
    "course":"Information Technology",
    "qualification":"Post Graduate / Master",
    "date_grad":"06/06/2014",
    "notes":"",
    "deleted":0
  }
}

if (!empty($school_details_new)) {
foreach ($school_details_new as $key => $value) {

    $s_name = mysql_real_escape_string($value['school']);
    $s_degree = mysql_real_escape_string($value['course']);
    $s_type = mysql_real_escape_string($value['qualification']);
    $s_enddate = mysql_real_escape_string($value['date_grad']);
    $s_notes = mysql_real_escape_string($value['notes']);

    $sql = "INSERT INTO `SchoolDetails` (`personID`, `School`, `Type`, `End_Date`,  `Degree`, `Notes`) VALUES ($id, '$s_name', '$s_type', '$s_enddate', '$s_degree', '$s_notes');";
    $res_sql = mysql_query($sql);
}

我通过ajax传递了它，我能够通过以下代码保存信息：

if(!empty($school_details_new)){
  foreach($school_details_new as $key => $value) {
    foreach($value as $school_data => $data_values) {
      if($school_data == "school")
        $s_name = mysql_real_escape_string($data_values);
      if($school_data == "course")
        $s_degree = mysql_real_escape_string($data_values);
      if($school_data == "qualification")
        $s_type = mysql_real_escape_string($data_values);
      if($school_data == "date_grad")
        $s_enddate = mysql_real_escape_string($data_values);
      if($school_data == "notes")
        $s_notes = mysql_real_escape_string($data_values);                      
    }
  $sql = "INSERT INTO `SchoolDetails` (`personID`, `School`, `Type`, `End_Date`, `Degree`, `Notes`) VALUES ($id, '$s_name', '$s_type', '$s_enddate', '$s_degree', '$s_notes');";
  $res_sql = mysql_query ($sql);
  }
}

这实际上对我来说很好，我没有任何错误或任何东西，但我相信有一种更有效的方法可以做到这一点，而不需要很多if语句。思想？提前谢谢。

您可以这样做：

schooldetails : {
  "1": {
    "school_ctr":"schoolctr_1",
    "school":"Fiat Lux Academe",
    "course":"",
    "qualification":"High School",
    "date_grad":"06/04/2008",
    "notes":"*graduated with honors",
    "deleted":0
  },
  "2": {
    "school_ctr":"schoolctr_2",
    "school":"College of St. Benilde",
    "course":"Computer Science",
    "qualification":"Bachelor / College",
    "date_grad":"06/05/2012",
    "notes":"",
    "deleted":0
  },
  "3":{
    "school_ctr":"schoolctr_3",
    "school":"Siliman University",
    "course":"Information Technology",
    "qualification":"Post Graduate / Master",
    "date_grad":"06/06/2014",
    "notes":"",
    "deleted":0
  }
}

if (!empty($school_details_new)) {
foreach ($school_details_new as $key => $value) {

    $s_name = mysql_real_escape_string($value['school']);
    $s_degree = mysql_real_escape_string($value['course']);
    $s_type = mysql_real_escape_string($value['qualification']);
    $s_enddate = mysql_real_escape_string($value['date_grad']);
    $s_notes = mysql_real_escape_string($value['notes']);

    $sql = "INSERT INTO `SchoolDetails` (`personID`, `School`, `Type`, `End_Date`,  `Degree`, `Notes`) VALUES ($id, '$s_name', '$s_type', '$s_enddate', '$s_degree', '$s_notes');";
    $res_sql = mysql_query($sql);
}

}

这个问题可能更适合我说实话，我不认为你需要所有的if语句。您可以简单地设置变量并运行insert查询？不要使用mysql函数，因为它们已被弃用。还要在foreach循环外准备一条语句，然后在循环内使用值执行它。
