檢索2從PHP陣列到AJAX

Question

我想從PHP檢索兩個數組使用AJAX，但我認爲json_encode只能有一個變量。你有什麼想法我可以解決這個問題嗎？我使用json_encode

<?php 
while($row = mysql_fetch_array($get_grades_boy)){ 

       $data_grades_boys[]=array(
        'fname_b'=>$row['firstname'], 
        'mname_b' => $row['middlename'], 
        'lname_b' => $row['lastname'], 
        'studnt_id_b' => $row['student_id'], 
        'grade_b' => $row['grade'], 
        ); 
      } 

      while($row2 = mysql_fetch_assoc($get_grades_girl)){ 

       $data_grades_girls[]=array(
        'fname_g'=>$row2['firstname'], 
        'mname_g' => $row2['middlename'], 
        'lname_g' => $row2['lastname'], 
        'studnt_id_g' => $row2['student_id'], 
        'grade_g' => $row2['grade'], 
        ); 
      } 
echo json_encode($data_grades_boys); 

我試着這樣做

echo json_encode($data_grades_boys); 
echo json_encode($data_grades_girls); 

檢索新手，但沒有奏效。

您需要將兩個數組合併成一個數組：

$data_grades = array(
    'boys' => $data_grades_boys, 
    'girls' => $data_grades_girls 
); 
echo json_encode($data_grades); 

和jQuery：

$ajax(
... 
success: function(data) { 
    boys = data.boys; 
    girls = data.girls 

然後

$.each(boys).function(index, value) {
