我在PHP中使用PHP中的數組到JSON結構的問題在JavaScript中使用

Question

我總是與陣列到JSON格式的鬥爭。我正在使用TexoTela的selectbox插件。該插件需要一個JSON結構爲：

{ 
    "ajax1": "AJAX option 1", 
    "ajax2": "AJAX option 2", 
    "ajax3": "AJAX option 3" 
} 

我的PHP代碼：

function get_selectfield_list($col, $table) 
    { 
     $location_list = array(); 

     //create an sql string and set it to the $sql variable 
     $sql = "SELECT id, $col FROM $table"; 

     //form the sql query and set it to the $query variable 
     $query = $this->db->query($sql); 

     //loop through the result_array and set the results to the $location_list array 
     foreach ($query->result_array() as $row) 
     { 
      $value = $row['id']; //set the database table id to to $value variable 
      $text = $row[$col]; //set the the $string value to the $text variable 
      $location_list = array($value => $text); //form the $location_list array with the the $value and $text values 
     } 

     echo json_encode($location_list); //convert the $location_list array into a json object and return it.        
    } 

我的PHP代碼返回{"4":"chickenpen 4"}

而不是{"4":"chickenpen 4","5":"chickenpen 5", etc....}

我認爲這是由於代碼：$ location_list = array（$ value => $ text）;每次foreach循環它創建一個新的數組。我如何格式化數組以輸出foreach中的所有結果而不是最後的結果？

$location_list[$value] = $text;
