php - 提取具有相同ID的多行mysql php

Question

您好，我有下表:

id  request_id  ein intervention_date   time_slot
10  1   600545383   18/05/2015 00:00    AM
11  3   802877145   01/06/2015 00:00    AM
12  3   802310154   02/06/2015 00:00    PM
13  3   801777170   03/06/2015 00:00    AM

我有以下查询:

function get_coach_request_assignment_on_request_id($request_id){
        $connection = get_db();
        $query = 'SELECT * FROM coach_request_assignment WHERE request_id='.$request_id;
        return $connection->query($query);
    }

当我调用这个函数时，它只返回第一行，其中request_id=3如何提取查询返回的所有值？

这是我试过的:

$coach_request_assignment_data = get_coach_request_assignment_on_request_id($request_id);
$coach_request_assignment_data = $coach_request_assignment_data->fetch_assoc();

这就是 var_dump($coach_request_assignment_data) 的样子:

array (size=5)
  'id' => string '11' (length=2)
  'request_id' => string '3' (length=1)
  'coach_uin' => string '802877145' (length=9)
  'date_intervention' => string '2015-06-01 00:00:00' (length=19)
  'time_slot' => string 'AM' (length=2)

在此致谢...

如果这是一个 MySQLi API，那么您将需要多次调用 fetch_assoc() 以获得这些多行。您只调用了一次 ->fetch_assoc():

$results = get_coach_request_assignment_on_request_id($request_id);
$coach_data = array();
while($row = $results->fetch_assoc()) {
    $coach_data[] = $row; // push row
}
// print_r($coach_data);
