在PHP数组中显示多行

Question

我写了一个脚本来返回数据库中的案例记录.当实际有两条记录时,我正在为我的mysql查询返回一条记录.这是我要回来的:

{ "cases": [ {"name":"Test Case for App","number":"3846"}] } 

我应该看到:

{ "cases": [ {"name":"Test Case for App","number": "2903"}, {"name":"Test Case 2","number": "2856"} ] }

这是我的来源:

$sql = "select * from cases as c join contacts_cases as conc on c.id = conc.case_id where conc.contact_id = '1b360507'";
$query = mysql_query($sql);  

// If we find a match, create an array of data, json_encode it and echo it out  
if (mysql_num_rows($query) > 0)  
{  
    $row = mysql_fetch_assoc($query);  
    $response = array(  
        'name' => $row['name'],  
        'number' => $row['case_number']
    );  

    echo '{ "cases": [ ',  json_encode($response), "] }";

如果你期望不止一个结果,你应该尝试

if (mysql_num_rows($query) > 0)  
{  
    $responses = array();
    while($row = mysql_fetch_assoc($query)) {
        $responses[] = array(  
            'name' => $row['name'],  
            'number' => $row['case_number']
        );  
    }
    echo '{"cases": ' . json_encode($responses) . '}';
}
