php - 使用php从mysql请求mp3音频文件

Question

嗨，我是 PHP 新手，我正在使用此示例代码从 mysql 读取一些简单的文本数据，然后为 IOS 应用程序请求数据。如果我想请求 mp3 音频文件怎么办？: Here's how the mp3 row looks like

<?php 

require("connect.php"); 

$db = mysqli_connect($dbServer, $dbUser, $dbPass) or die ("Could not connect to mySql"); 
mysqli_select_db($db, $dbName) or die ("Could not select database"); 

$query = "select * from mydata"; 

$result = mysqli_query($db, $query); 

while($row = mysqli_fetch_array($result)) {

    $row_set[] = $row; 
}

echo trim(json_encode($row_set));

mysqli_close($db); 

?>

尝试

<?php 

require("connect.php"); 

$db = mysqli_connect($dbServer, $dbUser, $dbPass) or die ("Could not connect to mySql"); 
mysqli_select_db($db, $dbName) or die ("Could not select database"); 

$query = "select * from mydata"; 

$result = mysqli_query($db, $query); 

while($row = mysqli_fetch_array($result)) {

    $row["str_file_mp3"] = file_get_contents($row["path_mp3"]);
    $row_set[] = $row; 
}

echo trim(json_encode($row_set));

mysqli_close($db); 

?>
