本文实例讲述了php发送与接收流文件的方法。分享给大家供大家参考。具体如下:

sendStreamFile.php 把文件以流的形式发送
receiveStreamFile.php 接收流文件并保存到本地

sendStreamFile.php文件:

复制代码 代码如下:
/** php 发送流文件
* @param  String  $url  接收的路径
* @param  String  $file 要发送的文件
* @return boolean
*/ 
function sendStreamFile($url, $file){ 
    if(file_exists($file)){ 
        $opts = array( 
            'http' => array( 
                'method' => 'POST', 
                'header' => 'content-type:application/x-www-form-urlencoded', 
                'content' => file_get_contents($file) 
            ) 
        ); 
        $context = stream_context_create($opts); 
        $response = file_get_contents($url, false, $context); 
        $ret = json_decode($response, true); 
        return $ret['success']; 
    }else{ 
        return false; 
    } 

$ret = sendStreamFile('http://localhost/receiveStreamFile.php','send.txt');
var_dump($ret); 
?>

receiveStreamFile.php文件:

复制代码 代码如下:
/** php 接收流文件
* @param  String  $file 接收后保存的文件名
* @return boolean
*/ 
function receiveStreamFile($receiveFile){ 
    $streamData = isset($GLOBALS['HTTP_RAW_POST_DATA'])? $GLOBALS['HTTP_RAW_POST_DATA'] : ''; 
 
    if(empty($streamData)){ 
        $streamData = file_get_contents('php://input'); 
    } 
 
    if($streamData!=''){ 
        $ret = file_put_contents($receiveFile, $streamData, true);
    }else{ 
        $ret = false; 
    } 
    return $ret; 

$receiveFile = 'receive.txt'; 
$ret = receiveStreamFile($receiveFile); 
echo json_encode(array('success'=>(bool)$ret)); 
?>

希望本文所述对大家的php程序设计有所帮助。
