php怎么发送和接收流文件

PHP 发送与接收流文件

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

1. sendStreamFile.php

<?php
/** 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)){
        $opts = array(
            &#39;http&#39; => array(
                &#39;method&#39; => &#39;POST&#39;,
                &#39;header&#39; => &#39;content-type:application/x-www-form-urlencoded&#39;,
                &#39;content&#39; => file_get_contents($file)
            )
        );
        $context = stream_context_create($opts);
        $response = file_get_contents($url, false, $context);
        $ret = json_decode($response, true);
        return $ret[&#39;success&#39;];
    }else{
        return false;
    }
}
$ret = sendStreamFile(&#39;http://localhost/fdipzone/receiveStreamFile.php&#39;, &#39;send.txt&#39;);
var_dump($ret);
?>

2. receiveStreamFile.php

<?php
/** 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[&#39;HTTP_RAW_POST_DATA&#39;])? $GLOBALS[&#39;HTTP_RAW_POST_DATA&#39;] : &#39;&#39;;
    if(empty($streamData)){
        $streamData = file_get_contents(&#39;php://input&#39;);
    }
    if($streamData!=&#39;&#39;){
        $ret = file_put_contents($receiveFile, $streamData, true);
    }else{
        $ret = false;
    }
    return $ret;
}
$receiveFile = &#39;receive.txt&#39;;
$ret = receiveStreamFile($receiveFile);
echo json_encode(array(&#39;success&#39;=>(bool)$ret));
?>
