客户端(PHP):

send.php

[php]
$fp = fsockopen("127.0.0.1", 1024, $errno, $errstr, 10);

$filename = '2012_07_23.zip'; //要发送的文件

fwrite($fp, $filename . "\r\n"); //写入文件名 java端用.readLine()..第一行就是文件名

$handle = fopen($filename, "r");

$contents = fread($handle, filesize($filename));
//fwrite($fp,$contents); //小文件可以这样发，但大文件请分段
$data_size = 1024 * 1; //每次1M
$data_count = ceil( strlen($contents) / $data_size ); //有多少块数据
for( $i = 0; $i {
    $data = substr( $contents, $i * $data_size, $data_size ); //写入到传输socket
    fwrite($fp,$data); www.2cto.com
}

fclose($fp);
