PHP SCOKET发送大文件,接收端JAVA - 摘要: 本文讲的是PHP SCOKET发送大文件,接收端JAVA, 客户端(PHP): send.php [php] <?php $fp = fsockopen("127.0.0.1", 1024, $errno, $errstr, 10);   $filename = '2012_07_23.zi

客户端(PHP):

send.php

[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_count; $i ++ ) 

    $data = substr( $contents, $i * $data_size, $data_size ); //写入到传输socket 
    fwrite($fp,$data); www.th7.cn

 
fclose($fp); 
 
?> 

服务端(JAVA):
