PHP SCOKET sends large files, receiving end JAVA_PHP tutorial

Client (PHP):

send.php

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

$filename = '2012_07_23.zip'; //File to be sent

fwrite($fp, $filename . "rn"); //Write the file name. Use .readLine() on the java side. The first line is the file name

$handle = fopen($filename, "r");
 
$contents = fread($handle, filesize($filename));
//fwrite($fp,$contents); //Small files can be sent like this, but large files should be divided into segments
$data_size = 1024 * 1; //1M each time
$data_count = ceil( strlen($contents) / $data_size ); //How many pieces of data are there
for( $i = 0; $i < $data_count; $i ++ )
{
$data = substr( $contents, $i * $data_size, $data_size ); //Write to transmission socket
fwrite($fp,$data); www.2cto.com
}

fclose($fp);
