1.python寫法

import socket

def test_socket_timeout():
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    print "Default socket timeout: %s" %s.gettimeout()
    s.settimeout(100)
    print "Current socket timeout: %s" %s.gettimeout()
    
if __name__ == '__main__':
    #針對單個socket例項的超時
    test_socket_timeout()
 

<?php
function test_socket_timeout(){
    $socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
    $res = socket_get_option($socket, SOL_SOCKET, SO_RCVTIMEO);
    printf("Default socket timeout: %s\n", $res['sec']);

    $timeout = array('sec'=>100,'usec'=>0);
    socket_set_option($socket,SOL_SOCKET,SO_RCVTIMEO,$timeout);
    $res = socket_get_option($socket,SOL_SOCKET,SO_RCVTIMEO);
    printf("Default socket timeout: %s\n", $res['sec']);
}

test_socket_timeout();
 

socket的超時時間有傳送超時和接受超時 兩個預設是60秒 在php.ini裡面可以設定 但這裡我們主要針對單個socket例項
php 設定和獲取socket引數主要使用socket_set_option和socket_get_option兩個函式
