【摘要】 PHP即“超文本预处理器”,是一种通用开源脚本语言。PHP是在服务器端执行的脚本语言,与C语言类似,是常用的网站编程语言。PHP独特的语法混合了C、Java、Perl以及 PHP 自创的语法。下面是php socket如何设置超时,让我们一起来看看php socket如何设置超时的具体内容吧!
php socket如何设置超时
php socket设置超时的方法:首先如果【$waitAckSec=0】,则返回成功发送的字节;然后如果【$waitAckSec】大于0,则返回发送后接收到得内容;最后任何情况下,失败都返回FALSE。

php socket设置超时的方法:
php创建socket的方法和设置超时的方法,贴出来分享一下
//如果$waitAckSec=0,则返回成功发送的字节 //如果$waitAckSec大于0,则返回发送后接收到得内容 //任何情况下,失败都返回FALSE function sendUdp($host, $port, $buff,$waitAckSec=0) { $socket = ($result = @socket_create(AF_INET,SOCK_DGRAM,SOL_UDP)); //发送超时1秒 socket_set_option($socket,SOL_SOCKET,SO_RCVTIMEO,array("sec"=>3, "usec"=>0 ) ); //接收超时6秒 socket_set_option($socket,SOL_SOCKET,SO_SNDTIMEO,array("sec"=>6, "usec"=>0 ) ); if($socket){ $result = @socket_sendto($socket,$buff,strlen($buff),0,$host,$port); if($waitAckSec>0){ $result = FALSE; $read = array($socket); $write = NULL; $except = NULL; if(@socket_select($read,$write,$except,$waitAckSec)>0){ $fromHost = ""; $fromPort = 0; @socket_recvfrom($socket,$result,4096,0,$fromHost,$fromPort); $result = phpext_unpack($result); if($result["needAck"] == 1){ $this->sendUdp($host, $port, $result["ackdata"]); if(isset ($result['data']['list']) && isset ($result['data']['totalCount'])){ $list = $result['data']['list']; $count = $result['data']['totalCount']; while($count> count($list)){ @socket_recvfrom($socket,$result_temp,4096,0,$fromHost,$fromPort); $result_temp = phpext_unpack($result_temp); $this->sendUdp($host, $port, $result_temp["ackdata"]); $list = array_merge($list,$result_temp['data']['list']); } $result['data']['list'] = $list; } }else{ @socket_recvfrom($socket,$result,4096,0,$fromHost,$fromPort); $result = phpext_unpack($result); if($result["needAck"] == 1){ $this->sendUdp($host, $port, $result["ackdata"]); if(isset ($result['data']['result']) && isset ($result['data']['userID'])){ $list = $result['data']['list']; $count = $result['data']['totalCount']; while($count> count($list)){ @socket_recvfrom($socket,$result_temp,4096,0,$fromHost,$fromPort); $result_temp = phpext_unpack($result_temp); $this->sendUdp($host, $port, $result_temp["ackdata"]); $list = array_merge($list,$result_temp['data']['list']); } $result['data']['list'] = $list; } } } }else{ $result = SEND_UDP_ERROR; } } @socket_close($socket); } return $result; }
