家都很清楚，php是不支持多线程的。但对于需要类似多线程功能的人来说确实是个头疼的问题。好在有几种方案可以进行解决，类似多线程功能。下面是本人总结的三种实现多线程类似的方法的方案，下面是三种方案与代码实例。
1、curl_multi方法
当需要多线程的时候，可以用curl_multi一次性请求多个操作来完成，但curl走的是网络通信，效率与可靠性就比较差了的。
function main(){
$sql = "select waybill_id,order_id from waybill where status>40 order by update_time desc limit 10 ";
$data = Yii::app()->db->createCommand($sql)->queryAll(); //yii 框架格式
foreach ($data as $k => $v) {
if ($k % 2 == 0) { //偶数发一个网址
$send_data[$k]['url'] = '';
$send_data[$k]['body'] = $v['waybill_id'];
} else { //奇数发送另外一个网址
$send_data[$k]['url'] = 'http://www.abc.com';
$send_data[$k]['body']=array($v['order_id'] => array('extra' => 16));
}
}
$back_data =sendMulitRequest($send_data);
var_dump($back_data);
}
function sendMulitRequest($send_data){
$params = array();
$curl = $text = array();
$handle = curl_multi_init();
foreach ($data as $k => $v) {
if (empty($v['url'])) {
$v['url'] = "http://www.xxx.com"; //if url is empty,set defalut url
}
$reqBody = json_encode($v['body']);
$reqStream = array(
'body' => $reqBody,
);
$encRequest = base64_encode(json_encode($reqStream));
$params['data'] = $encRequest;
$curl[$k] = curl_init();
curl_setopt($curl[$k], CURLOPT_URL, $v['url']);
curl_setopt($curl[$k], CURLOPT_POST, TRUE);
curl_setopt($curl[$k], CURLOPT_HEADER, 0);
curl_setopt($curl[$k], CURLOPT_POSTFIELDS, http_build_query($params));
curl_setopt($curl[$k], CURLOPT_RETURNTRANSFER, 1);
curl_multi_add_handle($handle, $curl[$k]);
}
$active = null;
do {
$mrc = curl_multi_exec($handle, $active);
} while ($mrc == CURLM_CALL_MULTI_PERFORM);
while ($active && $mrc == CURLM_OK) {
if (curl_multi_select($handle) != -1) {
do {
$mrc = curl_multi_exec($handle, $active);
} while ($mrc == CURLM_CALL_MULTI_PERFORM);
}
}
foreach ($curl as $k => $v) {
if (curl_error($curl[$k]) == "") {
$text[$k] = (string) curl_multi_getcontent($curl[$k]);
}
curl_multi_remove_handle($handle, $curl[$k]);
curl_close($curl[$k]);
}
curl_multi_close($handle);
return $text;
}
function main(){
$sql = "select waybill_id,order_id from waybill where status>40 order by update_time desc limit 10 ";
$data = Yii::app()->db->createCommand($sql)->queryAll(); //yii 框架格式
foreach ($data as $k => $v) {
if ($k % 2 == 0) { //偶数发一个网址
$send_data[$k]['url'] = '';
$send_data[$k]['body'] = $v['waybill_id'];
} else { //奇数发送另外一个网址
$send_data[$k]['url'] = 'http://www.abc.com';
$send_data[$k]['body']=array($v['order_id'] => array('extra' => 16));
}
}
$back_data =sendMulitRequest($send_data);
var_dump($back_data);
}
function sendMulitRequest($send_data){
$params = array();
$curl = $text = array();
$handle = curl_multi_init();
foreach ($data as $k => $v) {
if (empty($v['url'])) {
$v['url'] = "http://www.xxx.com"; //if url is empty,set defalut url
}
$reqBody = json_encode($v['body']);
$reqStream = array(
'body' => $reqBody,
);
$encRequest = base64_encode(json_encode($reqStream));
$params['data'] = $encRequest;
$curl[$k] = curl_init();
curl_setopt($curl[$k], CURLOPT_URL, $v['url']);
curl_setopt($curl[$k], CURLOPT_POST, TRUE);
curl_setopt($curl[$k], CURLOPT_HEADER, 0);
curl_setopt($curl[$k], CURLOPT_POSTFIELDS, http_build_query($params));
curl_setopt($curl[$k], CURLOPT_RETURNTRANSFER, 1);
curl_multi_add_handle($handle, $curl[$k]);
}
$active = null;
do {
$mrc = curl_multi_exec($handle, $active);
} while ($mrc == CURLM_CALL_MULTI_PERFORM);
while ($active && $mrc == CURLM_OK) {
if (curl_multi_select($handle) != -1) {
do {
$mrc = curl_multi_exec($handle, $active);
} while ($mrc == CURLM_CALL_MULTI_PERFORM);
}
}
foreach ($curl as $k => $v) {
if (curl_error($curl[$k]) == "") {
$text[$k] = (string) curl_multi_getcontent($curl[$k]);
}
curl_multi_remove_handle($handle, $curl[$k]);
curl_close($curl[$k]);
}
curl_multi_close($handle);
return $text;
}
2、通过stream_socket_client 方式
function sendStream() {
$english_format_number = number_format($number, 4, '.', '');
echo $english_format_number;
exit();
$timeout = 10;
$result = array();
$sockets = array();
$convenient_read_block = 8192;
$host = "test.local.com";
$sql = "select waybill_id,order_id from xm_waybill where status>40 order by update_time desc limit 1 ";
$data = Yii::app()->db->createCommand($sql)->queryAll();
$id = 0;
foreach ($data as $k => $v) {
if ($k % 2 == 0) {
$send_data[$k]['body'] = NoticeOrder::getSendData($v['waybill_id']);
} else {
$send_data[$k]['body'] = array($v['order_id'] => array('extra' => 16));
}
$data = json_encode($send_data[$k]['body']);
$s = stream_socket_client($host . ":80", $errno, $errstr, $timeout, STREAM_CLIENT_ASYNC_CONNECT | STREAM_CLIENT_CONNECT);
if ($s) {
$sockets[$id++] = $s;
$http_message = "GET /php/test.php?data=" . $data . " HTTP/1.0\r\nHost:" . $host . "\r\n\r\n";
fwrite($s, $http_message);
} else {
echo "Stream " . $id . " failed to open correctly.";
}
}
while (count($sockets)) {
$read = $sockets;
stream_select($read, $w = null, $e = null, $timeout);
if (count($read)) {
/* stream_select generally shuffles $read, so we need to
compute from which socket(s) we're reading. */
foreach ($read as $r) {
$id = array_search($r, $sockets);
$data = fread($r, $convenient_read_block);
if (strlen($data) == 0) {
echo "Stream " . $id . " closes at " . date('h:i:s') . ".<br> ";
fclose($r);
unset($sockets[$id]);
} else {
$result[$id] = $data;
}
}
} else {
/* A time-out means that *all* streams have failed
to receive a response. */
echo "Time-out!\n";
break;
}
}
print_r($result);
}
function sendStream() {
$english_format_number = number_format($number, 4, '.', '');
echo $english_format_number;
exit();
$timeout = 10;
$result = array();
$sockets = array();
$convenient_read_block = 8192;
$host = "test.local.com";
$sql = "select waybill_id,order_id from xm_waybill where status>40 order by update_time desc limit 1 ";
$data = Yii::app()->db->createCommand($sql)->queryAll();
$id = 0;
foreach ($data as $k => $v) {
if ($k % 2 == 0) {
$send_data[$k]['body'] = NoticeOrder::getSendData($v['waybill_id']);
} else {
$send_data[$k]['body'] = array($v['order_id'] => array('extra' => 16));
}
$data = json_encode($send_data[$k]['body']);
$s = stream_socket_client($host . ":80", $errno, $errstr, $timeout, STREAM_CLIENT_ASYNC_CONNECT | STREAM_CLIENT_CONNECT);
if ($s) {
$sockets[$id++] = $s;
$http_message = "GET /php/test.php?data=" . $data . " HTTP/1.0\r\nHost:" . $host . "\r\n\r\n";
fwrite($s, $http_message);
} else {
echo "Stream " . $id . " failed to open correctly.";
}
}
while (count($sockets)) {
$read = $sockets;
stream_select($read, $w = null, $e = null, $timeout);
if (count($read)) {
/* stream_select generally shuffles $read, so we need to
compute from which socket(s) we're reading. */
foreach ($read as $r) {
$id = array_search($r, $sockets);
$data = fread($r, $convenient_read_block);
if (strlen($data) == 0) {
echo "Stream " . $id . " closes at " . date('h:i:s') . ".<br> ";
fclose($r);
unset($sockets[$id]);
} else {
$result[$id] = $data;
}
}
} else {
/* A time-out means that *all* streams have failed
to receive a response. */
echo "Time-out!\n";
break;
}
}
print_r($result);
}
3、通过多进程代替多线程
function daemon($func_name,$args,$number){
while(true){
$pid=pcntl_fork();
if($pid==-1){
echo "fork process fail";
exit();
}elseif($pid){//创建的子进程
static $num=0;
$num++;
if($num>=$number){
//当进程数量达到一定数量时候，就对子进程进行回收。
pcntl_wait($status);
$num--;
}
}else{ //为0 则代表是子进程创建的，则直接进入工作状态
if(function_exists($func_name)){
while (true) {
$ppid=posix_getpid();
var_dump($ppid);
call_user_func_array($func_name,$args);
sleep(2);
}
}else{
echo "function is not exists";
}
exit();
}
}
}
function worker($args){
//do something
}
daemon('worker',array(1),2);
function daemon($func_name,$args,$number){
while(true){
$pid=pcntl_fork();
if($pid==-1){
echo "fork process fail";
exit();
}elseif($pid){//创建的子进程
static $num=0;
$num++;
if($num>=$number){
//当进程数量达到一定数量时候，就对子进程进行回收。
pcntl_wait($status);
$num--;
}
}else{ //为0 则代表是子进程创建的，则直接进入工作状态
if(function_exists($func_name)){
while (true) {
$ppid=posix_getpid();
var_dump($ppid);
call_user_func_array($func_name,$args);
sleep(2);
}
}else{
echo "function is not exists";
}
exit();
}
}
}
function worker($args){
//do something
}
daemon('worker',array(1),2);
