php多线程安装pthreads方法有一点复杂了,下面的安装步骤有一些多,希望能帮助到各位.

PHP扩展下载：https://github.com/krakjoe/pthreads

PHP手册文档：http://php.net/manual/zh/book.pthreads.php

安装脚本,代码如下:

1. #!/bin/sh
2. cd /web/soft/php
3. if [ -d "pthreads-master" ];then
4. rm -rf pthreads-master
5. fi
6. unzip pthreads-master.zip
7. cd pthreads-master
8. /web/server/php/bin/phpize
9. ./configure --with-php-config=/web/server/php/bin/php-config
10. make
11. make install
12. rm -rf pthreads-master
13. PHPINI="/web/server/php/etc/php.ini"
14. sed -i '907a extension = "pthreads.so"' $PHPINI
15. #更新php-fpm配置
16. sed -i 's%;pid = run/php-fpm.pid%pid = run/php-fpm.pid%' /web/server/php/etc/php-fpm.conf
17. sed -i 's%;error_log = log/php-fpm.log%error_log = log/php-fpm.log%' /web/server/php/etc/php-fpm.conf
18. #杀死php-fpm进程
19. ps aux | grep "php" | grep -v "grep" | awk '{print $2}' | xargs -i kill -9 {}
20. #启动php-fpm
21. /web/server/php/sbin/php-fpm

在安装过程中出现错误:

configure: WARNING: You will need re2c 0.13.4 or later if you want to regenerate PHP parsers

解决方法是安装或升级re2c 0.13.4以上版本。

下面我们用rpm包安装此库:

1. centos-5 32位：http://pkgs.repoforge.org/re2c/re2c-0.13.5-1.el5.rf.i386.rpm
2. centos-5 64位：http://pkgs.repoforge.org/re2c/re2c-0.13.5-1.el5.rf.x86_64.rpm
3. centos-6 32位：http://pkgs.repoforge.org/re2c/re2c-0.13.5-1.el6.rf.i686.rpm
4. centos-6 64位：http://pkgs.repoforge.org/re2c/re2c-0.13.5-1.el6.rf.x86_64.rpm
5. configure: error: pthreads requires ZTS, please re-compile PHP with ZTS enabled

原因:我在编译php的时候没有加入 --enable-maintainer-zts,这个必须要重新编译php,不能动态加载的.

于是我重新编译了php,在原来的编译参数基础上那个加入了 --enable-maintainer-zts ,重新编译安装php即可.

以下为一个示例,代码如下:

1. class test_thread_run extends Thread
2. {
3. public $url;
4. public $data;
5. public function __construct($url)
6. {
7. $this->url = $url;
8. }
9. public function run()
10. {
11. if(($url = $this->url))
12. {
13. <?Php
14. $this->data = model_http_curl_get($url);
15. }
16. }
17. }
18. function model_thread_result_get($urls_array)
19. {//开源代码phpfensi.com
20. foreach ($urls_array as $key => $value)
21. {
22. $thread_array[$key] = new test_thread_run($value["url"]);
23. $thread_array[$key]->start();
24. }
25. foreach ($thread_array as $thread_array_key => $thread_array_value)
26. {
27. while($thread_array[$thread_array_key]->isRunning())
28. {
29. usleep(10);
30. }
31. if($thread_array[$thread_array_key]->join())
32. {
33. $variable_data[$thread_array_key] = $thread_array[$thread_array_key]->data;
34. }
35. }
36. return $variable_data;
37. }
38. function model_http_curl_get($url,$userAgent="")
39. {
40. $userAgent = $userAgent ? $userAgent : 'Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.2)';
41. $curl = curl_init();
42. curl_setopt($curl, CURLOPT_URL, $url);
43. curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
44. curl_setopt($curl, CURLOPT_TIMEOUT, 5);
45. curl_setopt($curl, CURLOPT_USERAGENT, $userAgent);
46. $result = curl_exec($curl);
47. curl_close($curl);
48. return $result;
49. }
50. for ($i=0; $i < 100; $i++)
51. {
52. $urls_array[] = array("name" => "baidu", "url" => "http://www.111cn.net/ s?wd=".mt_rand(10000,20000));
53. }
54. $t = microtime(true);
55. $result = model_thread_result_get($urls_array);
56. $e = microtime(true);
57. echo "多线程：".($e-$t)."＼n";
58. $t = microtime(true);
59. foreach ($urls_array as $key => $value)
60. {
61. $result_new[$key] = model_http_curl_get($value["url"]);
62. }
63. $e = microtime(true);
64. echo "For循环：".($e-$t)."＼n";
65. ?>
