  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:
 
  #!/bin/sh
  cd /web/soft/php
  if [ -d "pthreads-master" ];then
  rm -rf pthreads-master
  fi
  unzip pthreads-master.zip
  cd pthreads-master
  /web/server/php/bin/phpize
  ./configure --with-php-config=/web/server/php/bin/php-config
  make
  make install
  rm -rf pthreads-master
  PHPINI="/web/server/php/etc/php.ini"
  sed -i '907a extension = "pthreads.so"' $PHPINI
  #更新php-fpm配置
  sed -i 's%;pid = run/php-fpm.pid%pid = run/php-fpm.pid%' /web/server/php/etc/php-fpm.conf
  sed -i 's%;error_log = log/php-fpm.log%error_log = log/php-fpm.log%' /web/server/php/etc/php-fpm.conf
  #杀死php-fpm进程
  ps aux | grep "php" | grep -v "grep" | awk '{print $2}' | xargs -i kill -9 {}
  #启动php-fpm
  /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:
 
  centos-5 32位:http://pkgs.repoforge.org/re2c/re2c-0.13.5-1.el5.rf.i386.rpm
  centos-5 64位:http://pkgs.repoforge.org/re2c/re2c-0.13.5-1.el5.rf.x86_64.rpm
  centos-6 32位:http://pkgs.repoforge.org/re2c/re2c-0.13.5-1.el6.rf.i686.rpm
  centos-6 64位:http://pkgs.repoforge.org/re2c/re2c-0.13.5-1.el6.rf.x86_64.rpm
  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:
 
  class test_thread_run extends Thread
  {
  public $url;
  public $data;
  public function __construct($url)
  {
  $this->url = $url;
  }
  public function run()
  {
  if(($url = $this->url))
  {
  <?Php
  $this->data = model_http_curl_get($url);
  }
  }
  }
  function model_thread_result_get($urls_array)
  {//开源代码phpfensi.com
  foreach ($urls_array as $key => $value)
  {
  $thread_array[$key] = new test_thread_run($value["url"]);
  $thread_array[$key]->start();
  }
  foreach ($thread_array as $thread_array_key => $thread_array_value)
  {
  while($thread_array[$thread_array_key]->isRunning())
  {
  usleep(10);
  }
  if($thread_array[$thread_array_key]->join())
  {
  $variable_data[$thread_array_key] = $thread_array[$thread_array_key]->data;
  }
  }
  return $variable_data;
  }
  function model_http_curl_get($url,$userAgent="")
  {
  $userAgent = $userAgent ? $userAgent : 'Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.2)';
  $curl = curl_init();
  curl_setopt($curl, CURLOPT_URL, $url);
  curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($curl, CURLOPT_TIMEOUT, 5);
  curl_setopt($curl, CURLOPT_USERAGENT, $userAgent);
  $result = curl_exec($curl);
  curl_close($curl);
  return $result;
  }
  for ($i=0; $i < 100; $i++)
  {
  $urls_array[] = array("name" => "baidu", "url" => "http://www.111cn.net/ s?wd=".mt_rand(10000,20000));
  }
  $t = microtime(true);
  $result = model_thread_result_get($urls_array);
  $e = microtime(true);
  echo "多线程:".($e-$t)."\n";
  $t = microtime(true);
  foreach ($urls_array as $key => $value)
  {
  $result_new[$key] = model_http_curl_get($value["url"]);
  }
  $e = microtime(true);
  echo "For循环:".($e-$t)."\n";
  ?> 。
