php多线程安装pthreads步骤详解

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

复制代码

#!/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

复制代码

class test_thread_run extends Thread
{
public $url;
public $data;
public function __construct($url)
{
$this->url = $url;
}
public function run()
{
if(($url = $this->url))
{
$this->data = model_http_curl_get($url);
}
}
}
function model_thread_result_get($urls_array)
{
foreach ($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.111com.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";
?>
