php的多線程使用

PHP 5.3 以上版本,使用pthreads PHP擴展,可使PHP真正地支持多線程。多線程在處理重複性的循環任務,可以大大縮短程序執行時間。php

在liunx下的安裝git

準備工做:github

1.下載Threading for PHP安裝包https://github.com/krakjoe/pthreadswindows

2.php安裝包安全

php安裝時必定要加上--enable-maintainer-zts參數    這個是安全線程服務器

yum install php-devel php-pear httpd-devel 
wget http://www.php.net/distributions/php-5.5.8.tar.gz 
tar zxvf php-5.5.8.tar.gz
cd php-5.5.8.tar.gz
./configure --prefix=/usr/local/php --with-config-file-path=/etc --enable-maintainer-zts
make && make install
( make -j3 && make -j3 install) -> Faster building
cp php.ini-development /etc/php.ini
pecl install pthreads
提示錯誤
error: pthreads requires ZTS, please re-compile PHP with ZTS enabled
不對啊 我加了安全線程參數了 怎麼還報錯。。。
好像剛纔用yum安裝php-devel的時候安裝了php
因而
yum remove php
從新編譯在安裝
pecl install pthreads
提示錯誤 ERROR: `phpize' failed
cd /usr/local/php/bin/
查看是否有phpize
發現有phpize,說明不是php-devel的問題
是安裝擴展的方式出了問題,因此php安裝是沒有問題的
下載pthreads擴展包
unzip pthreads-master.zip
cd pthreads
/usr/local/php/bin/phpize
./configure --with-php-config=/usr/local/php/bin/php-config
make && make install
提示Installing shared extensions:     /usr/local/php/lib/php/extensions/no-debug-zts-20121212/
說明安裝成功
修改php.ini文件,添加extension=pthreads.so
echo "extension=pthreads.so" >> /etc/php.ini
php -v
提示Warning: PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/pthreads.so' - /usr/lib64/php/modules/pthreads.so: cannot open shared object file: No such file or directory in Unknown on line 0
尼瑪都沒一件順心的安裝
錯誤 我擦
查看一下 /usr/local/php/include/php/main/php_config.php 裏面是否有#define ZTS 1
裏面有這個啊 我擦 這是什麼問題呢 繼續百度

從新安裝一次試試看

cd php-5.5.8.tar.gz

./configure --prefix=/usr/local/php --with-config-file-path=/etc --enable-maintainer-zts
make -j3 && make -j3 install
cp php.ini-development /etc/php.ini

進入pthreads解壓目錄
cd ~/soft/pthreads-master
運行phpize腳本
/usr/local/php/bin/phpize
./configure --with-php-config=/usr/local/php/bin/php-config

make && make install
提示安裝成功
echo "extension=pthreads.so" >> /etc/php.ini
php -v

PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/pthreads.so' - /usr/lib64/php/modules/pthreads.so: undefined symbol: core_globals_id in Unknown on line 0多線程

尼瑪仍是一樣的錯誤   不知道了curl

 windows下多線程的使用測試

本人php版本是5.4.17的因此下載php_pthreads-0.1.0-5.4-ts-vc9-x86.zip文件包,其中0.1.0表示爲當前pthreads版本號,5.4爲php版本號,ts就是以前判斷php對應的ts、nts版,vs9表明是Visual Studio 2008 compiler編譯器編譯的,最後的x86表明的是32位的版本。
 
將下載好的php_pthreads-0.1.0-5.4-ts-vc9-x86.zip文件包解壓找到
pthreadVC2.dll和php_pthreads.dll文件.
一、修改php.ini文件 添加extension=php_pthreads.dll
二、將php_pthreads.dll放到C:\wamp\bin\php\php5.5.12\ext下面
三、將pthreadVC2.dll放到C:\wamp\bin\php\php5.5.12下面
四、將pthreadVC2.dll放到C:\Windows\System32下面
五、將pthreadVC2.dll的絕對路徑放到path環境變量裏面
三、重啓Apache服務器

多線程花的時間比單線程花的時間少的多。
