安装parsekit扩展

http://pecl.php.net/package/parsekit

下载最新的

#wget http://pecl.php.net/get/parsekit-1.3.0.tgz

安装过程省略

可以参考  本人写的http://blog.csdn.net/21aspnet/article/details/7035392  安装apc扩展是一样的原理

还是自动安装很方便

安装:

# /usr/local/php/bin/pecl install parsekit     

配置:

php.ini加extension=parsekit.so    

重启:

# /usr/local/apache2/bin/apachectl restart  

测试:

# /usr/local/php/bin/php -r "var_dump(parsekit_compile_string('print 1+1;'));"

输出:

 再看输出hello word

# /usr/local/php/bin/php -r "var_dump(parsekit_compile_string('print \"hello word\";'));"

输出:

总结:两种方法1.如果要查看单句php的opcode

# /usr/local/php/bin/php -r "var_dump(parsekit_compile_string('print 1+1;'));"

参考 http://www.php.net/manual/zh/function.parsekit-compile-string.php


2.如果要查看网站下某个php文件的opcode

参考  http://www.php.net/manual/zh/function.parsekit-compile-file.php

# /usr/local/php/bin/php -r "var_dump(parsekit_compile_file('/var/www/tb.php'));"

 

3.如果要查看某个函数的opcode

参考 http://www.php.net/manual/zh/function.parsekit-func-arginfo.php

<span><span><?php <br /></span><span>function </span><span>foo</span><span>(</span><span>$bar</span><span>, </span><span>stdClass $baz</span><span>, &</span><span>$bomb</span><span>, </span><span>$bling </span><span>= </span><span>false</span><span>) {<br>}<br><br></span><span>var_dump</span><span>(</span><span>parsekit_func_arginfo</span><span>(</span><span>'foo'</span><span>));<br></span><span>?></span> </span>
