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\";'));"

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

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