PHP安装parsekit扩展查看opcode
PHP安装parsekit扩展查看opcode
也可以通过VLD查看，具体请看本人写的http://blog.csdn.net/21aspnet/article/details/7002644
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：

}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'));
?>
