程序功能是服务器和客户端之间TCP通信。

/******update ana[i].id's phnum by id in buffer******/

ana[i].phnum = oodbget_ph(analog_descr,ana[i].id);

/******then get new value by ana[i].id's new phnum******/
ret = oodbread_rph((void*)tempana_buf,ana[i].phnum,analog_descr,sizeof(ANALOG));
if( ret == OO_FAIL)
{
fprintf(fp_error,"get new ANA value is failed!!\n");
fprintf(fp_error,"the wrony ANALOG phnum is %d......id is %s\n",ana[i].phnum,ana[i].id);
fflush(fp_error);
continue;

就是看不懂这里的phnum是代表什么，
