关于语言中的warning(包括PHP中的notice)的问题,warningnotice

PHP的notice

今天在用PHP写一个文件读写的问题,截取里面的数据会有notice,如下,(不影响运行)。由于自己没有在公司内部做过PHP的产品,也不知道对notice的要求是什么?于是到百度GOOGLE求答案,都是对各种notice的处理。

与其他PHP技术人员讨论,怎么处理的都有:有说全部都处理的;有说直接@的;有说直接改报告错误级别的。

C++的warning

同时想到了C++程序中的warning的如下,以前写的小模块waring都是处理掉的。现在公司不要求对waring进行处理,也就没有做处理,毕竟是需要时间的吗?

总结

自己写程序的时候不喜欢看到有warning或notice啥的出现,所以都会进行处理,在一个不要求处理的公司内有时因为堕性,就不处理了,有时这种waring是他人程序内的。

你们是怎么处理的呢?

php中的notice问题

不知道你的 php.ini 怎么改的。。或者说。。改对文件了没有(别肯定太快,我常见N多人都是改错文件的)

实在不行的话。你在你代码的每个文件或者通用文件第一行写上这个

error_reporting(E_USER_ERROR | E_USER_WARNING | E_USER_NOTICE);
 

PHP新手问题: 如果有用到资料库,网站会有好多warning与notice

问题1:只是个提示,说mysql_pcconect()这个函数会在未来的php版本中取出,请使用mysqli或者pdo替代
问题2:代码第139行的rs_admin这个变量没有定义,这个你自己检查一下
问题3:由于问题2的缘故,导致你的mysql_free_result()的参数为null,解决问题2这里就没问题了

如果你只是想隐藏问题的话(不推荐):
在你的php文件开头添加:
ini_set('display_errors',"1");
