1.Notice: Undefined offset: 1 in F:wwwmy est.php on line 39，原因offset:接下去的数字是出错的数组下标,一般是超出了数组的取值范围。
2.如下文的报错原因是语法有误，没有加引号而导致的，如：define(nihao, wenwen);
Notice: Use of undefined constant nihao - assumed 'nihao' in F:www estindex.php on line 4
Notice: Use of undefined constant wenwen - assumed 'wenwen' in F:www estindex.php on line 4
wenwen
