php中出现“Call to a member function Execute() on a non-object”的问题

没得办法,学艺不精,今天使用php+adodb进行数据库操作的时候出现“Call to a member function Execute() on a non-object”错误。搞了半天,终于晓得了,在php自定义函数中使用了全局变量,但是没有使用global语句在函数的开头进行声明。php使用变量是不需声明的,因此在函数中使用我想用的那个全局变量的时候,实际上默认创建了一个同名的局部变量,这样,出现错误就是很正常的了。嘿嘿,global一下,下次,你也记住哦~
