两个句子的区别

一样的！any用于否定句，表示任何一个的意思。

后面那句是全部否定。

1.not all+名词,all...not,not...all表示部分否定

2.no+名词表示全部否定

举个例子：

Not all birds can fly.

本句=All birds can not fly=Some birds can’t fly=不是所有的鸟都会飞——部分否定

No birds can fly.=Birds can’t fly.----全部否定

3.英语中 all ， both， every， everyone， everything 等与否定词 not 连用时，表示的是部分否定，例如：

I don't know all of them. 我并不全认识他们。

I don't like both of the books. 这两本书我并不都喜欢。

Not every student goes to the farm on Sundays. 并非每个学生星期天都去农场。

Not everyone in our class likes football. 在我们班并非每个人都喜欢足球。

4.若要表示全部否定，则应用相应的表示全部否定的否定词。如： all → none （一个人也没有、没有任何东西）， both → neither （两个都不）， every → no， everyone → no one（nobody）， everything → nothing 等。上述四个例句要表示全部否定应分别为：

I know none of them. 他们我都不认识。

I like neither of the books. 这两本书我都不喜欢。

No student goes to the farm on Sundays. 星期天没有学生去农场。

No one/ Nobody in our class likes football. 我们班没有人喜欢足球。

出现“PHP Warning: mysqli_fetch_array() expe”是什么原因啊？

首先都是表示失望 (someone/ something is not as good as you expeted)。

1. One very relevant quote from the M-W Dictionary of English Usage:

"When disappointed is used with a preposition in contemporary writing, it may take any one of several prepositions: about, at, by, in, over or with. At one time, disappointed of was common, but during the 20th century, disappointed in has become the most prevalent usage."

2.

This is an abstract from Longman Contemporary Dictionary and I think it's clear enough:

Disappointed:

unhappy because something you hoped for did not happen, or because someone or something was not as good as you expected:

E.g:Dad seemed more disappointed than angry. disappointed customers

Disappointed at/with/about

E.g:Local residents were disappointed with the decision.

disappointed (that)

E.g: I was disappointed that we played so well yet still lost.

disappointed in

E.g: I’m very disappointed in you.

disappointed to hear/see/find etc

E.g: Visitors were disappointed to find the museum closed.

原因是：sql语句出错，你直接执行以下sql语句，就知道有地方出现错误了，

mysqli_fetch_array()这个函数需要内容才能输出，如果sql语句出错了，就没有内容了，就出现警告了。

PHP显示严重的错误主要有：

1、1E_ERROR 致命的运行时错误。

2、2E_WARNING 运行时警告(非致命性错误)。

3、E_PARSE 编译时解析错误。

4、8 E_NOTICE 运行时提醒(经常是bug，也可能是有意的)。

5、16 E_CORE_ERROR PHP启动时初始化过程中的致命错误。

6、32 E_CORE_WARNING PHP启动时初始化过程中的警告(非致命性错)。

7、64 E_COMPILE_ERROR 编译时致命性错。

8、128 E_COMPILE_WARNING 编译时警告(非致命性错)。

9、256 E_USER_ERROR 用户自定义的致命错误。

10、512 E_USER_WARNING 用户自定义的警告(非致命性错误)。
