php手册怎么看

每次有新手来问问题,我发现其实很大一部分都是没有仔细阅读手册。

对于新手来讲。我觉得“会看”手册是样很重要的技能。

相信大家有和我做新手时有同样的感觉,手册看完和没看差不多…

1、看不懂手册(不知道从哪开始看,应该先看哪)

2、稍微看明白点了不会用(不知道方法怎么使用,写在哪里,报各种错不会解决)

3、看完记不住(看完和没看差不多,除非死记硬背记住函数,下次在索引里搜索)

可能大家还有别的问题,大家可以说出来咱们在一起研究~

欢迎大佬们狂喷,大佬们喷完我们菜鸟才能进行改正和进步~

那么我们一起来涨姿势吧!!(这里我们用php手册举例)

php手册怎么看

什么是手册?

相信大家从小到大没少看,我觉得手册就是说明书,像我们小时候组装赛车的图纸一样。

手册到底该怎么看?

很庆幸,听见yolo大神说,没事的时候多翻翻手册,我也不知道怎么看。就从头开始,一个一个目录的看,直到看见了,如何阅读函数的定义

php手册怎么看

手册写的真的很明白,只是咱们新手只想着怎么快点学怎么多学点,一路狂奔,而却忘了最基础的,说明书都看不懂,还组装什么四驱赛车。我只想强调一点,手册真的很重要,要看和自己版本相对的手册。

解决第1个问题:不知道从哪开始看

先看一遍目录,一个一个展开的看,如果有教怎么看手册的再好不过了(如上图)

解决第2个问题:看见函数不会用

首先根据函数的定义我在啰嗦一遍

例子1:fopen()函数,你知道这是打开文件的函数,但是里面还有一堆隐性知识呢,你知道吗?

例子2:参数带&是怎么回事

php手册怎么看

解决第2个问题:函数写在哪里是根据逻辑来判断的

php手册怎么看

所谓逻辑:我的理解是按照事物的正常发展顺序从上到下(如:程序就是从上到下)或从左到右(调类库中的方法或这个这个类调那个类)的依次执行(按照顺便一步不差的执行)

解决第2个问题:报各种错不会解决需要一步一步分析,我这里提供几个我个人的心得

1、先把错误翻译过来,知道大概是啥意思(偷偷的告诉你,灵格斯词典专业翻译it单词哦)

2、把代码从你感觉出问题的地方开始打印,一步一步打印,看看问题大概出在哪

3、上百度

4、回家(去群里)喊大神帮忙

返回值怎么用?这里我们可以利用bool量返回值和本例打开文件失败返回false来干2件事(上上上图所说的2)

1、调试错误

php手册怎么看

2、逻辑判断

解决第3个问题:看完记不住

for(i=0;i<无穷次;i++){echo  “解决之道:多看多用,在多看多用”;echo  “相信勤能补拙、孰能生巧 ”;}

其实有2个方法啦

1、记住目录结构中的大体内容就O啦

函数参考-》目录怎么看

php手册怎么看

3级目录打开后的介绍:

简介:这个扩展是干什么用的,看不懂就百度

需求:此扩展有没有什么依赖(编译安装才用考虑)

安装:此扩展不需要安装,编译安装时,这个扩展通过哪个参数安装

配置:安装完之后需不需要修改php.ini的配置

预定义常量:其实是给函数的形参用的啦

php手册怎么看

如何快速查阅:细心的朋友们观察一下,每次点击字典都是字典名里包含的文件目录

php手册怎么看

2、如想查和操作文件相关的函数,即使只记住一个f字母,在索引那搜,看着哪个像点哪个,点完之后,将手册从索引切换到目录
