【玩转微信公众平台之七】 PHP语法简单介绍
经过多篇的努力,我们终于成为了微信公众平台的开发者。但是别高兴的太早,就跟修真小说一样:修炼多年武破虚空,飞升到仙界后本以为成为了天仙即可跳出三界外,不在五行中。可实际到了仙界才发现,成仙只是修行的第一步......
没错,成为开发者也才只是第一步,因为现在你的微信公众平台还没有任何功能, 说难听点就是小白,说好听点就是白马王子,说可爱点就是小白白,说黄色点就是洗白白,说...
----------------
要想在微信公众平台添加功能,那就需要写代码;既然说到写代码,那么肯定是要用php(如果用ASP,Java也可以),既然说到php,那么你肯定要懂得php怎么用吧?如果懂得你可以不用往下看了,如果不懂?走起!
PHP是什么语言?PHP是一种创建爱你动态交互站点的强有力的服务器端脚本语言.......(其他请百度)。
1、首先介绍下php开发的工具,这个有很多选择,像我是直接使用Dreamweaver来开发,这个大家也都比较熟悉。
下载地址为: http://yunpan.cn/QiPjymeWbuceR 访问密码 e7df。安装过程贼简单,直接跳过。
当然了,SAE也提供了代码在线编辑功能,不过相对来说不是很方便。
2、下面简单介绍些php的语法
1)php的代码(脚本块)可以放置在文档的任何位置,但是要有个标志来提醒, 这个标志就是以""结束。例如我下面打印一个简单的字符串:hello star
<?phpecho "hello star";?>
2)php的变量。
php中所有的变量都是以 $ 符号开始的,在声明一个变量时不需要明确变量的类型,因为php会自动把变量转换为正确的数据类型。这个与C,Java等语言有很大的差别。如下:
<?php $a = 5;//相当于int a = 5$b = "this is a string";//相当于 string b = "this is a string"?>
3)php的链接操作符。
php中的连接操作符为 "."(一个英文的句号)。它可以连接字符串, 当操作数中有非字符串时,会先转换成字符串,然后再将字符串连接起来,如下代码:
<?php $a = 5;$b = 6;$c = "this is a string";echo $a . $b;//输出结果为56echo $a . $c;//输出结果为 5this is a string?>
这个东西说简单也简单,但讲起来有点烦琐,所以直接给个链接自己去看吧。( 旁白:博主,为什么你这么懒? 博主:要你管!)

5)其实掌握以上几点的话,开发一个简单的微信公众平台还是勉强够看的,剩下的内容推荐大家去w3c是这个网站上学习。上面的教程写的都很棒,是想学好php绝对不能错过的网站!
