php开发之变量

环境已经搭建好了，下面就可以愉快的coding了，变量在php用到的还是比较多的，下面就介绍一些php变量的命名的一些规则：

1，所有的变量名必须以美元符号（$)开头

2，再美元符号后面的第一个字符必须为字母(A~Z,a~z) 或者下划线( _ ),不能使用数字

3，变量名剩下的部分可以包含任何数量饿字母，数字和下划线的组合

4，变量名中不能出现空格 (通常使用下划线进行文字分割)

5，变量名必须唯一

6，变量名是区分大小写的！，这意味着$varible 和$Varible是截然不同的两个变量，因此两个变量进行如此相似的命名是非常的不理智的

另外还有一些建议可以减少由于变量的命名而引起的bug

1，变量名全部使用小写字母

2，让变量名具有描述性，尽量见其名知其意

3，使用注释来说明变量的用途

4，最重要的，要保持一致的变量名

变量说完了，咱们一块学习下，双引号和单引号的区别吧， 双引号和单引号的最大的区别是，双引号内的内容可以被替换，而单引号内的内容不能够被替换，

代码如下：

<?php $string = 'abcdefg'; $result1 ='$string'; $result2 ="$string"; echo $result1;echo "************"; echo $result2; ?>

运行结果如下：
