|

* 3. switch case/default 后面没有break时，后面行indent还原；
|
||
* 4. switch 多个case/default并列，没有break时；后面indent处理
|
||
* 5. +-/*.&^|%后面跟等号运算符；等号不加空格
|
||
* 6. 块级字符串；结束标记无indent;否则语法错误
|
||
* 7. if/else {前后多余空行去除；
|
||
* 8. try cache 中cache不换行；同else
|
||
* 9. --表达式含有{}不换行; 形如:ord($text{strlen($text)-1}); 冲突:导致行注释后括号变成注释导致语法错误;
|
||
* 10. 多行注释；注释内容不做修改
