PHP生成Excel, 控制Excel单元格中的换行符

公司使用Mantis管理bug, Mantis有一个功能, 将bug导出为Excel,

但是目前的这个mantis版本, 在导出excel的时候, "摘要,说明,问题重现步骤说明,附加信息,评论"等等这些信息中,

提交bug时候的回车换行符都不见了, 因为没有了格式, 在excel中读起来很不方便,

?

这回想改善的便是这个问题,

在使用php做成excel的时候, 如何在一个excel cell内写入换行符, 控制该单元格的格式.

?

我试验了一下, \r\n在生成excel的时候, 是无效的, 会被过滤调.

但是要是写入
, 起到的效果不是单元格内换行, 而是换了一个新的单元格.

google了下, 要想达到单元格内换行的目的, 需要插入下面这个字符串

?

'<br style="mso-data-placement:same-cell;" />'
?

?

另外我调查的过程中, 来发现了另外一个有趣的问题.

前面已经提到, 在用php生成excel的时候, \r\n是不起任何换行作用的, 要想控制换行, 需要借助html标记.

但是, 如果把\r\n夹杂在

 
中间,

形如下面这样, 那么, 这时候的\r\n相当于一个
, 会在做成的excel中, 新起一个单元格.

写道
<br>
..........\r\n<br>
..........\r\n<br>
..........\r\n<br>
?

这种行为显然也不是我们想要的,

所以还是像下面这样, 把他们统统替换掉吧.

$p_new_lines   = array("\r\n", "\n", "\r","\r\n", "<pre class="brush:php;toolbar:false">","
","
","","
"); $p_change_line_in_excel_cell = '
'; $p_result = str_replace( $p_new_lines,$p_change_line_in_excel_cell,$p_input); ?

?

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.
