搜索[]并替换它之间的所有内容 [英] Search for [ ] and replace everything between it

问题描述

我有一个使用结构
[FIRSTNAME]
[LASTNAME]

等等的模板文件....我会正在进行搜索并替换它。我想要做的一件事是，当模板被发回时，如果我没有规定，[FIRSTNAME] ....它仍然显示在模板中...我想使它成为空如果我避难'$ t
$ b

在我的代码中我使用FILE_GET_CONTENTS

  $ q = file_get_contents（$ filename）; 
 foreach（$ this-> dataArray as $ key => $ value）
 {
 $ q = str_replace（'['。$ key。']'，$ value，$ q）; 
} 
 return $ q; 
  

因此，一旦循环结束填写正确的数据，我需要再次搜索并替换任何使用的变量，[FIRSTNAME]

我希望这是有道理的，任何人都可以引导我朝着正确的方向前进。

干杯

解决方案

听起来就像你只想添加一行：

  $ q = preg_replace（'/ \ [[^ \]] * \] /'，''，$ q）; 
  

完成所有定义的替换后，删除任何剩余的方括号内的字词。
$ b

如果您想简明扼要，您可以用 http://www.webmasterworld.com/php/3444822.htm ，用方括号代替curlies。

I have a template file that uses the structure [FIRSTNAME] [LASTNAME]

etc etc.... and I will be doing a search and replace on it. One thing that I would like to do is that when the template get's sent back, IF I haven't stipulated, [FIRSTNAME].... it still shows in the template... I would like to make it NULL IF I haven't stipulated any data to that variable.

in my code i'm using the FILE_GET_CONTENTS

$q = file_get_contents($filename);
foreach ($this->dataArray as $key => $value) 
{
    $q = str_replace('['.$key.']', $value, $q);
}
return $q;

So once that loop is over filling in the proper data, I need to do another search and replace for any variables left using, [FIRSTNAME]

I hope this makes sense any someone can steer me in the right direction.

Cheers

解决方案

It sounds like you just want to add a line like:

$q = preg_replace('/\[[^\]]*\]/', '' , $q);

After all your defined substitutions, to eliminate any remaining square-bracketed words.

If you want to be concise, you can replace the whole function with a variation of the "one line template engine" at http://www.webmasterworld.com/php/3444822.htm, with square brackets instead of curlies.
