正则表达式剥离phpdoc多行注释 [英] Regex to strip phpdoc multiline comment
问题描述
我有这个:
/**
* @file
* API for loading and interacting with modules.
* More explaination here.
*
* @author Reveller <me@localhost>
* @version 19:05 28-12-2008
*/
我正在寻找一个正则表达式来剥离@token数据以外的所有数据,因此结果将是:
I'm looking for a regex to strip all but the @token data, so the result would be:
@file API for loading and interacting with modules. More explaination here.
@author Reveller <me@localhost>
@version 19:05 28-12-2008
我现在有这个:
$text = preg_replace('/\r?\n *\* */', ' ', $text);
部分完成此工作:仅删除每行前面的*。谁能帮助我,让它也删除/ **和最后的斜杠/?
It does the job partially: it only removes the * in front of each line. Who could help me so it also strips /** and the final slash /? Any help would be greatly appreciated!
PS:例如,如果commentlbock中包含
P.S: If, for instance, the commentlbock would contain something like
/**
* @foo Here's some slashes for ya: / and \
*/
然后显然@foo之后的斜杠可能不会被删除。结果必须是:
Then obviously the slashes after @foo may not be stripped. The reult would have to be:
@foo Here's some slashes for ya: / and \
我希望那里有一个正则表达式专家:-)
I hope there's a regex guru out there :-)
推荐答案
尝试
$result = preg_replace('%(\r?\n(?! \* ?@))?^(/\*\*\r?\n \* | \*/| \* ?)%m', ' ', $subject);
它将在每行的开头插入一个额外的空格,因此您可能希望去除前导空白
It will insert an extra space at the start of each line, so you might want to strip leading whitespace in a second step.
说明:
(\r?\ n(?! \ *?@))?
:如果可能,请匹配换行符,除非其后跟随 * @
(\r?\n(?! \* ?@))?
: If possible, match a newline unless it's followed by * @
^
:声明以下匹配项从行的开头开始
^
: Assert that the following match starts at the beginning of the line
(
:要么匹配
/ \ * \ * \r ?\n \ *
: / **< newline> *
|
或
\ * /
: * /
|
:或
\ *?
: *
,可选后跟另一个空格
\* ?
: *
, optionally followed by another space
)
:轮换序列的结尾
