我如何匹配"任何组"重复为"任何组"或" ANYGROUP"
$string = "Foo Bar (Any Group - ANY GROUP Baz)
Foo Bar (Any Group - ANYGROUP Baz)";
所以他们返回" Foo Bar(Any Group - Baz)"
分隔符始终为-
这篇文章扩展了Regex/PHP Replace any repeating word group
这匹配"任何组 - 任何组"但没有空白时重复。
$result = preg_replace(
'%
( # Match and capture
(?: # the following:...
[\w/()]{1,30} # 1-30 "word" characters
[^\w/()]+ # 1 or more non-word characters
){1,4} # 1 to 4 times
) # End of capturing group 1
([ -]*) # Match any number of intervening characters (space/dash)
\1 # Match the same as the first group
%ix', # Case-insensitive, verbose regex
'\1\2', $subject);

这很难看(正如我所说的那样),但它应该有效:
$result = preg_replace(
'/((\b\w+)\s+) # One repeated word
\s*-\s*
\2
|
((\b\w+)\s+(\w+)\s+) # Two repeated words
\s*-\s*
\4\s*\5
|
((\b\w+)\s+(\w+)\s+(\w+)\s+) # Three
\s*-\s*
\7\s*\8\s*\9
|
((\b\w+)\s+(\w+)\s+(\w+)\s+(\w+)\s+) # Four
\s*-\s*
\11\s*\12\s*\13\s*\14\b/ix',
'\1\3\6\10-', $subject);

最多6个字的解决方案是:
$result = preg_replace(
'/
(\(\s*)
(([^\s-]+)
\s*?([^\s-]*)
\s*?([^\s-]*)
\s*?([^\s-]*)
\s*?([^\s-]*)
\s*?([^\s-]*))
(\s*\-\s*)
\3\s*\4\s*\5\s*\6\s*\7\s*\8\s*
/ix',
'\1\2\9',
$string);
