php正则表达式-清除文件名
我正在寻找优雅的正则表达式,以清除括号,内容看起来像文件名php正则表达式-清除文件名,php,regex,preg-replace,Php,Regex,Preg Replace,我正在寻找优雅的正则表达式,以清除括号,内容看起来像文件名 [Nibh justo] elit Nulla [link.pdf] auctor ipsum molestie (link.pdf) Condimentum euismod non [link.xls](link.xls) [link.doc](link.doc) tempus In [Curabitur] et 结果应该是: Nibh justo elit Nulla auctor ipsum molestie Condim
[Nibh justo] elit Nulla [link.pdf] auctor ipsum molestie (link.pdf)
Condimentum euismod non [link.xls](link.xls) [link.doc](link.doc) tempus
In [Curabitur] et
结果应该是:
Nibh justo elit Nulla auctor ipsum molestie Condimentum euismod
non tempus In Curabitur et
我相信一定有一条捷径可以做到这一点。
(文件的意思是简单-包括点。不需要检查句子。)
谢谢你的帮助像这样的事
$str = '[Nibh justo] elit Nulla [link.pdf] auctor ipsum molestie (link.pdf)
Condimentum euismod non [link.xls](link.xls) [link.doc](link.doc) tempus In
[Curabitur] and other [./beta/link.pfd]';
$str = preg_replace('`(\(|\[)[\w/\.-]+\.[a-z]+(\)|\])`i', '', $str);
$str = str_replace(array('[', ']'), '', $str);
echo $str;
结果是:
Nibh justo elit Nulla auctor ipsum molestie Condimentum euismod
non tempus In Curabitur and other
试试这个:
<!--
(?:[\[\(]\w+\.\w+[\]\)])|(?:[\[\(](?=[0-9A-Za-z]))|(?:(?<=[0-9A-Za-z])[\]\)])
Options: ^ and $ match at line breaks
Match either the regular expression below (attempting the next alternative only if this one fails) «(?:[\[\(]\w+\.\w+[\]\)])»
Match the regular expression below «(?:[\[\(]\w+\.\w+[\]\)])»
Match a single character present in the list below «[\[\(]»
A [ character «\[»
A ( character «\(»
Match a single character that is a “word character” (letters, digits, and underscores) «\w+»
Between one and unlimited times, as many times as possible, giving back as needed (greedy) «+»
Match the character “.” literally «\.»
Match a single character that is a “word character” (letters, digits, and underscores) «\w+»
Between one and unlimited times, as many times as possible, giving back as needed (greedy) «+»
Match a single character present in the list below «[\]\)]»
A ] character «\]»
A ) character «\)»
Or match regular expression number 2 below (attempting the next alternative only if this one fails) «(?:[\[\(](?=[0-9A-Za-z]))»
Match the regular expression below «(?:[\[\(](?=[0-9A-Za-z]))»
Match a single character present in the list below «[\[\(]»
A [ character «\[»
A ( character «\(»
Assert that the regex below can be matched, starting at this position (positive lookahead) «(?=[0-9A-Za-z])»
Match a single character present in the list below «[0-9A-Za-z]»
A character in the range between “0” and “9” «0-9»
A character in the range between “A” and “Z” «A-Z»
A character in the range between “a” and “z” «a-z»
Or match regular expression number 3 below (the entire match attempt fails if this one fails to match) «(?:(?<=[0-9A-Za-z])[\]\)])»
Match the regular expression below «(?:(?<=[0-9A-Za-z])[\]\)])»
Assert that the regex below can be matched, with the match ending at this position (positive lookbehind) «(?<=[0-9A-Za-z])»
Match a single character present in the list below «[0-9A-Za-z]»
A character in the range between “0” and “9” «0-9»
A character in the range between “A” and “Z” «A-Z»
A character in the range between “a” and “z” «a-z»
Match a single character present in the list below «[\]\)]»
A ] character «\]»
A ) character «\)»

(?:[\[\(]\w+\.\w+[\]\))))(?:[\[\(?=[0-9A-Za-z])))(?:(?:(?是的。效果很好,但库拉比图
仍然丢失。看起来它与括号中的单个单词不匹配。请尝试以下操作:(?:[\[\[\(]\w+.\w+.\w+[\]))))))(?:[\[\(?=[0-9A-Za-z]):(?感谢您的帮助。虽然文件链接包含dirs,但存在许多不匹配,但在创建expr时它有帮助。如果您需要匹配带或不带dirs的文件名
,则正则表达式可能比现在发布的更简单!
