为什么我的PHP preg_match匹配第二个子模式而不是第一个?
My PHP code is:
$pattern = '/(Sun|Mon|Tue|Wed|Thu|Fri|Sat)(,| )[\d]{1,2}[A-Z]{1,1}[a-z]{2,2}/';
if (preg_match($pattern, $content, $matches, PREG_OFFSET_CAPTURE)){
$name = str_replace("(M1) ", "", substr($content, 0, $matches[0][1]));
$date = substr($content, $matches[0][1], 15);
}
It works fine with one match sub pattern.Like:
B'Meadow Alarm Tue,17Sep 19:48 Ur001 General User Closing By User name: B'Meadow Alarm date: Tue,17Sep 19:48
My string is:
(M1) B'Meadow Alarm Tue,17Sep 19:48 Ur001 General User Closing By User (M2) B'Meadow Alarm Tue,18Nov 09:18 Ur001 General User Closing By User
it is supposed to be:
name: B'Meadow Alarm date: Tue,17Sep 19:48
But the reality result is:
name: B'Meadow Alarm Tue,17Sep 19:48 Ur001 General User Closing By User (M2) B'Meadow Alarm date: Tue,18Nov 09:18
Question: What is wrong in my pattern? or code?

Edit
Sorry, guys! One of my colleague changed this regular expression on Server's repository to following one:
'/(.*)(Sun|Mon|Tue|Wed|Thu|Fri|Sat)(,| )[\d]{1,2}[A-Z]{1,1}[a-z]{2,2}(.*)/';
But he doesn't commit to git. That is why I can't see these changes in my local repository. the (.*) cause the problem.
我的PHP代码是: p>
$ pattern ='/ (太阳|星期一|星期二|星期三|星期四|星期五|星期六)(,|)[\ d] {1,2} [AZ] {1,1} [az] {2,2} /';
if( preg_match($ pattern,$ content,$ matches,PREG_OFFSET_CAPTURE)){
$ name = str_replace(“(M1)”,“”,substr($ content,0,$ matches [0] [1])); \ n $ date = substr($ content,$ matches [0] [1],15);
}
code> pre>
它适用于一个匹配子模式。 喜欢: p>
B'Meadow Alarm Tue,17Sep 19:48 Ur001一般用户关闭用户
名称:B'Meadow Alarm
命令:星期二,17Sep 19:48
pre>
我的字符串是: p>
(M1)B'Meadow Alarm Tue,17Sep 19:48 Ur001一般用户关闭用户(M2)B' Meadow Alarm Tue,18Nov 09:18 Ur001一般用户关闭用户
pre>
它应该是: p>
name:B'Meadow 警报
date:Tue,17Sep 19:48
pre>
但实际结果是: p>
name:B'Meadow Alarm Tue,17Sep 19:48 Ur001一般用户关闭用户(M2)B'Meadow Alarm
date :星期二,18Nov 09:18
pre>
问题:我的模式有什么问题? 或代码? p>

\ 对不起,伙计们! 我的一位同事将Server的存储库中的这个正则表达式更改为以下一个:
'/(。*)(Sun | Mon | Tue | Wed | Thu | Fri | Sat)(,|)[\ d] { 1,2} [AZ] {1,1} [az] {2,2}(。*)/'; p>
但他不承诺git。 这就是我无法在本地存储库中看到这些更改的原因。
(。*)导致问题。 p>

Neither of your pattern or code is wrong. Your code output exactly as supposed to be.
