PHP regular parsing Apache log file

You can scroll the logs by the hour, using the PHP regular analysis log method to solve

$logLine = ' 127.0.0.1--[22/may/2015:17:09:13 +0800] ' get/sale/images/y-select.png http/1.1 ' 1095 '; $pattern = '/^ (? P
 
  
   
  [0-9.] +) - - \[(? P
  
   [^\]]+] \]+ "GET (? P
   
    
     
    [^]+) http\/1.[ 1|0|2] "(? P
    
     
      
     [0-9.] +) (? P
     
      
       
      [0-9.] +)/I ';p reg_match ($pattern, $log, $match);//var_dump ($match); $ip     = $match [' IP ']; $time   = Strtotime ($match [ "Time"); $url    = $match [' url ']; $status = $match [' status ']; $size   = $match [' Size '];p rintf ("ip:%s Access:%s URL: %s Status:%s File Size:%s ", $ip, $time, $url, $status, $size);
     
      
    
     
   
     
 
  

And that's it.

Separating Apache log files with regular expressions
Examples of Apache log files in the Common log format:

127.0.0.1-frank [10/oct/2000:13:55:36-0700] "Get/apache_pb.gif http/1.0" 200 2326

Examples of Apache log files in the combined log format:

127.0.0.1-frank [10/oct/2000:13:55:36-0700] "Get/apache_pb.gif http/1.0" 2326 "mozilla/4.08 [en] (Win98; I; NAV) "



The IP address of the client.
The RFC1413 identity, which is determined by the client-side Identd process, indicates that the information here is not valid because of the symbol "-" in the output.
The HTTP authentication system gets the customer ID (userid) To access the page, and if the page is not password protected, this entry will be "-".
The time when the server completed the request processing.
The client's action \ Requested resource \ protocol used.
The status code returned by the server to the client.
The number of bytes returned to the client that do not include the response header. If no information is returned, this entry should be "-".
"Referer" request header.
"User-agent" request header.
The regular expression used to extract information consists of:

^: matches the beginning of each line.
([0-9.]+) \s: Match IP address.
([\w.-]+) \s: Matches an identity, consisting of a numeric letter underscore or a dot delimiter.
([\w.-]+) \s: Matches the UserID, consisting of a numeric letter underscore or a dot delimiter.
(\[[^\[\]]+\]) \s: Match time.
"((?: [^"]|\ ") +)" \s: Match request information, double quotes may appear escaped double quotation marks \ ".
(\d{3}) \s: matches the status code.
(\d+|-) \s: Matches the number of response bytes or-.
"((?: [^"]|\ ") +)" \s: Match "Referer" request header, double quotes may appear in the escaped double quotation mark \ ".
"((?: [^"]|\ ") +)": Match "user-agent" request header, double quotation marks may appear in the double quotation mark \ ".
$: Matches the end of the line.
The final expression is as follows:

^ ([0-9.] +) \s ([\w.-]+) \s ([\w.-]+] \s (\[[^\[\]]+\]) \s "((?: [^"]|\ ") +)" \s (\d{3}) \s (\d+|-) \s "((?: [^"]|\ ") +)" \s "((?: [^"]|\ ") + )"$
