Question

我正在创建一个脚本，可以找到我服务器上的所有error_log文件。以下是典型error_log文件的示例：

[08-Feb-2012 05:45:56] PHP Fatal error: Uncaught exception 'Swift_RfcComplianceException' with message 'Address in mailbox given [] does not comply with RFC 2822, 3.6.2.' in /lib/SwiftMailer/classes/Swift/Mime/Headers/MailboxHeader.php:308
Stack trace:
#0 /lib/SwiftMailer/classes/Swift/Mime/Headers/MailboxHeader.php(238): Swift_Mime_Headers_MailboxHeader->_assertValidAddress('')
#1 /lib/SwiftMailer/classes/Swift/Mime/Headers/MailboxHeader.php(96): Swift_Mime_Headers_MailboxHeader->normalizeMailboxes(Array)
#2 /lib/SwiftMailer/classes/Swift/Mime/Headers/MailboxHeader.php(60): Swift_Mime_Headers_MailboxHeader->setNameAddresses(Array)
[08-Feb-2012 05:46:18] PHP Fatal error: Uncaught exception 'Swift_RfcComplianceException' with message 'Address in mailbox given [] does not comply with RFC 2822, 3.6.2.' in /lib/SwiftMailer/classes/Swift/Mime/Headers/MailboxHeader.php:308
Stack trace:
#0 /lib/SwiftMailer/classes/Swift/Mime/Headers/MailboxHeader.php(238): Swift_Mime_Headers_MailboxHeader->_assertValidAddress('')
#1 /lib/SwiftMailer/classes/Swift/Mime/Headers/MailboxHeader.php(96): Swift_Mime_Headers_MailboxHeader->normalizeMailboxes(Array)
#2 /lib/SwiftMailer/classes/Swift/Mime/Headers/MailboxHeader.php(60): Swift_Mime_Headers_MailboxHeader->setNameAddresses(Array)
[15-Feb-2012 15:39:10] PHP Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting ']' in /settings.php on line 47

我使用以下代码单独提取每个错误，以便我可以显示它们以便于查看

preg_match_all('/\[\d{2}-\w{3}-\d{4} \d{2}:\d{2}:\d{2}\].*/', $error_log_file, $error_log_parts);

它有效，但问题是没有选择多行。

Array
(
    [0] => Array
    (
        [0] => [08-Feb-2012 05:45:56] PHP Fatal error:  Uncaught exception 'Swift_RfcComplianceException' with message 'Address in mailbox given [] does not comply with RFC 2822, 3.6.2.' in /home/elvanto/public_html/lib/SwiftMailer/classes/Swift/Mime/Headers/MailboxHeader.php:308
        [1] => [08-Feb-2012 05:46:18] PHP Fatal error:  Uncaught exception 'Swift_RfcComplianceException' with message 'Address in mailbox given [] does not comply with RFC 2822, 3.6.2.' in /home/elvanto/public_html/lib/SwiftMailer/classes/Swift/Mime/Headers/MailboxHeader.php:308
        [2] => [15-Feb-2012 15:39:10] PHP Parse error:  syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting ']' in /home/elvanto/public_html/roster-settings.php on line 47
    )

)

所以我在最后加了一个's'：

preg_match_all('/\[\d{2}-\w{3}-\d{4} \d{2}:\d{2}:\d{2}\].*/s', $error_log_file, $error_log_parts);

但现在似乎选择了一切。我需要一种方法来选择一切，直到新的约会。例如：[08-Feb-2012 05:46:18]

我需要添加哪些代码才能执行此操作？

Answer 1

尝试类似

的内容

/\[\d{2}-\w{3}-\d{4} \d{2}:\d{2}:\d{2}\].*?(?=^\[)/s

.*已变为非贪婪.*?，并添加了(?=^\[)以强制.*?匹配，直到找到以{开头的换行符{1}}。

顺便说一句，您可以连续读取日志文件的行，如果看到[并且连接到当前数组条目则开始新的数组条目 - 否则您不必放屁使用\[\d{2}-\w{3}-\d{4} \d{2}:\d{2}:\d{2}\] / .*切换。

preg_match_all有多行
