Processing log files with PHP regular expressions - php

Question

Im going through a log file using php and it looks either like this:
11/06/05 09:17:59 TORMS068 11/06/05 09:17:59.234 TORMS068\Admin ... EPTH{2} ITEMIX{8} TELL{`` sdcsit49 - FileSystem /oracle/REF/sapdata2 Critical - MSGREC:1727:100 ``} USE{TELL} ATTACHMENT... xact{`NO`}
Where I used Ellipses to show there were a lot of other stuff
OR like this
11/06/05 11:29:38 TORM ... H{3} ITEMIX{5} TELL{``marble: initiator SCSI ID now 7 } File={ /var/adm/messages } - MsgRec 5174:406``} USE{TELL} ATTACHMENT{} UserParms{} AnswerWait{`10`} BaudRate{`1200`} C... eviceId{``} TellExact{`NO`}
So it is either followed by a USE{TELL} or File={.*}
I want to extract what is in the {}'s for TELL{} for every line in the log file..
Please help me, I'm going crazy lol
Thanks

Answer 1

if (preg_match("/USE\{(?<insideTheBrackets>[^\}]+)\}/", $line, $pat)) {
var_dump($pat['insideTheBrackets']);
}

Answer 2

PHP's regular expression documentation is pretty good at explaining this stuff...
<?php
$str = "11/06/05 11:29:38 TORM ... H{3} ITEMIX{5} TELL{``marble: initiator SCSI ID now 7 } File={ /var/adm/messages } - MsgRec 5174:406``} USE{TELL} ATTACHMENT{} UserParms{} AnswerWait{`10`} BaudRate{`1200`} C... eviceId{``} TellExact{`NO`}";
$pat = '/TELL{(``.*``)}/';
preg_match($pat,$str,$matches);
print_r($matches);
?>

Well I couldn't get a reliable method to work, but what I ended up with was
if (preg_match("/(TELL{)(.*)} (USE{T)/iU ",$data,$matches))
$rowMsg=substr($matches[0],5,-7);
$rowMsg=preg_replace("/[}\. ]{1}\$/",'',$rowMsg);
