I am working on a parser for logs from a spam firewall. The format is
predictable until it reaches a certain point. It then varies greatly.
There are 2 things I want to grab from this area; the size of the
message (if it exists) and the subject (if it exists)
The line might look something like this:
- 2 39 some.text.here SZ:1825 SUBJ: A subject here
but it could also look like this:
5 6 421 Error: timeout
or this:
5 6 421 Client disconnected
All I really want is the value for each, not the prefix stuff. Which
means I still need more below, yuck.
I am doing it like this:
$remainder = explode(" ", $theLine, 18);
$s_size = '/SZ:\d+/';
$s_subject = '/SUBJ:.+/';
preg_match("$s_size","$remainder[17]",$a);
preg_match("$s_subject","$remainder[17]",$b);
if (count($a) > 0) {
$size = $a[0];
} else {
$size = 0;
}
if (count($b) > 0) {
$subject = $b[0];
} else {
$subject = "-";
}
Is there any way to clean this up a bit?
thanks.
