Hi Monks,
My code is like this:
$sop = xx
#$sop read from user input
#$sop is <,>,>=,<=,==,!=
$sport = xx
#$sport read from user input
#$sport is tcp or udp port
$code = "if($port_a $op $port_b ){";
$code .= "$result =1;}";
$code .= "else{$result=0;}";
while(<FH>)
{
@tmpdata = split /:/;
$port_a = $tmpdata[8];
$op = $sop;
$port_b = $sport;
eval $code;
if ($result)
{
#do something
}
else
{
#do something
}
}
But perl don't support that . So I must use like that:
while(<FH>)
{
@tmpdata = split /:/;
if ( ($sop eq "<") and ($tmpdata[8]<$sport ) )
{
#do something
}
elsif( ($sop eq ">") and ($tmpdata[8]>$sport )
{
#do something
}
#and other op like <=,>=,==,!=
}
So are there any more efficient way to do that ?
my last question related How to use eval?
thanks!
Edited by BazB: fixed link to use Perlmonks tags

Are you posting in the right place? Check out Where do I post X? to know for sure.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

Want more info? How to link
or How to display code and escape characters
are good places to start.
