Sorry I am beginner in perl just starting hence if there are mistake please oblige.
Here is the problem
I am executing subroutine in perl script it returns me output dynamically in array format @outputArray
outputarray[0]=name ip port
outputarray[1]=------------------------------------
outputarray[2]=http-listener-1 * 6712
outputarray[3]=http-listener-2 * 4743
I can also get the output array as like below also if i want
outputarray[0]=http-listener-1 * 6712
outputarray[1]=http-listener-2 * 4743
I want to write a subroutine which will check whether port exists and if exists returns me true and the listener name if not it returns me false and null
getListenerName($porttobeChecked) This subroutine returns me the name of the listener if i pass a port. Eg: If $porttobechecked=6712 I want to return an array a[0]=TRUE and a 1=http-listener-1(listener name) If port to be checked = 4516.I want to return an array a[0]=FALSE and a 1=null .Help required

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).
