See:
FIND_MATCH:
{
foreach my $a (@array)
{
if( $hash{$a} eq 'correct_value' )
{
print 'Success';
last FIND_MATCH;
}
}
warn "Didn't find a suitable match!";
}
By targeting the last at the outer block, if you find a match, you completely exit that block. Otherwise, if you make it all the way through the foreach loop without a match, you will hit the warning message right before exiting the block.

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).
