or even with a match:
#!/usr/bin/perl use strict; use warnings; my %factories = ( 'farms' => 'horses'); my $tmpf = 'farms'; my $match = "horses on the farm!"; print "$tmpf\n"; # prints 'farms' print keys( %factories), "\n"; # 'farms' is one of them. if ( defined $factories{$tmpf} ) { print "yay!\n" if $match =~ m/$factories{$tmpf}/; }
farms farms yay!

to ask a question is a moment of shame
to remain ignorant is a lifelong shame

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • 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.
