looking for a regex to see if string contains '342' in it anywhere...

[spewn]

basically i want this:

string='574678957895724343268746934687';

and i want to see is 342 pattern exists anywhere in there.

any ideas?

[DotSlashJames]

print $string =~ /342/ ? 'yes' : 'no';

 

[spewn]

so this works?

if ($string =~ /$offerID/) {print 'match';}

seems to match when isn't true sometimes. $offerID format is 1234, or 1345|2545|6777.

Are you trying to match a literal pipe (|) in 1345|2545|6777, or is that an alternation (or) operator? If it's the former (literal), you'll need to backslash it so Perl doesn't interpret as alternation.

If that doesn't straighten it out (or I'm not making myself clear), post some code with some sample input.

$string='574678957895724343268746934687';

if( $string =~ /342/ ){
[tab]print "match\n";
} else {
[tab]print "no match\n";
}

If you're only matching literal strings, it's easier to use the `index' function, rather than firing up the regexp engine (plus you don't have to worry about special regexp characters, not that that's a particularly onerous task either):

my $string = '574678957895724343268746934687';
my $offer_id = '342';
if ( index( $string, $offer_id ) >= 0 ) {
  print "match\n";
}
else {
   print "no match\n";
]
