Re: How to get the number of fields found by split without a warning?

As you've probably read, split returns an array, so I'd recommend you take advantage of that and afterwards count the number of elements in the array.

my $str = "a,b,c,d,e";
my @n = split ',', $str;
print "There were " . ($#n+1) . " elements.\n";

The '+1' is required because array offsets start at zero.

Update: Or, as Corion pointed out, scalar(@n) which is much clearer.

Dittos to talexb, but I like scalar: `use strict; my $str = "a,b,c,d,e"; my @n = split /,/, $str; print scalar @n, "\n"` [download] Hanlon's Razor - "Never attribute to malice that which can be adequately explained by stupidity"	[reply] [d/l]
