That was my first thought also. I was just curious if it was faster than s/^\s+|\s+$//g;
use Benchmark;
my $val = " Smart Way ";
timethese(1000000, {
regex1 => sub {
my $tmp = $val;
$tmp =~ s/^\s*(.*?)\s*$/$1/g;
},
regex2 => sub {
my $tmp = $val;
$tmp =~ s/^\s+//;
$tmp =~ s/\s+$//;
}
});
__OUTPUT__
Benchmark: timing 1000000 iterations of regex1, regex2...
