strlen like function in perl

blax has asked for the wisdom of the Perl Monks concerning the following question:

Hello,

Is there a function like C's strlen in perl? I have been counting strings like this:

my $string = "2002023884ks293jjksd"
for ($x = 0; $string =~ /(.)/g; $x++) {
    ;
}
[download]

Which is working out just fine. If there is not a strlen like function, is there a better way to do it?

Thanks in advance,
blax

You're looking for length. update: Though, if golf is what you want, I've heard `y///c` be used to get the length of `$_`. (It's one character shorter. And, IIRC, that trick is credited to Abigail.) (`y///c` or any of its equivilents is not reccommended for code you plan on actually using, of course.)	[reply] [d/l] [select]

As others said already, your answer's the length() function, used thusly: `$x = length $string;` [download] You might want to check out some of the resources linked from this node: For Beginners: Basic Information Resources (or, Where to Look Things Up). andy.	[reply] [d/l]

Just another solution: `$length=$string=~y///c` [download] Yet another solution: `$length = scalar split /\|/,$string` [download]	[reply] [d/l] [select]
