- #length EXPR
- #length
-
Returns the length in characters of the value of EXPR. If EXPR is omitted, returns the length of
$_. If EXPR is undefined, returnsundef.This function cannot be used on an entire array or hash to find out how many elements these have. For that, use
scalar @arrayandscalar keys %hash, respectively.Like all Perl character operations,
lengthnormally deals in logical characters, not physical bytes. For how many bytes a string encoded as UTF-8 would take up, uselength(Encode::encode('UTF-8', EXPR))(you'll have touse Encodefirst). See Encode and perlunicode.
