note 33238 added to function.md5

The problem experienced by “lee at fallingforward dot net” was probably caused by using double quotes around the variable in Perl. If double quotes are used (“$pa$$”) then Perl interprets syntax symbols ($, @) as variables for lookup. In this case $$ will display the current pid for the running Perl process and not ‘$$’. To prevent this from happening you either need to escape syntax symbols or you can use single quotes (‘$pa$$') to prevent it from doing variable lookup. # Incorrect Code #-------------------------------------- $string = "pa$$"; require Digest::MD5; $md5 = Digest::MD5->new; $md5->add($string); $digest = $md5->hexdigest; print $digest,"\n"; # Correct Code #-------------------------------------- $string = ‘pa$$’; require Digest::MD5; $md5 = Digest::MD5->new; $md5->add($string); $digest = $md5->hexdigest; print $digest,"\n"; Hope this helps.
