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

I have a site with a contact for which has..

if (email_is_valid($youremail) && !eregi("\r",$youremail) && !eregi("\n",$youremail) && $yourname != "" && $yourmessage != "" && substr(md5($user_answer),5,10) === $answer)

The site was upgraded to php 5.3 and now users received a deprecated warning....

I know its not perl, but can someone advise what the code should now be......

I have no idea and have tried to change with pregmatch directly but fail...miserably

Please help...

    eregi("\n", $youremail) becomes preg_match("/\n/", $youremail).

    But personally, I'd replace this:

    !eregi("\r",$youremail) && !eregi("\n",$youremail)

    With this, because strpos is faster than a regexp:

    strpos("\r",$youremail)===FALSE && strpos("\n",$youremail)===FALSE

    Or even (it'll probably be faster, but it's slightly obscure):

    package Cow { use Moo; has name => (is => 'lazy', default => sub { 'Mooington' }) } say Cow->new->name
