Both Perl and PHP support string interpolation. What is string
interpolation and why is it particularly useful in the context of
web server technology?
Define the terms placeholder and bind value.
Rewrite the Perl below to use a placeholder and a bind value.
$sth = $dbh->
where fNZ=$fNZ;") or die $dbh->errstr;
$sth->execute( ) or die $dbh->errstr;
Why might the PHP below be a useful addition to one of your
validation functions? Suggest text for the user feedback
message.
elseif(strlen($suspectValue)>20) $myArr = array(false,"user
feedback message");
I kinda get what string interpolation is, I think its something to do with how to php and perl handle input from http request methods like get and post.
Apart from that im pretty stuck on this slide.
Any help on any of that stuff would be awesome and greatly appreciated
