displaying array elements on HTML file

Hi,

can someone pls help explain how I can check if a variable contains a string or if it's empty. I tried

if ($var =~ //){

do something;

}

but it seems not to actually check for empty varaibles because some varibles containing nothing where able to pass this if condition, which normally shouldn't.

Secondly, How can I get to print the values of an array to be displayed on a HTML file. E.g

@arr = qw(One Two Three Four);

print << "VAR_VALUES";
Content-type: text/html

<HTML>
<HEAD>
<TITLE>Values Entered</TITLE>
</HEAD>
<BODY>
<P><FONT SIZE=5>Here are the values entered:</FONT></P>

#How can I print the elements of the array @arr
</BODY>
</HTML>
VAR_VALUES

Thanks
