I use the following statements:

$var = "";
$var = $_POST('varname');

In php 4, when 'varname' was not defined, $var remained an empty string;
In php 5, I suddenly get errors.

I solved these by including the function array_key_exist to check the
occurence of 'varname'
Is this the prefered way or is ther a better solution?

Thanx,
Han koster
