Is there a way to force variable declaration (instead of implicit?) I constantly run into the problem where i misspell a variable name and it is assumed to be unitialized (null?)...
function show_results($_sql, $_query, $_first, $_n, $_max, $_show_count)
{
global $HTTP_GET_VARS;
...
if (!$_show_cnt)
{
...always does this...
}
an EXPLICIT command would force variables to be defined (var $cnt) before it is used. This is similar to commands used in various BASIC implementations.
Is there such a thing in PHP?
