I'm not sure that your construct will work; however, you could always do
echo $HTTP_POST_VARS[$table_array[$iCnt][0]];
in place of 'echo $$var' or
$var = 'HTTP_POST_VARS';
echo ${$var}[$table_array[$iCnt][0]];
When using variable variables, the array index - here, 'ld_val' might
not be interpreted correctly; I'm guessing that PHP is looking for a
variable named 'HTTP_POST_VARS["ld_val"]', not an element of the
HTTP_POST_VARS array. More info is at
http://www.php.net/manual/en/language.variables.variable.php
On the other hand, are you absolutely sure that something (other than
whitespace) is actually IN $HTTP_POST_VARS['ld_val'] ??
