If statement help:

[ALL]

when i am echo'ing a variable to find the value or check the value, i usually write it to a test file, like so:

$handle = fopen($filename, 'a'));
fwrite($handle, "$_POST['R/W']");
fclose($handle); 

the reason i usually use a file rather than echoing the variable is because a file is more reliable to get the info out of.
