If I write code that may be on a server I do not or can not control the
php.ini settings, I check for the existence of the variable before I use
it. This does increase the code size somewhat, but it makes the code
more reliable as well. If you are passing values through HTTP Post or
Get you will need something like this anyway to keep from typing the
super global variable name every time.
if (get_magic_quotes_gpc())
{
// this should not be needed, but
//some sites still use get_magic_quotes_gpc
if (array_key_exists('my_html_var', $_POST)
$my_html_var = stripslashes($_POST['my_html_var']);
}
else
{
if (array_key_exists('my_html_var', $_POST)
$my_html_var = $_POST['my_html_var'];
}
if (!is_set($my_html_var))
{
// set our variable to a known value
$my_html_var = 'somevalue';
}
Cheers,
James
