That Caution message is not the full story, read some more on
"register_globals".
If register_globals is "On" in php.ini, then do the following:
- use session_register() to create your session variables;
- use the global variable to access the variable, not the $HTTP_SESSION_VARS
array.
Example:
$myVar = 'test';
session_register('myVar');
$myVar = 'some new value';
print $myVar;
Note: the value of $myVar is what is stored to the session at the end of the
script. And, since it is stored after the script ends, its value is not
available via $HTTP_SESSION_VARS[] until the next page.
If register_globals is "Off" in php.ini, then do the following:
- do not use session_register(), etc.
- use $HTTP_SESSION_VARS for all accesses.
Example:
$HTTP_SESSION_VARS['myVar'] = 'test';
$HTTP_SESSION_VARS['myVar'] = 'some new value';
print $HTTP_SESSION_VARS['myVar'];
