Unable to access declared global variable in WordPress

Question

I have the following code:

$g_value = 'something'; print "$g_value"; function get_value() { global $g_value; print $g_value; } print get_value(); 

When I run it in a stand-alone PHP script, I get "somethingsomething". However, when I run it in the WordPress plugin, I only get “something” - the global declaration does not make var available in the function. I thought this should always work and is independent of register_globals or other environment settings. What's going on here?

Answer 1

 global $g_value; //declare it global even before assigning it., this should fix it. $g_value = 'something'; print "$g_value"; function get_value() { global $g_value; print $g_value; } print get_value();
