understanding global variables

[Anon]

hi,

i thought that $<var_name> and $GLOBALS["<var_name">] are synonyms. but it seems that i missunderstand something.

i have the following code

print($g_curElem->m_szName . '<br>');
print($GLOBALS["g_curElem"]->m_szName . '<br>');

and i get a different output. this code is in a function, where $g_curElem is declared as global

what's my problem???

thanX

Well, the $GLOBALS[] array holds, like you say, all the global variables. However, an object is not a variable! You can place a pointer to an object in an array, but not the object itself. The "easy" solution is to declare the object global in the start of your function, as you mentioned.
