In the past I've seen various ways of checking the current number of online players, but all that I've seen have a fatal flaw. Depending on how the server was turned off (or more specifically, if it crashes) the player count gets messed up. Here's the one I'm talking about:; q3 ?1 U* M6 l% Z9 T: ?
Code:
5 s% ~+ @. M# U4 t$mssql = mssql_query("SELECT * FROM [ACCOUNT_DBF].dbo.[ACCOUNT_TBL] WHERE isuse='J'");8 d3 M9 P' o, o* {7 Q6 Y
echo mssql_num_rows($mssql);Here's a more proper code, which will automatically reset the current online count whenever the world server program is opened:
/ \8 j" s2 i' H* qCode:
3 r$ k/ d2 K( c  z; B( H$mssql = mssql_query("SELECT * FROM [CHARACTER_01_DBF].dbo.[CHARACTER_TBL] WHERE MultiServer='1'");5 }  }" v+ m5 y2 n2 [
echo mssql_num_rows($mssql);, c1 q9 v7 o' u2 t$ h% ~
5 s0 p8 k- F3 [4 {. B
