The two lines that stand out are:

PHP код:

foreach(new i: Player) 


and

PHP код:

ShowPlayerDialog(playerid, DIALOG_NOTHING, DIALOG_STYLE_TABLIST_HEADERS, "Helpers Online", szDialog, "Close", ""); 


Or otherwise written as: for each player online, show the dialog again to playerid. The ShowPlayerDialog line and the headers should be outside of the loop.
