" $arryWeekDay [$dayNum] "); return $timeStamp; } echo Date ("Y-m-d L", Gettimefromweek (0)); echo " "; echo Date ("Y-m-d L", Gettimefromweek (1)); echo " "; echo Date ("Y-m-d L", Gettimefromweek (2)); echo " "; echo Date ("Y-m-d L", Gettimefromweek (3)); echo " "; echo Date ("Y-m-d L", Gettimefromweek (4)); echo " "; echo Date ("Y-m-d L", Gettimefromweek (5)); echo " "; echo Date ("Y-m-d L", Gettimefromweek (6)); echo " "; Copy Code
