Number of days of the week in a loop (the red letter shows the number of days of the week)
$ Week_array = array (1, 2, 3, 4, 5, 6, 7 );

Foreach ($ week_array as $ key => $ value)
{
If ($ value = date ("W "))

$ Value = "<font color =" red ">". $ value. "</font> ";

The number of days in the current month is output cyclically (the red letter shows the current number)
For ($ day = date ("T"); $ day> 0; $ day --)

Sort ($ month_array );
Foreach ($ month_array
$ Key => $ value)
{
If ($ value = date ("J "))
$ Value = "<font
Color = "red"> ". $ value." </font> ";
Echo $ value ."";
} Echo
'Month of the current year :';
For ($ I = 1; $ I <= 12; $ I ++ ){
If ($ I = Date ('n') echo '<B
Style = "color: Red"> ';
