How to get day number of the week of current month's first day in PHP

Question

I want to get day number of week of the current month. For example

to day

Sep. 1st, Monday 

should return 1

Oct. 1st, Wednesday

should return 3

21.11.2014

should return 6

Answer 1

Try this:

var_dump(date('N', mktime(0, 0, 0, date('n'), 1)));

It's not clear from your question whether your input is a string or whether the function should assume the current month/year that is right now.
