    `date('N', strtotime('First day of '.date('F').' '.date('Y')))` – Charlotte Dunois Sep 01 '14 at 20:16

    @Chad it's not duplicate. Your recommend question is for number of week day from a day and this question is no of week in sense of a month from a day. – monsur.hoq Sep 01 '14 at 21:18
  • @monsur.hoq true, there is ambiguity/distinction in the question, though the solution for the other answer is applicable to both questions. Good catch; worth an up-vote. – Chad Sep 01 '14 at 21:21

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.

$weekdayNumber = date('N', strtotime($datestring));

This returns 1:

date('N', strtotime('Sep. 1st, Monday'));

This returns 3:

date('N', strtotime('Oct. 1st, Wednesday'));

As mentioned in the comment date('N', ...) can be used to achieve this:

<?php
date_default_timezone_set('UTC');

echo date('N', strtotime('First day of month')) . PHP_EOL;
echo date('N', strtotime('Sep. 1st, Monday')) . PHP_EOL;
echo date('N', strtotime('Oct. 1st, Wednesday')) . PHP_EOL;

I suppose you actually don't know the weekday ('Monday', 'Wednesday') so all of the following would also work:

echo date('N', strtotime('Sep. 1st')); // this assumes "this year"
echo date('N', strtotime('Sep. 1st 2014'));
echo date('N', strtotime('2014-09-01')); 

echo date('N', strtotime('Oct. 1st')); // this assumes "this year"
echo date('N', strtotime('Oct. 1st 2014'));
echo date('N', strtotime('2014-10-01'));
