I am using this.

<?php

function weeks($month, $year){
    $firstday = date("w", mktime(0, 0, 0, $month, 1, $year)); 
    $lastday = date("t", mktime(0, 0, 0, $month, 1, $year)); 
    $count_weeks = 1 + ceil(($lastday-7+$firstday)/7);
    return $count_weeks;
}

echo weeks(11,2016)."<br/>";

?>

Result:

if I wanted to start the first week as the first sunday of the month? – Earvin Nill Castillo Nov 23 '16 at 05:23
Like what? The code is fine with Sunday as the first day of the week. The same as for month. – Irvin Nov 23 '16 at 05:28
since nov 1 is tuesday, therefore the first sunday of month must be nov 6 – Earvin Nill Castillo Nov 23 '16 at 05:33
I have been looking around for this and I believe this is the simplest working code I could find!!! – Umar Niazi Dec 21 '22 at 02:12

Using a Simple DateTime() Class as shown below could do. Just change the Value of the $anyDate Variable to suit whatever Date you prefer and you are good to go. The $weekNum will be the Week Number corresponding to the provided Date ($anyDate) Quick-Test Here.

<?php

    $anyDate    = "2016-11-22";
    $objDT      = new DateTime($anyDate);
    $weekNum    = $objDT->format('W');     //<== RETURNS THE WEEK NUMBER OF $anyDate

    var_dump($weekNum);                    //<== YIELDS:: string '47' (length=2)

On the other hand, if you are interested in the Week of the Month in the Context of the current Date (that is, as in: the 3rd Week of November or something similar); you could modify your code as shown below. Quick Test Here.

<?php
    $firstDayOfMonth    = "2016-11-01";
    $currentDate        = "2016-11-22";
    $dtCurrent          = new \DateTime($currentDate);
    $dtFirstOfMonth     = new \DateTime($firstDayOfMonth);
    $numWeeks           = 1 + ( intval($dtCurrent->format("W")) - 
                                intval($dtFirstOfMonth->format("W")));

    var_dump($numWeeks);             //<== YIELDS:: int 4    
                                     //<== 22ND IS THE 4TH WEEK IN THE MONTH OF NOVEMBER   

                                     //<== ONE CAN EQUALLY READ IT THUS: 22ND FALLS INTO 
                                     //<== WEEK NR. 4 IN THE MONTH OF NOVEMBER

Cheers and Good-Luck

I think what OP wanted is to count the `number of weeks` in the current month not the `week number of the year`. — Irvin, Nov 23 '16 at 03:26
Ahhhhaaa..... You might be right @Irvin.... Perhaps, one could also add that as an alternative... but ***Thanks, anyways for pointing out the probability...* ;-)** — Poiz, Nov 23 '16 at 03:31
$date = date('Y-m-d'); $newdate = strtotime ( 'W', strtotime ( $date ) ) ; $newdate = date ( 'W' , $newdate ); echo $newdate; — Earvin Nill Castillo, Nov 23 '16 at 05:20
