Finding date range for week for particular month and year - php

Question

Suppose I have a date available with me: 2016-07
I want to find date range of Week like this:
2016-07-03 to 2016-07-09
2016-07-10 to 2016-07-16
2016-07-17 to 2016-07-23
2016-07-24 to 2016-07-30
How can i achieve this?
I have tried using MySql but failed. Now I'm trying to do php.

This piece of code should do exactly what you want, if not please tell me or if you have questions
$date = "2016-07"; //Your date, can be any given date of this format
$monthAndYear = explode("-", $date);
$weeks = array();
$start = mktime(0, 0, 0, $monthAndYear[1], 1, $monthAndYear[0]);
$start -= 86400; //There are surely better ways
//find beginning if first week
do
{
$start += 86400;// Add one day
$tmp = date("N", $start);
}
while($tmp != 1);
//Get all weeks. If you want only those which are in the current month use this instead:
//while(date("n", ($start + 6 * 86400)) == $monthAndYear[1])
while(date("n", $start) == $monthAndYear[1])
{
$date = date("Y-m-d", $start);
$start += (6 * 86400);
$date .= " to ".date("Y-m-d", $start);
$weeks[] = $date;
$start += 86400;
}
echo "<pre>";
var_dump($weeks);
echo "</pre>";
The output is this:
array(4) {
[0]=>
string(24) "2016-07-04 to 2016-07-10"
[1]=>
string(24) "2016-07-11 to 2016-07-17"
[2]=>
string(24) "2016-07-18 to 2016-07-24"
[3]=>
string(24) "2016-07-25 to 2016-07-31"
}
With the second while option the result will be the same because the 31th is the end of the month and also the end of a week.

Please try the following code it produces the same output as yours:
function weeksRangesOfMonth($month, $year) {
$start_time = mktime(0, 0, 0, $month, 1, $year);
$start_time = mktime(0, 0, 0, $month, date('d', strtotime('First Monday', $start_time)), $year);
$end_time = mktime(0, 0, 0, $month, date('t', $start_time), $year);
$start = date("Y-m-d", $start_time);
$end = date("Y-m-d", $end_time);
for($date = $start; $date <= $end; $date = date('Y-m-d', strtotime($date. ' + 7 days'))) {
$time= strtotime($date);
$from = date("Y-m-d", strtotime('Last Sunday', $time));
$to = date("Y-m-d", strtotime('Next Saturday', $time));
echo "Start: ".$from.", End: ".$to;
echo "<br>";
}
}
weeksRangesOfMonth(7, 16);
