Question 2: How to convert PHP string to DateTime

<?php 
$input = '05/21/2011 15:00:03'; 
$date = strtotime($input); 
echo date('d/M/Y h:i:s', $date); 
?>

<?php

$input = '05/21/2011 15:00:03';

$date = strtotime($input);

echo date('d/M/Y h:i:s', $date);

21/May/2011 03:00:03

1	21/May/2011 03:00:03

Note: therefore, in PHP string to date, When we use “D” in the place of “d” for getting the day in the output, let’s see below.

<?php 
$input = '03/9/2011 15:00:03'; 
$date = strtotime($input); 
echo date('D/M/Y h:i:s', $date); 
?>

<?php

$input = '03/9/2011 15:00:03';

$date = strtotime($input);

echo date('D/M/Y h:i:s', $date);

Wed/Mar/2011 03:00:03

1	Wed/Mar/2011 03:00:03

Note: Furthermore, when we use “H” in the place of “h” for getting the time in 24 Hours format in the output, let’s see below.

<?php 
$input = '02/9/2011 15:00:03'; 
$date = strtotime($input); 
echo date('D/M/Y H:i:s', $date); 
?>

<?php

$input = '02/9/2011 15:00:03';

$date = strtotime($input);

echo date('D/M/Y H:i:s', $date);

Wed/Feb/2011 15:00:03

1	Wed/Feb/2011 15:00:03

Note: Similarly, the “i” and “s” could also be changed to uppercase to find different outputs, it is possible but not of much use.

Question 3: How to Converting PHP string to Date and DateTime

Therefore, you will be used strtotime() on your first date then date('Y-m-d') to convert it back:

<?php 
$time = strtotime('10/16/2003');
$newformat = date('Y-m-d',$time);
echo $newformat;
// 2003-10-16
?>

<?php

$time = strtotime('10/16/2003');

$newformat = date('Y-m-d',$time);

echo $newformat;

// 2003-10-16

Note: You can notice that there is a difference between using forward slash / and hyphen – in the strtotime() function.
Dates in the d-m-y or m/d/y formats are disambiguated by looking at the separator between the various components:
furthermore, if the separator is a dash (-) or a dot (.), then the European d-m-y format is assumed.
whereas if the separator is a slash (/), then the American m/d/y is assumed;

$start_date=strtotime("Tuesday");

$end_date=strtotime("+7 weeks", $start_date);
