Php datetime set_ day to 1

$date = date_create['2013-10-27'];// This is the date that inputed in textbox and that format is [Y-m-d]

$date = date_create['2013-10-10'];// and if i click the button i want to force change the 27 to 10?

Should i use date_modify and do some loop or there's other way to change it in easy way rather than looping.

$in = date_create['2013-10-27'];

// example 1
$out = date_create[$in->format['Y-m-10']];
echo $out->format['Y-m-d'] . "\n";

// example 2
$out = clone $in;
$out->setDate[$out->format['Y'], $out->format['m'], 10];
echo $out->format['Y-m-d'] . "\n";

// example 3
$out = clone $in;
$out->modify[[10 - $out->format['d']] . ' day'];
echo $out->format['Y-m-d'] . "\n";

Demo.

You can use the native PHP "date_date_set" function to make this change.

$date = date_create['2013-10-27'];
echo $date->format['Y-m-d'];
2013-10-27
date_date_set[$date,
              date_format[$date, 'Y'],
              date_format[$date, 'm'],
              10];
echo $date->format['Y-m-d'];
2013-10-10

Or using the Object-Oriented style:

$date = new DateTime['2013-10-27'];
echo $date->format['Y-m-d'];
2013-10-27
$date->setDate[$date->format['Y'], $date->format['m'], 10];
echo $date->format['Y-m-d'];
2013-10-10

$date = date["Y-m-d", strtotime["2013-10-10"]];

Updated: to force to change the day from 27 to 10

1] get the year and month

$date = date["Y-m-", strtotime[ $_POST['user_selected_date'] ]];

2] append your day

$date .= '10';

Also you can finish it in ONE step $date = date["Y-m-10", strtotime[ $_POST['user_selected_date'] ]];

Note: If you're just trying to modify the value of a day on the date that comes from a submitted from a . You could try these steps:

$date = '2013-10-27'; // pass the value of input first.

$date = explode['-', $date]; // explode to get array of YY-MM-DD

//formatted results of array would be
$date[0] = '2013'; // YY
$date[1] = '10';   // MM
$date[2] = '17';   // DD

// when trigger a button to change the day value.

$date[2] = '10'; // this would change the previous value of DD/Day to this one. Or input any value you want to execute when the button is triggered

// then implode the array again for datetime format.

$date = implode['-', $date]; // that will output '2013-10-10'.

// lastly create date format

$date = date_create[$date];

Use PCRE Function

$date = '2013-10-27';
$new_date = preg_replace["/\d{2}$/", "10", $date];
