Convert a date format in PHP
PhpDateFormattingPhp Problem Overview
I am trying to convert a date from yyyy-mm-dd
to dd-mm-yyyy
(but not in SQL); however I don't know how the date function requires a timestamp, and I can't get a timestamp from this string.
How is this possible?
Php Solutions
Solution 1 - Php
Use strtotime()
and date()
:
$originalDate = "2010-03-21";
$newDate = date("d-m-Y", strtotime($originalDate));
(See the strtotime and date documentation on the PHP site.)
Note that this was a quick solution to the original question. For more extensive conversions, you should really be using the DateTime
class to parse and format :-)
Solution 2 - Php
If you'd like to avoid the strtotime conversion (for example, strtotime is not being able to parse your input) you can use,
$myDateTime = DateTime::createFromFormat('Y-m-d', $dateString);
$newDateString = $myDateTime->format('d-m-Y');
Or, equivalently:
$newDateString = date_format(date_create_from_format('Y-m-d', $dateString), 'd-m-Y');
You are first giving it the format $dateString is in. Then you are telling it the format you want $newDateString to be in.
Or if the source-format always is "Y-m-d" (yyyy-mm-dd), then just use DateTime:
<?php
$source = '2012-07-31';
$date = new DateTime($source);
echo $date->format('d.m.Y'); // 31.07.2012
echo $date->format('d-m-Y'); // 31-07-2012
?>
Solution 3 - Php
Use:
implode('-', array_reverse(explode('-', $date)));
Without the date conversion overhead, I am not sure it'll matter much.
Solution 4 - Php
$newDate = preg_replace("/(\d+)\D+(\d+)\D+(\d+)/","$3-$2-$1",$originalDate);
This code works for every date format.
You can change the order of replacement variables such $3-$1-$2 due to your old date format.
Solution 5 - Php
$timestamp = strtotime(your date variable);
$new_date = date('d-m-Y', $timestamp);
For more, see the documentation for strtotime
.
Or even shorter:
$new_date = date('d-m-Y', strtotime(your date variable));
Solution 6 - Php
Also another obscure possibility:
$oldDate = '2010-03-20'
$arr = explode('-', $oldDate);
$newDate = $arr[2].'-'.$arr[1].'-'.$arr[0];
I don't know if I would use it but still :)
Solution 7 - Php
There are two ways to implement this:
$date = strtotime(date);
$new_date = date('d-m-Y', $date);
2.
$cls_date = new DateTime($date);
echo $cls_date->format('d-m-Y');

The most voted answer is actually incorrect!
The PHP strtotime manual here states that "The function expects to be given a string containing an English date format". What it actually means is that it expects an American US date format, such as "m-d-Y" or "m/d/Y".
That means that a date provided as "Y-m-d" may get misinterpreted by strtotime
. You should provide the date in the expected format.
I wrote a little function to return dates in several formats. Use and modify at will. If anyone does turn that into a class, I'd be glad if that would be shared.
function Date_Converter($date, $locale = "br") {
# Exception
if (is_null($date))
$date = date("m/d/Y H:i:s");
# Let's go ahead and get a string date in case we've
# been given a Unix Time Stamp
if ($locale == "unix")
$date = date("m/d/Y H:i:s", $date);
# Separate Date from Time
$date = explode(" ", $date);
if ($locale == "br") {
# Separate d/m/Y from Date
$date[0] = explode("/", $date[0]);
# Rearrange Date into m/d/Y
$date[0] = $date[0][1] . "/" . $date[0][0] . "/" . $date[0][2];
}
# Return date in all formats
# US
$Return["datetime"]["us"] = implode(" ", $date);
$Return["date"]["us"] = $date[0];
# Universal
$Return["time"] = $date[1];
$Return["unix_datetime"] = strtotime($Return["datetime"]["us"]);
$Return["unix_date"] = strtotime($Return["date"]["us"]);
$Return["getdate"] = getdate($Return["unix_datetime"]);
# BR
$Return["datetime"]["br"] = date("d/m/Y H:i:s", $Return["unix_datetime"]);
$Return["date"]["br"] = date("d/m/Y", $Return["unix_date"]);
# Return
return $Return;
} # End Function
Solution 9 - Php
You can try the strftime()
function. Simple example: strftime($time, '%d %m %Y');
Solution 10 - Php
Use this function to convert from any format to any format
function reformatDate($date, $from_format = 'd/m/Y', $to_format = 'Y-m-d') {
$date_aux = date_create_from_format($from_format, $date);
return date_format($date_aux,$to_format);
}
Solution 11 - Php
Given below is PHP code to generate tomorrow's date using mktime()
and change its format to dd/mm/yyyy format and then print it using echo
.
$tomorrow = mktime(0, 0, 0, date("m"), date("d") + 1, date("Y"));
echo date("d", $tomorrow) . "/" . date("m", $tomorrow). "/" . date("Y", $tomorrow);
Solution 12 - Php
date('m/d/Y h:i:s a',strtotime($val['EventDateTime']));
Solution 13 - Php
In PHP any date can be converted into the required date format using different scenarios for example to change any date format into Day, Date Month Year
$newdate = date("D, d M Y", strtotime($date));
It will show date in the following very well format

Solution 14 - Php
For this specific conversion we can also use a format string.
$new = vsprintf('%3$s-%2$s-%1$s', explode('-', $old));
Obviously this won't work for many other date format conversions, but since we're just rearranging substrings in this case, this is another possible way to do it.
Solution 15 - Php
Simple way Use strtotime()
and date()
:
$original_dateTime = "2019-05-11 17:02:07"; #This may be database datetime
$newDate = date("d-m-Y", strtotime($original_dateTime));
With time
$newDate = date("d-m-Y h:i:s a", strtotime($original_dateTime));
Solution 16 - Php
You can change the format using the date() and the strtotime().
$date = '9/18/2019';
echo date('d-m-y',strtotime($date));
Result:
18-09-19
We can change the format by changing the ( d-m-y ).
Solution 17 - Php
Use date_create
and date_format
Try this.
function formatDate($input, $output){
$inputdate = date_create($input);
$output = date_format($inputdate, $output);
return $output;
}
Solution 18 - Php
function dateFormat($date)
{
$m = preg_replace('/[^0-9]/', '', $date);
if (preg_match_all('/\d{2}+/', $m, $r)) {
$r = reset($r);
if (count($r) == 4) {
if ($r[2] <= 12 && $r[3] <= 31) return "$r[0]$r[1]-$r[2]-$r[3]"; // Y-m-d
if ($r[0] <= 31 && $r[1] != 0 && $r[1] <= 12) return "$r[2]$r[3]-$r[1]-$r[0]"; // d-m-Y
if ($r[0] <= 12 && $r[1] <= 31) return "$r[2]$r[3]-$r[0]-$r[1]"; // m-d-Y
if ($r[2] <= 31 && $r[3] <= 12) return "$r[0]$r[1]-$r[3]-$r[2]"; //Y-m-d
}
$y = $r[2] >= 0 && $r[2] <= date('y') ? date('y') . $r[2] : (date('y') - 1) . $r[2];
if ($r[0] <= 31 && $r[1] != 0 && $r[1] <= 12) return "$y-$r[1]-$r[0]"; // d-m-y
}
}
var_dump(dateFormat('31/01/00')); // return 2000-01-31
var_dump(dateFormat('31/01/2000')); // return 2000-01-31
var_dump(dateFormat('01-31-2000')); // return 2000-01-31
var_dump(dateFormat('2000-31-01')); // return 2000-01-31
var_dump(dateFormat('20003101')); // return 2000-01-31
