PHP date not parsed probably [duplicate] - php

Convert one date format into another in PHP
(17 answers)
Closed 1 year ago.
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?

Answer 1

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 :-)

Answer 2

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
?>

Answer 3

Use:
implode('-', array_reverse(explode('-', $date)));
Without the date conversion overhead, I am not sure it'll matter much.

Answer 4

$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.

Answer 5

$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));

Answer 6

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 :)

Answer 7

There are two ways to implement this:
1.
$date = strtotime(date);
$new_date = date('d-m-Y', $date);
2.
$cls_date = new DateTime($date);
echo $cls_date->format('d-m-Y');

Answer 8

Note: Because this post's answer sometimes gets upvoted, I came back
here to kindly ask people not to upvote it anymore. My answer is
ancient, not technically correct, and there are several better
approaches right here. I'm only keeping it here for historical
purposes.
Although the documentation poorly describes the strtotime function,
#rjmunro correctly addressed the issue in his comment: it's in ISO
format date "YYYY-MM-DD".
Also, even though my Date_Converter function might still work, I'd
like to warn that there may be imprecise statements below, so please
do disregard them.
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

Answer 9

You can try the strftime() function. Simple example: strftime($time, '%d %m %Y');

Answer 10

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);

Answer 11

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);
}

Answer 12

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

Answer 13

date('m/d/Y h:i:s a',strtotime($val['EventDateTime']));

Answer 14

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

Answer 15

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.

Answer 16

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));

Answer 17

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 ).

Answer 18

Use date_create and date_format
Try this.
function formatDate($input, $output){
$inputdate = date_create($input);
$output = date_format($inputdate, $output);
return $output;
}
