PHP: Convert from MySQL timestamp (yyyymmddhhiiss) to date

In a database, signup times are stored as a timestamp field, which means the date is stored as follows:

20110307120000

I need to be able to display these using PHPs date function - is there an easy way to do this?

strtotime on this value just gives the value for 01/01/1970...

Thanks

$date_format=date("m:d:y",$time_stamp); // formats timestamp in mm:dd:yy  
 
print $date_format; // results here ... 02 : 11 : 07

Hi,
inside PHP you can convert simply with date() function:
$date_format=date("m:d:y",$time_stamp); // formats timestamp in mm:dd:yy

Open in new window

or inside MySQL, for example:
# $select = array();
# $select[] = "MONTH(timeStamp) AS theMonth";
# $select[] = "DAY(timeStamp) AS theDay";

...then print it out with PHP:
<?php
echo $results["theMonth"]."/".$results["theDay"];
?>

Open in new window

The rest you can fing in PHP docs under date() function or in MySQL docs under TIME or TIMESTAMP

Hi - sorry, but omitting strtotime just moves the problem to the other end of the spectrum and results in 19-01-2038 as the output date regardless of what time is entered.

ie.

$timestamp = "20110307121543";
echo date("d-m-Y", $timestamp);

(the other route, which gives 01-01-1970 was:

$timestamp = "20110307121543";
echo date("d-m-Y", strtotime($timestamp));

)

What I need, is 07-03-2011

try this
$date = "20110307121543";

echo sprintf("%02s:%02s:%02s", substr($date,4,2),substr($date,6,2),substr($date,2,2));

try this

for your output 07-03-2011
$date = "20110307121543";

echo sprintf("%02s-%02s-%02s", substr($date,6,2),substr($date,4,2),substr($date,0,4));

Hi,

That gives me the print out, but I'm actually passing this to another date function to give me the date in long form (March 7th, 2011) - is there a way of getting that output as a string so I can then pass it to date()?

Thanks

For clarification, the timestamp is the number of seconds since the beginning of the epoch. The value you have 20110307120000, is the date and time stored as a string in year month day format ie.

2011/03/07:12:00:00

you use date_parse() to get this.

print_r(date_parse("20110307120000"));

I'm aware that the UNIX timestamp is seconds since the beginning of the epoch - however the value provided is the value that gets stored in my MySQL timestamp field - does that mean my hosts have the server setup wrong?

Tried using 'date_parse' but am getting an undefined function error?

<?
$timestamp = "20110307121543";
echo date_parse($timestamp);
?>

OK -  so tweaking pratima_mcs's offering seems to do the trick:

$timestamp = "20110307121543";
$newdate = sprintf("%02s-%02s-%02s", substr($timestamp,0,4),substr($timestamp,4,2),substr($timestamp,6,2));
echo date('F d, Y', strtotime($newdate));

Open in new window

just use this for date and time.

$date_time = (string)20110307120000;
$year = substr($date_time, 0, 4);
$month = substr($date_time, 4, 2);
$date = substr($date_time, 6, 2);
$hour = substr($date_time, 8, 2);
$minute = substr($date_time, 10, 2);
$second = substr($date_time, 12, 2);

$timestamp = mktime($hour, $minute, $second, $month, $date, $year);
echo date('Y-m-d H:i:s', $timestamp);
