Unable to store date and timestamp values in mysql - php

I have date and timestamp fields in mysql table.
$timeString="Thu Jul 26 22:45:09 +0000 2012";
$time=strtotime($timeString);
$date=date('Y-m-d', $timeString);
When I execute the query it storing the following values:
date 0000-00-00
time 0000-00-00 00:00:00
Can anyone fix my problem.

you're trying to build your date from $timestring (the string) instead of $time(the timestamp )
try:
$timeString="Thu Jul 26 22:45:09 +0000 2012";
$time=strtotime($timeString);
$date=date('Y-m-d', $time);
you should enable php warnings in your development environment.
date would have told you :)
date() expects parameter 2 to be long, string given

$date = new DateTime('Thu Jul 26 22:45:09 +0000 2012');
echo $date->format('Y-m-d H:i:s');

Display reformatted date from MySQL in PHP

I have a field within a MySQL database that has a date format of the following:
Mon, 17 Aug 2015 19:14:22 +0100
I want to display this date using PHP in the following format:
YYYY-MM-DD HH:MM:SS
I have no idea how to pick out the different elements and reformat them.
Can somebody help?
Many thanks,
John
You can try these :-
$date = "Mon, 17 Aug 2015 19:14:22 +0100";
$newDate = date('Y-m-d H:i:s', strtotime($date));
echo $newDate;
You can do it in mysql
SELECT
DATE_FORMAT(test.dateFrom, '%Y-%M-%d %H:%i:%s') as date,
FROM test
Or in php
$date = date('Y-m-d H:i:s', strtotime($datefrommysql) );

What create_from_format to use for timestamps in php

I am working on a PHP file were I am pulling in timestamps from a database that come out as
Tue Sep 22 16:11:12 EDT 2015
Mon Nov 16 07:42:31 EST 2015
I was wondering how to convert dates of this format into unix time format.
You can use the DateTime object
$dateTime = new DateTime('Tue Sep 22 16:11:12 EDT 2015');
echo $dateTime->getTimestamp();
The result would be 1442952672
If you look at the PHP manual for \DateTime::createFromFormat() or date(), you will find tables of codes accepted by \DateTime::createFromFormat(). Looking at them you will see that you need the following:-
$date = \DateTime::createFromFormat('D M d H:i:s T Y', 'Tue Sep 22 16:11:12 EDT 2015');
echo $date->getTimestamp();
Demo.
The 'd' in the format string may need to be a 'j' if day numbers < 10 are single digit.

Converting Date format in PHP

I am getting a date format like Mon Apr 22 2013 12:16:00 GMT+0530 (India Standard Time) form a javascript to my php function.
I want to store that to my database table in "2013-04-22 12:16:00" format.
Can any one help me to convert this date type.
I tried:
date("Y-m-d H:i:s",$startDate);
But it's giving error as
date() expects parameter 2 to be long string given
Use strtotime() and date():
$originalDate = "Mon Apr 22 2013 12:16:00 GMT+0530 (India Standard Time)" ;
$newDate = date("Y-m-d H:i:s", strtotime($originalDate));
(see strtotime and date docs on the PHP site).
or use DateTime:
<?php
$source = "Mon Apr 22 2013 12:16:00 GMT+0530 (India Standard Time)";
$date = new DateTime($source);
echo $date->format("Y-m-d H:i:s"); // 22 2013 12:16:00
echo $date->format("Y-m-d H:i:s"); // 22 2013 12:16:00
?>
DEMO
Try using strtotime to convert the timestamp to unix-format so you can use it in the date() function:
date("Y-m-d H:i:s",strtotime($startDate));
You can also try using the (usually included) DateTime class. In particular, have a look at DateTime::createFromFormat. It may help you get around ambiguities in the date string (strtotime() will sometimes fail or mis-parse a date string). DateTime::createFromFormat allows you to specifically designate the format of the date string so there can be no ambiguity.
firstly you need to save it as Timestamp so,
$startDate = strtotime($javascript_value);
$result = date("Y-m-d H:i:s",$startDate);

Linux timestamp to PHP

I have the following timestamp:
1342259667654
which when converted with http://www.epochconverter.com/ gives:
Assuming that this timestamp is in milliseconds:
GMT: Sat, 14 Jul 2012 09:54:27 GMT
Your time zone: 14. juli 2012 11:54:27 GMT+2
And that is the correct time, but when using:
echo date("Y-m-d H:i:s", 1342259667654);
I get the following date:
1904-07-24 10:22:47
How can I get with PHP the exact date out of this time stamp?
Your timestamp needs to be divided by 1000:
echo date("Y-m-d H:i:s", 1342259667654/1000);
$timestamp = 1342259667;
$dt = new DateTime("#$timestamp"); // convert UNIX timestamp to PHP DateTime
echo $dt->format('Y-m-d H:i:s');
You can also do it this way.
The value 1342259667654 is actually in miliseconds, while PHP's date() function is unable to handle miliseconds value. Hence the weird output.

convert any date string to timestamp without timezone

I'm getting xml and rss feeds and putting the data into a database. I've run into two different date formats so far...
Wed, 21 Jul 2010 00:28:50 GMT
And
2010-07-20T17:33:19Z
I'm sure there will be more. My postgresql database for the date is timestamp without time zone. Is there an existing function in php or is there a procedure to convert the any date strings to timestamp without time zone (Y-m-d H:i:s)?
Use date with strtotime:
$date = date('Y-m-d H:i:s', strtotime('Wed, 21 Jul 2010 00:28:50 GMT'));
echo $date;
Result:
2010-07-21 05:28:50
.
$date = date('Y-m-d H:i:s', strtotime('2010-07-20T17:33:19Z'));
echo $date;
Result:
2010-07-20 22:33:19
You don't need to convert it at all. PostgreSQL should convert automatically:
postgres=# create table test_tz (f1 timestamp without time zone);
CREATE TABLE
postgres=# insert into test_tz (f1) values ('Wed, 21 Jul 2010 00:28:50 GMT');
INSERT 0 1
postgres=# insert into test_tz (f1) values ('2010-07-20T17:33:19Z');
INSERT 0 1
postgres=# select f1 from test_tz;
f1
---------------------
2010-07-21 00:28:50
2010-07-20 17:33:19
Timestamps are considered to be UTC.
$dt = new DateTime('Wed, 21 Jul 2010 00:28:50 GMT');
echo $dt->format('U'); // 1279672130
is the same timestamp as
$dt = new DateTime('Wed, 21 Jul 2010 02:28:50 CEST');
echo $dt->format('U'); // 1279672130
Note that the U formatting option requires PHP5.3 though. When supplying a timezone identifier in the Date String, the DateTime object recognizes the Timezone, so when you call the following on the GMT DateTime instance
echo $dt->format('Y-m-d H:i:s');
it will return 2010-07-21 00:28:50. You can change a DateTime object's timezone with it's setTimezone() method though.
$dt = new DateTime('Wed, 21 Jul 2010 02:28:50 GMT+2');
$dt->setTimezone(new DateTimeZone('UTC'));
echo $dt->format('Y-m-d H:i:s'); // 2010-07-21 00:28:50
But if you just need the timestamp, it's not needed.
