PHP - Timestamp Vs Timezones

Hi,

I have in my DB a column with a timestamp as definition.
Now I would like to have only the month and year of that column for further use in a form.

How can I achieve that?

Thanks!

   I have this date in database I must convert it to Unix Timestamp How ?      
   2010-11-11 09:04:44
   
   I try this
   echo mktime($mydate);
   
   but its not work its return wrong Timestamp becase if I convert back it I have wrong date 2011-02-16 21:01:33

How do i correctly update a timestamp?
Code: [Select]
$date = date("Y-m-d H:i:s");

mysql_query("UPDATE mmembers set time=now() where email=$myusername");

What is the proper way to turn a date that is in "m/d/Y" format, into a correct timestamp. When I try strtotime, then try to change it back to a date, it shows up incorrectly (defaulting to the 1969 date that it does
when it messes up.

I just need to be able to turn

$date = '10/15/2011'; to and from a timestamp correctly. Any advice?

Hey there,

Thanks for taking the time to read my thread. I've encountered a problem that I cannot figure out a way to solve. I need to calculate the remaining days until a specified unix timestamp. I haven't yet figured out how to get the amount of days until the timestamp.


If anybody could tell me how to get the remaining days until a unix timestamp I would be grateful, thanks.

I have a update query that should be updating the timestamp when a "month" field is changed.    I have the following code:   $month_update->bindParam(':timestamp', strtotime (date("Y-m-d H:i:s")), PDO::PARAM_INT);   The result that is returned is 1403198033.  I need it to look like this 2014-03-26 07:09:06.    I know I am missing something and I would greatly appreciate your help.   Thank you so much!  

$epocTime = $math.newInt($math.divide("$today.getTime()", "1000")))

I need to set two variables for use within my pages, one containing a date as a string in format 'YYYY-MM-DD HH-MM-SS' and another containing the same date as a timestamp.

The date and time stored will take on the value passed in the url if available, else will be for the current date.  The time should always be midnight at the beginning of the date.

eg.  $datestr = '2010-09-08 00:00:00'  and  $datestamp = '1283904000'

Where a date is passed in the url, it will be in the format 'YYYY-MM-DD'.

The problem I am having is getting an accurate timestamp.  I think the trouble is connected to the handling of daylight saving time as it it always an hour out.  What I have at the present is as below:

Code: [Select]
<?php
// ensure all date and time functions are relative to the correct timezone (UK)
date_default_timezone_set('Europe/London');

// string holding selected / current date in format 'YYYY-MM-DD HH:MM:SS'
$datestr = (isset($_GET['date']) ? $_GET['date']." 00:00:00" : gmdate("Y-m-d")." 00:00:00");

// int holding selected / current date as unix timestamp
$datestamp = strtotime($datestr);
?>

Can anybody give me a simple way of converting $datestr into $datestamp to ensure that this is always correct for my UK timezone, irrespective of whether we are in or out of daylight saving time?

Hey there,

Thanks for taking the time to read my thread.

My issue is if I'm given a time stamp in PHP how could I calculate the number of days until that time stamp?.

Thanks for your time.

I have a timestamp field in my mySQL table and need to check if it's 14 day or older.  What's the best way to do this?

Any help will be appreciated

Hello!
I'm trying to develop some kind of RSS news aggregator and I want to show only feeds younger than 1day. I figured i could transform RSS pubDate to timestamp (strtotime()), but there are some feeds without timestamp (like: http://izklop.com/xmldata/rsslinks.xml). Is there any other way to do it, so I could find timestamp from those feeds without pubdate?

If there isn't any other way, do You think it is ok, to just show last 5 feeds?

I hope I made my self clear, and please forgive me for my English

Hi.

I have this code which input data to the database.
Code: [Select]
<?php


include("connect.php");

echo $date = date("Y-m-d H:i:s");
echo "\n <br />";

echo $date2 = date('Y-m-d H:i:s', strtotime("+20 seconds")); 
mysql_query("UPDATE users2 SET date2 = '$date2'");


$query = mysql_query("SELECT date2 FROM users2");
$numrows = mysql_num_rows($query);

if ($numrows != 0)
{
while ($row = $mysql_fetch_array($query))
{
$date_final = $row['date2'];
}
}
echo $date_final;
?>
Variable date2 is stored as timestamp. Now i want to display this two variable on the web, but this code doesn't work. Why? Thank you.

I've been looking at converting my php timestamps to display as month, day, and the hour and minute the event occurred on, i tried;

Code: [Select]
$time = date("j/n H:i", $Events['timestamp']);
But no success can anyone point me in the correct direction? Thanks

How would I go about adding a timestamp to my image uploads so I don't erase image files with the same name? Also, what would be the correct use of the mysql_escape_string

<?php

require_once('storescripts/connect.php');
mysql_select_db($database_phpimage,$phpimage);
$uploadDir = 'upload/';
if(isset($_POST['upload' . $config]))
{
foreach ($_FILES as $file)
{
$fileName = $file['name'];
$tmpName = $file['tmp_name'];
$fileSize = $file['size'];
$fileType = $file['type'];

if($fileName==""){

$filePath = 'upload/';
}
else{

$filePath = $uploadDir . $fileName;
}

$filePath = str_replace(" ", "_", $filePath);
$result = move_uploaded_file($tmpName, $filePath);

if(!get_magic_quotes_gpc())
{
$fileName = addslashes($fileName);
$filePath = addslashes($filePath);
}
$fileinsert[]=$filePath;
}
}

$mid   = mysql_real_escape_string(trim($_POST['mid']));
$cat   = mysql_real_escape_string(trim($_POST['cat']));
$item  = mysql_real_escape_string(trim($_POST['item']));
$price = mysql_real_escape_string(trim($_POST['price']));
$about = mysql_real_escape_string(trim($_POST['about']));

$fields = array();
$values = array();
$updateVals = array();
for($i=1; $i<=4; $i++)
{
    $fields[$i] = 'name'.$i;
    $values[$i] = mysql_real_escape_string(basename(trim($_FILES[$fields[$i]]['name'])));
    if($values[$i] != '')
    {
        $updateVals[] = "{$fields[$i]} = '{$values[$i]}'";
    }
}

$updateNames = '';
if(count($updateVals))
{
    $updateNames = ", " . implode(', ', $updateVals);
}

$update = "INSERT INTO image
               (mid, cid, item, price, about, name1, name2, name3, name4)
           VALUES
               ('$mid', '$cat', '$item', '$price', '$about', '$values[1]', '$values[2]', '$values[3]', '$values[4]')
           ON DUPLICATE KEY UPDATE
                cid = '$cat', item = '$item', price = '$price', about = '$about' $updateNames";
$result = mysql_query($update) or die (mysql_error());

$id = mysql_insert_id();
