Date conversion with different gmt

Date conversion with different gmt - php

I have two dates in my database
This date is from an api - 16 Nov 2017 10:54:12 +0000
This date is from my server - 16 Nov 2017 16:24:12 +0530
I want to convert this date into 16 Nov 2017 10:54:12 +0000 in my server time.

$value = "16 Nov 2017 10:54:12 +0000";
echo date(DATE_RFC822, strtotime($value));

How to calculate number of mondays in a given month? [duplicate]

I need to output a list of dates (only Mondays and Tuesdays) for the next 12 months from current date like so:
Jan 2010
Tue 12 Jan 2010
Mon 18 Jan 2010
Tue 19 Jan 2010
Mon 25 Jan 2010
Feb 2010
Tue 02 Feb 2010
Mon 08 Feb 2010
Tue 09 Feb 2010
Mon 15 Feb 2010
Tue 16 Feb 2010
Mon 22 Feb 2010
Mar 2010
Tue 09 Mar 2010
Mon 15 Mar 2010
Tue 16 Mar 2010
...
Being new to PHP I figured strtotime and looping over the next 52 weeks is the best way to go.
$blockedDatesInput = "08 Mar 2010,12 Apr 2010"; // dont show these dates
$blockedDates = explode ("," , $blockedDatesInput); // convert to array
$currentMonth = ""; // current month marker
// loop over the next 52 weeks to find Mondays and Tuesdays
for($i=0; $i<=52; $i++){
// build the month header
$monthReference = date("M Y", strtotime('+'.$i.' Week'));
// check if date exists in $blockeddate
if (!in_array(date("d M Y", strtotime('+'.$i.' Monday')), $blockedDates) ||
!in_array(date("d M Y", strtotime('+'.$i.' Tuesday')), $blockedDates) ) {
// check if we have to show a new month
if(strcmp($monthReference, $currentMonth) <> 0){
echo $monthReference.'<br />',"\n";
}else{
// output the dates
echo date("D d M Y", strtotime('+'.$i.' Monday')).'<br />',"\n";
echo date("D d M Y", strtotime('+'.$i.' Tuesday')).'<br />',"\n";
}
$currentMonth = date("M Y", strtotime('+'.$i.' Week'));
}
}
However the output from my code is
Jan 2010
Mon 18 Jan 2010

As you can see the dates are not in the right order and I am at a loss where I am going wrong here.
Is there a more elegant / simple way to solve this?
Version of PHP used is 5.2.11 and no prospect of going to 5.3 anytime soon :-(
Thanks for your help.
Code below modification as suggested by Aly.
Changed the computer date from Tue, 12/01/2010 to Wed, 13/01/2010 to test the output.
$blockedDatesInput = "08 Mar 2010,12 Apr 2010"; // dont show these dates
$blockedDates = explode ("," , $blockedDatesInput); // convert to array
$currentMonth = ""; // current month marker
// loop over the next 52 weeks to find Mondays and Tuesdays
for($i=0; $i<=52; $i++){
// build the month header
$monthReference = date("M Y", strtotime('+'.$i.' Week'));
// check if date exists in $blockeddate
if (!in_array(date("d M Y", strtotime('+'.$i.' Monday')), $blockedDates) ||
!in_array(date("d M Y", strtotime('+'.$i.' Tuesday')), $blockedDates) ) {
// check if we have to show a new month
if(strcmp($monthReference, $currentMonth) <> 0){
echo $monthReference.'<br />',"\n";
}else{
// output the dates (changed the order as suggested by Aly)
echo date("D d M Y", strtotime('+'.$i.' Tuesday')).'<br />',"\n";
echo date("D d M Y", strtotime('+'.$i.' Monday')).'<br />',"\n";
}
$currentMonth = date("M Y", strtotime('+'.$i.' Week'));
}
}
Output again in the wrong order.

This is an interesting one. Here's how I'd do it with functions, though it may warrant its own class to really be modular and reusable:
Set up my date formats and excluded dates
define('INTERNAL_FORMAT', 'Y-m-d');
define('DISPLAY_MONTH_FORMAT', 'M Y');
define('DISPLAY_DAY_FORMAT', 'D d M Y');
// format excluded dates as YYYY-MM-DD, date('Y-m-d'):
$excluded_dates = array(
'2010-03-09',
'2010-04-13',
);
Then I need some utility functions to see how the dates run, and what dates are excluded:
// date('w') returns a string numeral as follows:
// '0' Sunday
// '1' Monday
// '2' Tuesday
// '3' Wednesday
// '4' Thursday
// '5' Friday
// '6' Saturday
function isTuesday($date) {
return date('w', strtotime($date)) === '2';
}
function isWednesday($date) {
return date('w', strtotime($date)) === '3';
}
// handle the excluded dates
function isExcludedDate($internal_date) {
global $excluded_dates;
return in_array($internal_date, $excluded_dates);
}
Now we just need to iterate over every day of the next 365 (the next year) and check to see if they're Tuesday or Wednesday and not on the excluded list. We store this in $months_and_dates:
$start_date = date(INTERNAL_FORMAT);
// something to store months and days
$months_and_dates = array();
// loop over 365 days and look for tuesdays or wednesdays not in the excluded list
foreach(range(0,365) as $day) {
$internal_date = date(INTERNAL_FORMAT, strtotime("{$start_date} + {$day} days"));
$this_day = date(DISPLAY_DAY_FORMAT, strtotime($internal_date));
$this_month = date(DISPLAY_MONTH_FORMAT, strtotime($internal_date));
if ((isTuesday($internal_date) || isWednesday($internal_date))
&& !isExcludedDate($internal_date)) {
$months_and_dates[$this_month][] = $this_day;
}
}
You can print_r() it, or to get the display you want, we do this:
foreach($months_and_dates as $month => $days) {
print $month . "<br>";
print implode('<br>', $days);
print "<br>";
}
Here's the result as of today, January 11, 2010:

in a funny coincidence, because today is monday, it is skipping one monday value, that's why they appear out of order. yesterday it would have worked fine.
i.e. your "+ 0 Monday" is NEXT monday, not today.
you may want to look into the "N" format character for date().

Ok now that your computers date is Wednesday you want to print the Mondays before the Tuesdays as the next Monday is closer to Wednesday than the next Tuesday. So try this:
$blockedDatesInput = "08 Mar 2010,12 Apr 2010"; // dont show these dates
$blockedDates = explode ("," , $blockedDatesInput); // convert to array
$currentMonth = ""; // current month marker
// loop over the next 52 weeks to find Mondays and Tuesdays
for($i=0; $i<=52; $i++){
// build the month header
$monthReference = date("M Y", strtotime('+'.$i.' Week'));
// check if date exists in $blockeddate
if (!in_array(date("d M Y", strtotime('+'.$i.' Monday')), $blockedDates) ||
!in_array(date("d M Y", strtotime('+'.$i.' Tuesday')), $blockedDates) ) {
// check if we have to show a new month
if(strcmp($monthReference, $currentMonth) <> 0){
echo $monthReference.'<br />',"\n";
}else{
// output the dates (changed the order as suggested by Aly)
echo date("D d M Y", strtotime('+'.$i.' Monday')).'<br />',"\n";
echo date("D d M Y", strtotime('+'.$i.' Tuesday')).'<br />',"\n";
}
$currentMonth = date("M Y", strtotime('+'.$i.' Week'));
}
}

<?php
/*
#$listDaysOfWeek list days
0 = Monday
1 = Tuesday
2 = Wednesday
3 = Thursday
4 = Friday
5 = Saturday
6 = Sunday
*/
function DatesFromDaysOnWeek(\Datetime $objDateTime, int $numAddDays , array $listDaysOfWeek)
{
$listDaysOfWeek = array_intersect($listDaysOfWeek, range(0,6) );
sort($listDaysOfWeek);
if(empty($listDaysOfWeek) || $numAddDays < 1)
return [];
$results = [];
while ( $numAddDays > 0)
{
foreach($listDaysOfWeek as $numDay)
{
$infoDate = (object) getdate( $objDateTime->getTimestamp() );
if($numDay != $infoDate->wday)
continue;
array_push($results, $objDateTime->format('Y-m-d') );
$numAddDays--;
}
$objDateTime->add(new \DateInterval('P1D'));
}
return $results;
}
#example:
$list = DatesFromDaysOnWeek( (new \DateTime('2019-02-01')) , 4 , [1] );
print_r($list);
$list = DatesFromDaysOnWeek( (new \DateTime('2019-02-01')) , 4 , [2] );
print_r($list);
$list = DatesFromDaysOnWeek( (new \DateTime('2019-02-01')) , 4 , [3] );
print_r($list);
$list = DatesFromDaysOnWeek( (new \DateTime('2019-02-01')) , 4 , [4] );

How can i remove other lines from a csv formatted string using PHP?

Thanks in advance :)

If all you need is to take a string and remove all content after "ROUTING TABLE" then this would work. However it looks like you may want to use it as a CSV after? How are you converting it to a string? Depending on how you are using it you may want to look into converting it into an array from the CSV file and then it would be done slightly different.
<?php
$string = "Lee.leviste,112.198.77.139:44324,12872826,82159116,Thu Dec 15 16:30:18 2016

PHP imap get date from email in epoch time

It's not as easy as strtotime()...
I'm returning dates of emails with php imap. When I return a date, I get this formatting:
21 May 2015 20:48:36 -0400
Fri, 15 May 2015 00:13:12 +0000
Fri, 7 Aug 2015 07:11:42 -0400 (EDT)
Fri, 4 Sep 2015 11:03:15 -0400
Mon, 10 Aug 2015 22:04:10 +0000
Tue, 14 Jul 2015 12:54:47 -0400
Sun, 21 Jun 2015 10:49:06 +0000
Fri, 12 Jun 2015 17:35:26 +0000
Thu, 27 Aug 2015 11:47:55 -0400
Mon, 20 Jul 2015 12:43:45 -0400
Fri, 18 Sep 2015 07:47:04 -0400 (EDT)
etc.
As you can see, the dates aren't exactly consistent. One of the dates does not have a day name (Fri). Some of the dates have an (EDT) tag on it, and the others don't.
I tried using strtotime($date), but I believe that since it has the time zone in some of them, it's messing the date up.
Is there a way to convert these very strange times into epoch time?

You could clean up your input before processing it as time strings:
$input = "21 May 2015 20:48:36 -0400
Fri, 15 May 2015 00:13:12 +0000
Fri, 7 Aug 2015 07:11:42 -0400 (EDT)
Fri, 4 Sep 2015 11:03:15 -0400
Mon, 10 Aug 2015 22:04:10 +0000
Tue, 14 Jul 2015 12:54:47 -0400
Sun, 21 Jun 2015 10:49:06 +0000
Fri, 12 Jun 2015 17:35:26 +0000
Thu, 27 Aug 2015 11:47:55 -0400
Mon, 20 Jul 2015 12:43:45 -0400
Fri, 18 Sep 2015 07:47:04 -0400 (EDT)";
$output = '';
$lines = explode("\n", $input);
foreach($lines as $line) {
$output .= preg_replace('/(\w{3}, )|( \(\w{3}\))/', '', $line)."\n";
}
echo $output;

Issue In fetching for upcoming events

SO I have write the code for getting the list of upcoming events in next 7 days and it is working fine and giving me the list of upcoming events.but the probmlem is that it is also giving the event record of past days also. Here is my code :
$today = strtotime("Now");
echo date('Y-m-d :H:i:s',$today)."<br>";
$leadDate = strtotime("+7 day", $today);
echo date('Y-m-d :H:i:s',$leadDate)."<br>";
$rs = mysql_query("SELECT * FROM names WHERE due_date BETWEEN CURDATE() AND '$leadDate'") or die(mysql_error());
echo "<b>Dues for upcoming 7 days</b><br>";
while($row=mysql_fetch_assoc($rs))
{
echo $row['name']." => ".$row['normal_date']."<br>";

server's today's date is 19 Jan 2014 but it is also giving me the list of 18 Jan 2014 but i am looking for the next 7 days record.and my current script is giving me the following out put:
2014-01-19 :20:44:30
2014-01-26 :20:44:30
Dues for upcoming 7 days
name1 => Mon, 20 Jan 2014 19:14:00 GMT
name2 => Tue, 21 Jan 2014 19:14:00 GMT
name3 => Wed, 22 Jan 2014 19:14:00 GMT
name4 => Fri, 24 Jan 2014 19:14:00 GMT
name9 => Sunday, 19 Jan, 2014
name10 => Saturday, 18 Jan, 2014
name11 => 20 Jan, 2015
So Why the 18 jan 2014 & 20 jan 2014 coming in record, where i am wrong.Please Help.
Thanks in Advance.

Try this code:
$rs = mysql_query("SELECT * FROM names WHERE due_date BETWEEN '$today' AND '$leadDate'") or die(mysql_error());
Instead of the CURDATE function use the $today.

Getting all dates for Mondays and Tuesdays for the next year

Being new to PHP I figured strtotime and looping over the next 52 weeks is the best way to go.
$blockedDatesInput = "08 Mar 2010,12 Apr 2010"; // dont show these dates
$blockedDates = explode ("," , $blockedDatesInput); // convert to array
$currentMonth = ""; // current month marker
// loop over the next 52 weeks to find Mondays and Tuesdays
for($i=0; $i<=52; $i++){
// build the month header
$monthReference = date("M Y", strtotime('+'.$i.' Week'));
// check if date exists in $blockeddate
if (!in_array(date("d M Y", strtotime('+'.$i.' Monday')), $blockedDates) ||
!in_array(date("d M Y", strtotime('+'.$i.' Tuesday')), $blockedDates) ) {
// check if we have to show a new month
if(strcmp($monthReference, $currentMonth) <> 0){
echo $monthReference.'<br />',"\n";
}else{
// output the dates
echo date("D d M Y", strtotime('+'.$i.' Monday')).'<br />',"\n";
echo date("D d M Y", strtotime('+'.$i.' Tuesday')).'<br />',"\n";
}
$currentMonth = date("M Y", strtotime('+'.$i.' Week'));
}
}
However the output from my code is

As you can see the dates are not in the right order and I am at a loss where I am going wrong here.
Is there a more elegant / simple way to solve this?
Version of PHP used is 5.2.11 and no prospect of going to 5.3 anytime soon :-(
Thanks for your help.
Code below modification as suggested by Aly.
Changed the computer date from Tue, 12/01/2010 to Wed, 13/01/2010 to test the output.
$blockedDatesInput = "08 Mar 2010,12 Apr 2010"; // dont show these dates
$blockedDates = explode ("," , $blockedDatesInput); // convert to array
$currentMonth = ""; // current month marker
// loop over the next 52 weeks to find Mondays and Tuesdays
for($i=0; $i<=52; $i++){
// build the month header
$monthReference = date("M Y", strtotime('+'.$i.' Week'));
// check if date exists in $blockeddate
if (!in_array(date("d M Y", strtotime('+'.$i.' Monday')), $blockedDates) ||
!in_array(date("d M Y", strtotime('+'.$i.' Tuesday')), $blockedDates) ) {
// check if we have to show a new month
if(strcmp($monthReference, $currentMonth) <> 0){
echo $monthReference.'<br />',"\n";
}else{
// output the dates (changed the order as suggested by Aly)
echo date("D d M Y", strtotime('+'.$i.' Tuesday')).'<br />',"\n";
echo date("D d M Y", strtotime('+'.$i.' Monday')).'<br />',"\n";
}
$currentMonth = date("M Y", strtotime('+'.$i.' Week'));
}
}
Output again in the wrong order.

This is an interesting one. Here's how I'd do it with functions, though it may warrant its own class to really be modular and reusable:
Set up my date formats and excluded dates
define('INTERNAL_FORMAT', 'Y-m-d');
define('DISPLAY_MONTH_FORMAT', 'M Y');
define('DISPLAY_DAY_FORMAT', 'D d M Y');
// format excluded dates as YYYY-MM-DD, date('Y-m-d'):
$excluded_dates = array(
'2010-03-09',
'2010-04-13',
);
Then I need some utility functions to see how the dates run, and what dates are excluded:
// date('w') returns a string numeral as follows:
// '0' Sunday
// '1' Monday
// '2' Tuesday
// '3' Wednesday
// '4' Thursday
// '5' Friday
// '6' Saturday
function isTuesday($date) {
return date('w', strtotime($date)) === '2';
}
function isWednesday($date) {
return date('w', strtotime($date)) === '3';
}
// handle the excluded dates
function isExcludedDate($internal_date) {
global $excluded_dates;
return in_array($internal_date, $excluded_dates);
}
Now we just need to iterate over every day of the next 365 (the next year) and check to see if they're Tuesday or Wednesday and not on the excluded list. We store this in $months_and_dates:
$start_date = date(INTERNAL_FORMAT);
// something to store months and days
$months_and_dates = array();
// loop over 365 days and look for tuesdays or wednesdays not in the excluded list
foreach(range(0,365) as $day) {
$internal_date = date(INTERNAL_FORMAT, strtotime("{$start_date} + {$day} days"));
$this_day = date(DISPLAY_DAY_FORMAT, strtotime($internal_date));
$this_month = date(DISPLAY_MONTH_FORMAT, strtotime($internal_date));
if ((isTuesday($internal_date) || isWednesday($internal_date))
&& !isExcludedDate($internal_date)) {
$months_and_dates[$this_month][] = $this_day;
}
}
You can print_r() it, or to get the display you want, we do this:
foreach($months_and_dates as $month => $days) {
print $month . "<br>";
print implode('<br>', $days);
print "<br>";
}
Here's the result as of today, January 11, 2010:

in a funny coincidence, because today is monday, it is skipping one monday value, that's why they appear out of order. yesterday it would have worked fine.
i.e. your "+ 0 Monday" is NEXT monday, not today.
you may want to look into the "N" format character for date().

Ok now that your computers date is Wednesday you want to print the Mondays before the Tuesdays as the next Monday is closer to Wednesday than the next Tuesday. So try this:
$blockedDatesInput = "08 Mar 2010,12 Apr 2010"; // dont show these dates
$blockedDates = explode ("," , $blockedDatesInput); // convert to array
$currentMonth = ""; // current month marker
// loop over the next 52 weeks to find Mondays and Tuesdays
for($i=0; $i<=52; $i++){
// build the month header
$monthReference = date("M Y", strtotime('+'.$i.' Week'));
// check if date exists in $blockeddate
if (!in_array(date("d M Y", strtotime('+'.$i.' Monday')), $blockedDates) ||
!in_array(date("d M Y", strtotime('+'.$i.' Tuesday')), $blockedDates) ) {
// check if we have to show a new month
if(strcmp($monthReference, $currentMonth) <> 0){
echo $monthReference.'<br />',"\n";
}else{
// output the dates (changed the order as suggested by Aly)
echo date("D d M Y", strtotime('+'.$i.' Monday')).'<br />',"\n";
echo date("D d M Y", strtotime('+'.$i.' Tuesday')).'<br />',"\n";
}
$currentMonth = date("M Y", strtotime('+'.$i.' Week'));
}
}

<?php
/*
#$listDaysOfWeek list days
0 = Monday
1 = Tuesday
2 = Wednesday
3 = Thursday
4 = Friday
5 = Saturday
6 = Sunday
*/
function DatesFromDaysOnWeek(\Datetime $objDateTime, int $numAddDays , array $listDaysOfWeek)
{
$listDaysOfWeek = array_intersect($listDaysOfWeek, range(0,6) );
sort($listDaysOfWeek);
if(empty($listDaysOfWeek) || $numAddDays < 1)
return [];
$results = [];
while ( $numAddDays > 0)
{
foreach($listDaysOfWeek as $numDay)
{
$infoDate = (object) getdate( $objDateTime->getTimestamp() );
if($numDay != $infoDate->wday)
continue;
array_push($results, $objDateTime->format('Y-m-d') );
$numAddDays--;
}
$objDateTime->add(new \DateInterval('P1D'));
}
return $results;
}
#example:
$list = DatesFromDaysOnWeek( (new \DateTime('2019-02-01')) , 4 , [1] );
print_r($list);
$list = DatesFromDaysOnWeek( (new \DateTime('2019-02-01')) , 4 , [2] );
print_r($list);
$list = DatesFromDaysOnWeek( (new \DateTime('2019-02-01')) , 4 , [3] );
print_r($list);
$list = DatesFromDaysOnWeek( (new \DateTime('2019-02-01')) , 4 , [4] );
print_r($list);
$list = DatesFromDaysOnWeek( (new \DateTime('2019-02-01')) , 4 , [5] );
print_r($list);
$list = DatesFromDaysOnWeek( (new \DateTime('2019-02-01')) , 4 , [6] );
print_r($list);
$list = DatesFromDaysOnWeek( (new \DateTime('2019-02-01')) , 4 , [0] );
print_r($list);
$list = DatesFromDaysOnWeek( (new \DateTime('2019-03-01')) , 100 , [1,2] );
print_r($list);
