UNIX Mktime To MySQL Date Or Date

A form that sends a starting date and an ending date. I have figured out how to tell the difference between the two and even rip the difference into an array because I need to compare the individual dates against a mySQL database to pull results from a particular date in a series. This is no problem. My problem is that teh mySQL database uses DATE as a field definition and this can not be changed. I managed to pull the date differences using some cleaver mktime stuff but no I do not know how to get this 1072242000 into this 2003-12-24...

Is there a function that reverses the mktime result into a usable date format? I would take anything at this point and I can explode and then array it to get what I want - but there has to be something. Code:

Mktime() And Date()

My users submit the date in format mm/dd/yyy via post, and I then want to display in a particular format using the date() and mktime() functions.

//format class dates
$classdate[0] = $_POST['classyear'];
$classdate[1] = $_POST['classmonth'];
$classdate[2] = $_POST['classday'];
$classdate = implode("-",$classdate);
$classdateDisplay= date('F d, Y', mktime(0,0,0,$classdate[1],$classdate[2],$classdate[0]));

echo "debug: $classdate = $classdate<br />";
echo "debug: $classdateDisplay = $classdateDisplay<br />";

When I enter the values 2008/01/01 in the form, $classdate then correctly is displayed as 2008-01-01.

But when I echo $classdateDisplay, it displays "December 3, 2001."

I'm following the formatting as described http://us.php.net/mktime (here), which is:

int mktime ( [int $hour [, int $minute [, int $second [, int $month [, int $day [, int $year [, int $is_dst]]]]]]] )

What am I missing here?

Date And Mktime()

I am having a prob inserting a timestamp into database. My form passes a manually entered date in this format dd-mm-yy (eg 01-02-06). I then use this code to seperate the date, month and year; PHP Code:

$date = explode("-", $date);
$date = mktime(0,0,0,$date[1],$date[0],$date[2]);

Problem is that the timestamp doesnt seem to change, no matter what date i input, it stores in the database as 8388607.

Date Conversions ( Date, Mktime )

I have a date in three pieces dd mm yyyy.
I'm just wondering the best way to convert this for inserting into a
DATETIME field and then back again when displaying it.

I have tried date, strtotime mktime but it keeps inserting a blank
date. i.e. 00:00:00 00:00...

I've been looking through the php manual but I can't seem to get this
working.
Also would I be better off using the UNIX_TIMESTAMP function?

Problem With Date() And Mktime()

I have a php mailing list script written by someone i can't remember but its a good script so thanks. The problem is that when I send mail out it does not reach aol or lycos users. Is this because they see this as spamming?

I changed the from bit to a valid email address but it still doesnt work. Does the mail function need any extra parameters to show its not spam if that is the problem.

Compare Two Date Using Mktime?

I have a string that is submitted via a form and need to check to see if it is within a date range (10/04/09 - 05/06/09). String format is d/m/y. Ive been playing around with the code below but have had no luck. Im not new to php but Ive had next to no experience with date functions. I have also tried using strtotime() but it changes the d/m order around.

$date1 = date("d/m/y", mktime(0, 0, 0, 04, 10, 2009));
$date2 = date("d/m/y", mktime(0, 0, 0, 06, 05, 2009));
$date3 = $_POST['date'];
$parts = explode('/', $date3);

Date() And Mktime() Output Mar Instead Of Feb

I'm getting a wierd result using the date function along with mktime. here's my code: echo date('M', mktime(0,0,0,2));Looks simple enough.. For some reason though it outputs 'Mar', but march is the third month. If I switch the 2 with 3 it outputs 'Mar'. All the other months come out correctly, just feb comes out as 'Mar' and I can't figure it out...

Date Manipulation - Mktime

I have created 2 pages to query a database. There are 2 bits of date manipulation with which I am having a problem:

Last Week and Last Month - when the user clicks Last week, I need a string produced. If today is 05/05/2007, the string I need produced is "29/04/2007...04/05/2007" which is the last 7 days.

If the user clicks Last Month, I need just the number produced, so if this month is May, I need 4 produced. I have tried all sorts of stuff with mktime, but it just produces rubbish, here is an example of my code:

Date Calculation Problem W/ Mktime()

I am having a problem with calculating a date. What I am looking to do
is get the date of Sunday of this week, then use mktime() to find out
other days in the past by subtracting days.

In the code below, today is Saturday, October 16, 2004, this week's
Sunday is 2004-10-17. I successfully get that.

But, when I try to subtract 7 days using mktime(), I instead of getting
2004-10-10, I get 1969-12-31.

I have looked through php.net/mktime and searched some example via
Google, but I stuck. Any help would be greatly appreciated.

CODE BELOW:

$today = unixtojd();

// GET THIS WEEK'S SUNDAY
$this_sunday = $today + (7 - jddayofweek($today)) % 7;
$current_sunday = jdtogregorian($this_sunday);
$this_sundays_parts = explode("/",$current_sunday);
$cur_sunday = $this_sundays_parts[2] . "-" . $this_sundays_parts[0] .
"-" . $this_sundays_parts[1];

// GET LAST WEEK'S SUNDAY

$last_sunday = date("Y-m-d", mktime(0, 0, 0,
date($this_sundays_parts[2]), date($this_sundays_parts[0]),
date($this_sundays_parts[1])-7));

// PRINT OUT THE DATES
print "This Sunday is " . $cur_sunday . "<BR>";
print "Last Sunday was " . $last_sunday . "<BR>";

Is Mktime() Using Date() Daylight Saving Aware?

I've read through a few questions about this here on s.o. and none seem to ask or answer the question very bluntly: $ts_today = mktime( 0, 0, 0, date('m'), date('d'), date('Y') ); is this daylight saving aware? if not, how do i make mktime() daylight saving aware?

Pass The Contents From $row[date] Into The Mktime() Function?

New user of PHP here! I'm using it to display entries from my MYSQL database. Image below.

This is the code snippet that displays information from the 'name', 'author' and 'date' columns of my database. I learned this technique from w3schools.

$result = mysql_query("SELECT * FROM levels ORDER BY date DESC");

while($row = mysql_fetch_array($result))
{
echo "<tr>";
echo "<td>" . $row['name'] . "</td>";
echo "<td>" . $row['author'] . "</td>";
echo "<td align='right'>" . $row['date'] . "</td>";
echo "</tr>";
}

I would like to use the date() function to format the date differently. But the date() function requires that I convert my time into a timestamp. I know you have to use the mktime() function for this, but I don't know how. how to pass the contents from $row[date] into the mktime() function?

Arbitrary Mktime - Doesn't Allow Negative Date Values

I'm prefacing this post by saying that I already know that the unix epoch is 1970 to 2038 and that Windows doesn't allow negative date values. Just so that isn't regurgitated as an answer and I waste more time on this issue. I have a function that takes a user's birthdate and validates it by which I mean it makes sure that they aren't born before 1900 and are at least 18 years old.

function mkBDay($month, $day, $year) {
$month = str_pad($month, 2, "00", STR_PAD_LEFT);
$day = str_pad($day, 2, "00", STR_PAD_LEFT);
if($year <= 10) {
$year = str_pad($year, 4, "2000", STR_PAD_LEFT);
} else {
$year = str_pad($year, 4, "1900", STR_PAD_LEFT);
}
[Code]....

I've assigned a variable to the mktime call at the end and dumped it during a little testing. What I've seen is that if the year is before 1970 and before 1902 the value is negative. Fine. However if the year is 1900 or 1901 it's false. The inconsistency doesn't make any sense to me and seems arbitrary. Is there a reason that it doesn't like either of those years? Or maybe I wrote my function incorrectly.

Mktime With A Date Less Than The Year 1969 I Get A Negative Integer?

When I do mktime with a date less than the year 1969 I get a negative integer. That is fine however because when I used date it would get the correct time for say a date in the year 1945. But I just noticed when I do say year 1900 it will just use 0.
