RE: [PHP] difference between two times? Date_diff and DateTime::diff
Also, if you're returning data from MySQL, there are a number of operations
you can perform before it reaches your script:

Hi Dajve and Tom,
Thanks again, I totally didn't realise that this function is yet to be
implemented in the mainstream PHP,
So is there no function that exists in vanilla PHP that can take two
dates/times and supply the difference ?
If there isn't I do apologise, i've been talking to my friend who does
ASP.net and he said he was sure there is for PHP.

Hi Tom,
Thanks for the reply, I believe I have a fair understanding of
functions, and I have followed the example on the PHP manual page (
http://uk3.php.net/manual/en/function.date-diff.php
), ideally I want to know how to use the class DateTime::diff, how
can I use the DateTime::diff to get the difference between two times/
dates ? I suppose then I'm after the syntax
would it be like this for example:
$DIfferenceInTime = DateTime::diff(10:00,12:32);
Thanks again for helping me out.

Do you understand how to use functions?
A function is defined like this:

You can pass arguments to be used in a function like this:
function($arg1, $arg2) {
//code goes here
}
In the first example on the following page:
http://uk3.php.net/manual/en/function.date-diff.php
To call the function you need to provide two arguments: $dtTime1 &
$dtTime2
To use in a script, you need to first define the function, as per
the example:
format("Y-m-d H:i:s"));
$nUXDate2 = strtotime($dtTime2->format("Y-m-d H:i:s"));
$nUXDelta = $nUXDate1 - $nUXDate2;
$strDeltaTime = "" . $nUXDelta/60/60; // sec -> hour
$nPos = strpos($strDeltaTime, ".");
if (nPos !== false)
$strDeltaTime = substr($strDeltaTime, 0, $nPos + 3);
return $strDeltaTime;

Then you need to call the function like this:
And it should spit out the difference.
Code is untested and if you didn't follow that I suggest you read up

Hello,
My journey of learning PHP is going well, so i've decided to make a
small program which works out the difference between two times and
records the data in a text file.
I've searched the PHP manual for functions which can help me out,
and I discovered the function Date_diff (
http://uk3.php.net/manual/en/function.date-diff.php
)and the class DateTime::diff (
http://uk3.php.net/manual/en/datetime.diff.php
)
My question is, how on earth do I use these functions ? I really
don't understand the manual documentation.
I've just moved onto the subject of classes and so I'm fairly new to
the concept, although I am following it well.
If someone could explain to me how to use ether of these ( Date_diff
and DateTime::diff ) I would be VERY grateful.
Thank you so much!
Matt

Hi,
This is a quick function that works using unix time stamps. Its a
bit quick and messy but
works ok. Take a look at the manual page for the strtotime()
function to get a better idea
of what it can handle.
0,
"Hours" => 0,
"Minutes" => 0,
"Seconds" => 0
);
$amounts= Array(
"Days"=> 60*60*24,
"Hours" => 60*60,
"Minutes" => 60
);
$difference = $Date2_UnixTimeStamp - $Date1_UnixTimeStamp;
if($difference >= $amounts["Days"]){
$return_difference["Days"] = floor($difference /
$amounts["Days"]);
$difference -= $return_difference["Days"] * $amounts["Days"];
}
if($difference >= $amounts["Hours"]){
$return_difference["Hours"] = floor($difference /
$amounts["Hours"]);
$difference -= $return_difference["Hours"] *
$amounts["Hours"];
}
if($difference >= $amounts["Minutes"]){

Re: [PHP] difference between two times? Date_diff and DateTime::diff
Hi Tom,
Thanks for the reply, I believe I have a fair understanding of
functions, and I have followed the example on the PHP manual page ( http://uk3.php.net/manual/en/function.date-diff.php
), ideally I want to know how to use the class DateTime::diff, how
can I use the DateTime::diff to get the difference between two times/
dates ? I suppose then I'm after the syntax
would it be like this for example:
$DIfferenceInTime = DateTime::diff(10:00,12:32);
Thanks again for helping me out.

Matt,
Do you understand how to use functions?
A function is defined like this:
function () {
//code goes here
}
You can pass arguments to be used in a function like this:
function($arg1, $arg2) {
//code goes here
}
In the first example on the following page:
http://uk3.php.net/manual/en/function.date-diff.php
To call the function you need to provide two arguments: $dtTime1 &
$dtTime2
To use in a script, you need to first define the function, as per
the example:
format("Y-m-d H:i:s"));
$nUXDate2 = strtotime($dtTime2->format("Y-m-d H:i:s"));
$nUXDelta = $nUXDate1 - $nUXDate2;
$strDeltaTime = "" . $nUXDelta/60/60; // sec -> hour
$nPos = strpos($strDeltaTime, ".");
if (nPos !== false)
$strDeltaTime = substr($strDeltaTime, 0, $nPos + 3);
return $strDeltaTime;
}
?>
Then you need to call the function like this:
And it should spit out the difference.
Code is untested and if you didn't follow that I suggest you read up
on functions: http://www.w3schools.com/php/php_functions.asp
Hope this helps - I'm probably in a similar situation to you and
have been dabbling with PHP for a few years just as a hobby but
thought I'd try and help out.
You'll learn a lot from reading this list as well.
Cheers and good luck,
Tom

Hello,
My journey of learning PHP is going well, so i've decided to make a
small program which works out the difference between two times and
records the data in a text file.
I've searched the PHP manual for functions which can help me out,
and I discovered the function Date_diff ( http://uk3.php.net/manual/en/function.date-diff.php
)and the class DateTime::diff ( http://uk3.php.net/manual/en/datetime.diff.php
)
My question is, how on earth do I use these functions ? I really
don't understand the manual documentation.
I've just moved onto the subject of classes and so I'm fairly new to
the concept, although I am following it well.
If someone could explain to me how to use ether of these ( Date_diff
and DateTime::diff ) I would be VERY grateful.
Thank you so much!
Matt

[PHP] difference between two times? Date_diff and DateTime::diff
Hello, My journey of learning PHP is going well, so i've decided to make a small program which works out the difference between two times and records the data in a text file.
