Calculating Days Between Two Dates
I need to calculate the numbers of days (only the number of days) between two days, one a variable $row['user_cp_name'] in the format MM/DD/YY, and another, the current time. I've tried a bunch of tutorials on the internet and none seem to work properly.

Calculating The Number Of Days
I have a bit of a problem calculating the number of days chosen for a report. This is what I wrote: $start = mktime(0, 0, 0, $month1, $day1, $year1); $end = mktime(0, 0, 0, $month2, $day2, $year2); $days = (($end - $start)/(60*60*24)) + 1; where the values for $month1, $day1 etc. are selects in a form. The starting and end dates must be different. This seems to work mostly except for some cases e.g. Jan-01-2006 to May-01-2006 which gives me "120.95833333333 days". Any idea what I am missing?

Calculating Days From NOW From Future Datestamps
Hi All,I have datestamps of the format 11202006 (November 20th 2006) in the DB. All these datestamps are of the future. With reference to the datestamp, I need to query the database for all entries that are 90, 60, 29, 28, 27, 26, ... 02, 01 days away from NOW. So, if there are entries with datestamps 90 days from NOW, they will need to be displayed.The query will be run everyday through a CRON script. How do I create the queries? Would there be multiple SELECT queries? Eg: 90, 60, 29 .. 02, 01

Calculating Future Dates
I have a variable ($today) that is simply $today = date("m/j/Y"); I want to get another variable for x months down the line, but using the php.net reference of the mktime and date command, my second date, as follows comes out in a large number. How can I make sure it is forwarding the date properly, and format it like mm/dd/yyyy? This is the line from php.net reference page. I need this to calculate properly, and format mm/dd/yyyy - just like my variable up top. $two_months_from_today = mktime(0,0,0,date("m")+2 ,date("d"),date("Y"));

Calculating Dates From A Date In The Database?
I`m using this format of dates: $entry_date = strftime("%B %e, %Y %H:%M:%S", time()); And that time gets saved into the database (birth in ownedpets database): $res = mysql_query("SELECT id, owner, pet_type, pet_name, birth, food, play, datetime FROM ownedpets WHERE id=$id"); $rows = mysql_fetch_row($res); mysql_free_result($res); So let`s say in this case, the database birth value ($rows[4]) is October 19 2007 20:00:00. What do I do to tell php to check to see if the current date (hours and all don`t matter) is 21 days after the $rows[4]? Why I`m looking for this task: For the pets system, if the pet is 21 days after it`s birth, it will be an adult. But if it is not 21 days after it`s birth, it will still be a baby.

Calculate Number Of Days Between Two Dates
I have people posting ads and when the ad is posted I have two fields populated at that time: date_created date_expired With the date expired being 7 days after the date created. Both are in this format: 03/12/07 What I am doing is preventing someone from posting more than one ad per 7 days. I'm validating against their email address for that. But I want to display the date that they would be eligible as well as determine if they are eligible to post or not which would require comparing today's date with probably using the now() function against the date_expired in the database. If the today's date is past then no problem. If not, then it would display an error. Code:

How I Could Compare Two Dates To Find The Number Of Days That Seperate Them.
I was wondering how I could compare two dates to find the number of days that seperate them. For instance, after a user signs up to my website, they would see a specific message for only a week. Obviously this is easy if they signed up on the 14th and today is the 16th, but what about if they signed up on the 29th, then I need to figure out for the next month.

Dates In Range Falling Between Existing Dates
The latest quandry I have is that I need to: a: check whether any dates in a date range entered by a client in a form (datefrom, dateto) conflict with any existing date ranges already in the database. -this is a check to see whether the dates that a customer is trying to book are not already booked- Obviously its easy to get the numbers out of the database (i.e. 28/12/2006 or whatever format) and from the form but how to I convert this 'range' actually into a range I can loop through that will return true if any of the dates are the same (i.e. already booked)? b: is similar in that I want to check how many of the clients entered dates fall into the pre assigned high, mid and low season ranges in the database and multiply each of those days by the corresponding price.

Calculating Tax
I have a the following tax table which shows tax calculations on wages. The way it works is that you find the row where your annual wage is between the lower and upper limits. Then the difference between your wage and the above column is multiplied by the rate. You then add the last column to your result.Code: Lower Upper Percent Above Also Add 0 2,650 0.0%00 2,650 10,120 10.0% 2,650 0 10,120 33,520 15.0% 10,120 747.00 33,520 77,075 25.0% 33,520 4,257.00 77,075 162,800 28.0% 77,075 15,145.75 162,800 351,650 33.0% 162,800 39,148.75 351,650 and over 35.0% 351,650 101,469.25 Note: Lower limit = last upper limit; above = last lower limit; also add = (last upper - lower)*last percent. Example: Say you earn 15,600 a year, you take: (15,600-10,120) * .15 + 747 = 1,569 how can you do this in PHP given these arrays:PHP Code: $LowerLimits = array(0,2650,10120,33520,77075,162800,351650);Â Â //must you have a 0? $Percents = array(0,.10,.15,.25,.28,.33,.35);

Calculating Tim - Easy For You! =)

This works even if we have the 1st of August $yesterday gives me the 31st july. Can I do this with times also? e.g. Iit it now 17:06 an i want to make minus 20 min (like abopve minus 1 day) and I want the result to be 16:46.

Calculating With The COUNT
I am writing a simple banner management script with three tables: banner, impression & clickthrough. Banner has three columns: banner_id (pk), banner_name & banner_url Impressions has 4 columns: impression_id (pk), banner_id (fk), banner_timestamp & banner_domain. Clickthrough also has 4 columns: clickthrough_id (pk), banner_id (fk), clickthrough_timestamp & clickthrough_domain. Every time a banner is shown, a record is created in the impression db and whenever one is clicked, the clickthrough db is similarly added to. My problem comes when trying to use SQL to get the conversion rate for any particular banner. For each banner I need to count the total records in the impression db and then divide it by the count from the clickthrough db. But I cannot for the life of me work out how to get counts from two tables and perform a mathematical operation on them.

Error Calculating
I'm getting an error and I really don't know why. I get the values from a form page and I add all the values put, to get a subtotal. So far, so good. It adds perfectly. I then get this subtotal value and multiply it by 2.35 to give it a total. It works great as long as the subtotal is under 1000. I don't know why it doesn't work. This is the part of the code where it doesn't work as I would like it to. All this is supposed to do is give the value of dollars in a foreign coin. echo 'Dollars:$'.$totalamount."<br>";//this works $totalamount = $totalamount * 2.35; $totalamount = number_format($totalamount, 2); echo 'Reais:$'.$totalamount.'<br>'

Calculating Timestamps
I have a mysql 3.23.58 server and php 4.2.2. I noticed that in mysql 3.23.58 when calculating a timestamp, lets say I am doing something like this in my sql. Code: select email from tbl_customer where date_added < current_timestamp and date_added > current_timestamp - 00000003000000; The date added field is actually a field that holds a time stamp. The zeros with the three represents three days before the current time stamp. I noticed that in mysql 3.23.58 it subtracts the days from 100 when the 2 digits in the timestamp that represent the month go to the previous month. In mysql 5 and newer the timestamp will calculate correctly.

Calculating My Wage
I would like to create a PHP-script where I can enter when I met at work, when I went home and how long a break I had. Then this should be multiplied with my hourly wage. For instance if I met at 10:00 am and left at 5:00 pm and had 1:00 hour break, my hourly wage would have to be multiplied with 6 hours. On monday-friday after 6:00 pm, on saturdays after 3:00 pm and on sundays I have an allowance which I would like to be added seperately. We could call them $eveall, $satall and $sunall (cause they are different). Finally I would like all this to be saved into a file and to be shown on my html-page with the script for each month from the 21th to the 20th (for instance should July be from June 21th to July 20th).

I'm working on a script that takes uploaded images and adds them to a database, but I'd like to check and make sure there's room for it first. I think there's probably going to be some type of issue with quotas, because that's how I found the problem. A user had uploaded a test version and got an error that a folder could not be created because of insufficient space remaining. And I know I could probably exec() out to df or something similar, but I would like it to work on Windows servers as well, so I'd prefer to keep it all in PHP code if possible.

Calculating Correct Time
Lets start off by giving you my code (Well the important sections of it!): <?php /**/# Total Time /**/$query = "SELECT sum(hours) FROM flights ".$condition; /**/$result=mysql_query($query); /**/$blcktime = number_format(mysql_result($result,0)); /**/$query = "SELECT sum(minutes) FROM flights ".$condition; /**/$result=mysql_query($query); /**/$blckmins = number_format(mysql_result($result,0)); echo "$blcktime:$blckmins"; ?> Okay this part works. Like if there is an entry that has 20 hours in hours table and 50 minutes in minute table it displays 20:50, but my problem is if there are more than one record (Which there will be) if the previous was still true and another record had 1:30 the total would be 21:80 but this of course is not correct addition of time. And this is not a 24 hour clock it simply displays the time someones been in a game so it can go lke 300:56 too. Now how would I get it so if the $minutes were greater than 60 and divisible by 60 it would add the correct numbers to the hours like $hours = $hours + $times_divisible; or something like that! I am okay with if..else..elseif statements but that would take forever to write. thats why I need a looping sttatement but I havent got a clue how to write it.
