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:

Calculate The Number Of Days Between A Given Date And The End Of The Month.
I was hoping someone can help me with a date calculation. I'm trying to calculate the number of days between a given date and the end of the month. I have a form with three drop down boxes: month, day and year. A user will submit a date using these drop down boxes. Based on their submission, I need to determine the number of days to the end of the month from the date which was submitted. For example, if the person submits March 15, 2007 and the last day of the month of March is March 31, 2007. The number of days between the 15th and the last day of the month is 17. How do I begin programming this calculation? Since the last day of the month differs from month to month (28th, 30th or 31st) I cannot figure out how to determine the last day of a given month.

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.

Calculate Days Worked
I have a set date in my MySQL database that records when a Sales Lead is established and I echo that date as $row_rsLead['lead_date']; I need to be able to calculate how many days that lead has existed. $row_rsLead['lead_date']; outputs as 2007-06-14. I have made numerous attempts to create a function that will calculate the days between the lead_date and today's date, but have made absolutely no headway. I am either stuck working between differing date formats or really strange numerical outputs. If there is a script someone is willing to share or point me in a direction that is good for a relative newcomer to PHP,

Calculate A Number And Output It As An Image Using Img Tag?
Is it possible to point to a php file from an image tag like so: <img src="http://otherdomain.com/getNumberOutputAsImage.php"> which would go to the php file, do its calculations, determine a number, then output that number as a graphic? Do you know what I mean? P.S. now that I think of it, I have another thought. I heard that sites like doubleclick have their banner ads all over the place and using only the image tag, manage to set a cookie cross-multiple domains. Is this true? I have a couple of domains linked together and would love to be able to maintain the login state through a cookie. Is this possible?

How To Add X Number Of Days To A Date
I have been scratching my head over this one. I want to add a number of days to a date and end up with a date. The only way I've thought of doing this so far is converting to a time stamp, adding the days (in milliseconds) and then converting back. I'm sure there must be an easier way!

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?

Add X Number Of Days To Today's Date
I have been looking through this forum and discovered that the way most people add X number of days to today's date is using this code: echo mktime(0, 0, 0, date("n"), date("j") + 10, date("Y")); When I do this, I get an output similar to this - 1156114800 I am not sure what I can do with this, I am trying to compare it to a date pre-entered into mysql. I also tried using strtotime("+1 day"), with a similar output again.

Number Of Weekdays Between 2 Dates.
I'm looking for a way to find the number of weekdays between 2 dates In my form I have three fields for a begin date (dd)(mm)(yyyy) and three for the end date (dd)(mm)(yyyy). Now these values will be stored into a database and at the same time there will be an e-mail generated and send to me that contains the starting date en the end date . But now I want an extra line in this e-mail that tells me howmany days there are between the starting date en end date so that the e-mail contents looks something like this. Begin date : (dd) (mm) (yyyy) End date : (dd) (mm) (yyyy) Days between (number of days) so lets say starting date is 01/01/2003 end date is 15/01/2003 then the number of days between should say 11 (01-02-03-06-07-08-09-10-13-14-15 /01/2003) I realy hope someone would be so kind to give me a solution on my problem.

Start Date - End Date = Number Of Days
I have a starting date for var 1 and today’s date for var 2. I need to calculate how many days are between those two dates. 02/24/03(today) - 01/14/2002(start date) = number of days. In theory this is easy but there are many instances were I could get an inaccurate answer. For example one consideration is that some months have 30 days others have 31. exc. My question is, is there an easier way to solve this problem other than using endless if statments to error handle all possible instances? Does PHP4 have any built in functions that could calculate this formula correctly?

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.
