PHP - Calculating A Timestamp
I have a timestamp field in my mySQL table and need to check if it's 14 day or older. What's the best way to do this?
Any help will be appreciated Similar TutorialsI have a form that I will post the code for. In my form I have a few things that need to be filled out.... Age, Gender, Coverage Amount, and Health Conditions. The Health Conditions are 5 check boxes the user can select. Now what I'm trying to do is make it so that when the user hits submit the Age and number of Health Conditions checked off will do this... if # of Health Conditions <=2 and Age is <= 30 then = $0.90 if # of Health Conditions =>2 but <=5 and Age is <= 30 then = $1.20 Then after those are calculated I need these to apply to the code... - Men are charged a 5% gender risk - Students receive an 8% discount Here is a example of what I'm trying to get this to do... If you are a 23 year old male student who smokes but has no other risk factors your premium amount per $10,000 would be $0.90 * 1.05 * 0.92 = $0.8694. If you wanted to take out a $150,000 life insurance, your monthly premium would be $13.04 (15 * $0.8694). I'm doing a life insurance form and these are some of the calculations that need to go into it. I'm not sure how I would code these. If someone could help me get started that would be great. Here is my form code and the display page.

Just looking for someone to help me get going, and show me how to do this. Need helping calculating text boxes on a form. I want my form to display the premium of $10,000 health insurance. What I mean by this is that I have a form that involves filling out life insurance information. This is the table I'm basing this off of... Age <=30 #health conditions <=2 $0.90 2 <= #health conditions <=5 $1.20 The number of health conditions is equivalent to the number of check boxes that were checked.

When I add say: 500 seconds to the current time it adds a whole lot more and I get a number few thousands higher than I want. Can anyone help me???. Gr Ryflex hey guys just a quick onei having a blank moment i have an array at themoment pulling from a database. i basically want to split this array based on a min and max value. divide it equally and then give it a value on each smaller array and where each array starts... to make it clearer - say i have an array with 600 values in i want it split up into 8 smaller arrays link so Array ( => Array ( [start] => 0 [split] => 75 ) [1] => Array ( [start] => 75 [split] => 75 ) [2] => Array ( [start] => 150 [split] => 75 ) carrying on till the end ) how would i do this. Hello, I am having a heck of a time trying to get time right on my website lol When a user logs in, they select what timezone they are in (UTC -1,-2,-3,-4,-5,-6....) Now this is great an all, but with daylight savings time my times are off by one hour in either direction. How do sites like this get times to work for users so easily? Thanks! weee Hello Please take a look at attatchment: Lets say for example I wanted to check the streak of clan1 (column) = 9 (rows) The streak would be 5 because each row has score1 greater than score2. So I want to calculate the streak of the value in clan1 column that has score1 greater than score2 in rows, if score2 is greater than score1 in a row then the streak breaks if that makes sense? let me know if I need to re-phrase. Secondly, if there are two streaks, I want it to calculate the highest one. Thanks for any help !! Hi, This query will show match stats of a user, the query is the output in the attatchment. I want to calculate the streak if score1 is greater than score2. So basically, in the attatchment I have selected 3 rows, these 3 rows should be a 3 streak because the user won 3 matches in a row (according to date) Code: [Select] SELECT * FROM webs_cup_matches WHERE ladID='17' AND (clan1 != '0' AND clan2 != '0') AND (clan1='2630' || clan2='2630') AND (clan1 != '2147483647' AND clan2 != '2147483647') ORDER BY date DESC any help appreciated. Hi, im trying to calculate and display a time elapsed from known date in db. however im having trouble displaying it. other values display no problem, just cant calculate and display date on the fly. does anyone see a problem with my query? thank you. Code: [Select] <?php include('config.php'); $uname=$_SESSION['username']; if($_SESSION['username']){ $sql="SELECT country, nationality, passportDate FROM country WHERE uname='$uname'"; $result = mysql_query($sql) or die(mysql_error()); $passportDate _ts = strtotime($row['passportDate ']); $passportDate _str = date("M-d-Y", $passportDate _ts); $TotalTime = floor((time() - $passportDate _ts)/(60*60*24)) . ' days'; while($row=mysql_fetch_array($result)) { echo "<table border='0'> <tr> <th>Nationality</font></th> <th>Country</font></th> <th>Passport Seent Date</font></th> <th>Time Elapsed</font></th> </tr>"; echo "<tr>"; echo "<td>" . $row['nationality']."</td>"; echo "<td>" . $row['country'] .

It has columns that go back 26 months. The columns are SALES_OLDEST_PD_1, SALES_PD_2, SALES_PD_3, ..... SALES_PD_25, SALES_LAST_PD_26, & SALES_CURR_PD_27. SALES_CURR_PD_27 is the current month. I want to build a table with "Last Year To Date Sales" (LYTD), "Current Year To Date Sales" (CYTD), (May 2011), and (May 2010). I know that (May 2011) will be SALES_CURR_PD_27 and (May 2010) will be SALES_PD_15. The trick is that the sales year starts in November. So, I need to figure out a way to match the table columns with "Nov. 09 - May. 10 TOTAL" for (LYTD) and "Nov. 10 - May. 2011 TOTAL" for (CYTD). I am familiar with using mktime() to subtract months. But, I am not sure where to start yet on this project. Jake Code: [Select] while (odbc_fetch_row($rs)) { $M1 += odbc_result($rs,"SALES_OLDEST_PD1"); $M2 += odbc_result($rs,"SALES_PD2"); $M3 += odbc_result($rs,"SALES_PD3"); $M4 += odbc_result($rs,"SALES_PD4"); $M5 += odbc_result($rs,"SALES_PD5"); $M6 += odbc_result($rs,"SALES_PD6"); $M7 += odbc_result($rs,"SALES_PD7"); $mate += odbc_result($rs,"SALES_PD8"); $M9 += odbc_result($rs,"SALES_PD9"); $M10 += odbc_result($rs,"SALES_PD10"); $M11 += odbc_result($rs,"SALES_PD11"); $M12 += odbc_result($rs,"SALES_PD12"); $M13 += odbc_result($rs,"SALES_PD13"); $M14 += odbc_result($rs,"SALES_PD14"); $M15 += odbc_result($rs,"SALES_PD15"); $M16 += odbc_result($rs,"SALES_PD16"); $M17 += odbc_result($rs,"SALES_PD17"); $M18 += odbc_result($rs,"SALES_PD18"); $M19 += odbc_result($rs,"SALES_PD19"); $M20 += odbc_result($rs,"SALES_PD20"); $M21 += odbc_result($rs,"SALES_PD21"); $M22 += odbc_result($rs,"SALES_PD22"); $M23 += odbc_result($rs,"SALES_PD23"); $M24 += odbc_result($rs,"SALES_PD24"); $M25 += odbc_result($rs,"SALES_PD25"); $M26 += odbc_result($rs,"SALES_LAST_PD26"); $M27 += odbc_result($rs,"SALES_CURR_PD27"); } Note: By the way SMF is changing $M"8" to $M"ate". lol I tried using a for loop but I'm trying to think of a way to calculate interest for a number of years but after I have the amount of interest for one year I'm unsure of how to add the interest to the principle then calculate it again for the next year, to hold that number like $Principle + $Interest = $NewPrinciple then $NewPrinciple + $Interest for multiple years.
<?php
if (isset($_POST['submit'])) {
$InvestmentFrequency = $_POST['InvestmentFrequency'];
$CompoundFrequency = $_POST['CompoundFrequency'];
$InitialInvestment = preg_replace("/[^0-9]/", '', $_POST['InitialInvestment']);
$Contributions = preg_replace("/[^0-9]/", '', $_POST['Contributions']);
$InvestmentLength = preg_replace("/[^0-9]/", '', $_POST['InvestmentLength']);
$InterestRate = $_POST['InterestRate'];
if ($InvestmentFrequency == "Weekly") {
$InvestmentFrequency = "52";

$CompoundFrequency = "12";
} elseif ($CompoundFrequency == "Weekly") {
$CompoundFrequency = "52";
} else {
$CompoundFrequency = "365";
}
if ($CompoundFrequency == "1") {
$AdditionalInvestments = $Contributions * $InvestmentFrequency;
$Principle = $InitialInvestment + $AdditionalInvestments;
$Interest = $Principle * $InterestRate;
$NewPrinciple = $Principle + $Interest;
for ($x = 0; $x <= $InvestmentLength; $x++){
echo "$x - $NewPrinciple</br>";
}
}
}
This is the output I get the principle and interest added together for the number of years I entered. Edited July 26, 2020 by dataxspy I have this block of code that was written by someone years ago :-
<?php

public function EstimatedDays($off, $standard_days, $saturday, $delay) {
$today = date("N"); // Weekday - number 1-7
$now = strtotime("now"); // Unix

$off_unix = mktime($off_array[0], $off_array[1], "00", date("n"), date("j"), date("Y"));
$sending_days_from_now = 0;
if ($now > $off_unix) {
$sending_days_from_now++;

Which is supposed to calculate the number of days for delivery, taking into account weekends & with a delay variable that we can set. It isn't working as expected, may never have worked(??) or maybe down to PHP upgrades. For example, if today (18th)I set the delay to 2 days the delivery estimate is the 21st (which is correct), if I change the delay to 3 OR 4 it becomes the 24th, 5 then becomes the 26th! I can't get my head around the code at all, I wonder if someone could assist in what may be going on or add comments to the code snippets so I can maybe work it out?
Thanks for any help. Hey everyone, Im writing some code that has to work out a route based on linking airports and output all the flights it takes to get there, tried searching just dont really know what to search for The data table looks like this ID, Origin, Destination, DatetimeDeparting, DatetimeArriving, Price 1, BKK, CNX, 2010-10-14 12:00:00, 2010-10-14 14:00:00, 125 2, STN, BKK, 2010-10-13 18:00:00, 2010-10-13 22:00:00, 300 etc. What is the easiest way of working out the path from STN to CNX via BKK? UPDATE: Just to make it more interesting there will be instances where there is more than 1 path eg. STN -> KUL -> BKK -> CNX hi all, i'm trying to calculate the time difference between two dates in hours, for example: 2010-12-13 15:26:56 and 2011-12-13 15:26:56 i tried mktime but wasn't able to get a working function. Thanks for the help Okay guys, I figured out how to calculate monthly subscriptions into days, but I am stuck on calculating multiple monthly subscriptions.. for example Heres my mysql table: How would I calculate this: Subscription Start: February 21, 2011, 12:00 am Subscription End: April 22, 2011, 12:00 am Subscription Left: 60 days My trouble is that when the user buys another month, it calculates the end time based on the new "Subscription Start Date". Or vice versa. Any ideas guys? Thanks. Hello Please can someone PLEASE PLEASE help me. I have a form that the user inputs dimension and weights of a parcel. They then request a price on request I do the following: $volume_mass = 50(dimm1) *50 (dimm2) * 50 (dimm3); so that means $volume_mass = 125000 I then take the total of the weight - $actual_mass = 20(weight) I am doing the following query to see what service are available $data = "SELECT * FROM rates WHERE hub_from = 'nxd' AND hub_to = 'auk'"; $result = mysql_query($data) or die ("Error in query: $data. " . mysql_error()); if (mysql_num_rows($result) > 0) { while($row = mysql_fetch_object($result)) } ?> So I get multiple results and I need to now work out the cost per result. Example of results from rates table $service $volume $base $min_kg $per_kg AIR 5000 70.00 5 4 ECO 4000 80.00 10 4 LOX 5000 45.00 1 35 LSE 5000 45.00 1 35 OVN 5000 70.00 10 4 Know I need to do the following per result (per service) need to the volume factor from the service - &totalv = $volume_mass / $volume (from the rates table) Check if which is now greater between $actual_mass and $totalv - $charge_mass = $actual_mass <> $totalv then need to calculate the costs - if $charge_mass <= $min_kg then $total_cost = $base echo "$total_cost" else if $charge_mass > $min_kg then $total_cost = ($charge_mass - $min_kg) *$per_kg + $base echo "$total_cost" Any help would be greatly appreciated I have collected some data from .xml api's and I need to manipulate it in a way to display something specific.
not my strongest point when it comes to maths & date data.
so ultimately I need it to echo something like the following:
"3 Days 4 Hours Remaining" or "14 Hours Remaining" (if below 24 hours!!!)
I use the following to pull my variables and to test by echo results.
<?php // Calculate total Fuel blocks
$itemID = $record['itemID'];
$result = mysql_query("SELECT * FROM `ecmt_poslistdetails` WHERE itemID = '$itemID' AND (typeID='4051' OR typeID='4247' OR typeID='4246' OR typeID='4312')");
$row = mysql_fetch_array($result);
$fuelQty = $row[quantity];
echo $fuelQty;
?>
<br />
<?php // Calculate total Fuel blocks used per hour
$typeID = $record['typeID'];
$result = mysql_query("SELECT * FROM `ecmt_posfuel` WHERE typeID = $typeID");
$row = mysql_fetch_array($result);
$fuelUse = $row['fuel'];
echo $fuelUse;
?>
this gives me:
$fuelQty & $fuelUse
so for instance if fuel quantity is: 18480
and $fuelUse is: 40
the fuel used is 40x per hour and time remaining would be 462x Hours remaining but I want it to display: 19 Days 6 Hours Remaining
how can I achieve this format?
Hi guys! This will seem complex but I really need your help If a have a variable with a date value (i.e. $a = '23/10/2011') How do you work out the week number of that date? Thanks hi all. just some background info: im new to php and im also not a programmer so go slow if replying looked around the internet for any php info i can find on computing a response for the digest md5 challenge of a server and cant find a thing. here are some references: http://www.ietf.org/rfc/rfc3920.txt http://www.forumeasy.com/forums/archive/ldappro/200606/p115022055514.html http://commons.apache.org/codec/apidocs/org/apache/commons/codec/digest/DigestUtils.html http://www.coderanch.com/t/472230/java/java/SASL-Authentication-XMPP im thinking (really just assuming) that one of the strings need to be converted into an ascii character mapping, then stripped of it's 0x value and then hashed.... but like i said, im a newbie so asking for an explanation of this in php... please dont refer to a class or function, i want to understand the steps involved too. thanks in advance! Hey guys,
I need some help with a simple script a friend wrote for me but isn't returning the correct values. I'm looking to get this script working but my PHP skills are abysmal and I can't for the life of me figure out whats the best way to do this. I've tried contacting my friend but he's moving cross-country so I'm hoping you guys can give me some advice.
The script is supposed to return a total shipping price based on the weight of products that are passed to it via an API and the location of the visitor. There are a total of 3 different products (Product A, Product B, Product C) each with it's own weight in grams and it's own shipping rate. The script is needs to follow the following rules:
When 1 product (either Product A, B, or C) is in the cart it returns the full fixed shipping price for either US or International Shipping based on $isInternational
When 2 or more of Product A or B are added to the cart the full shipping is taken for the heaviest item and a fixed price is added for each additional item (Product and B each have their own fixed prices)
When Product C is added to the cart it returns a fixed based on US or International (Product C ships separately and doesn't depend on the weight/prices of Product A or B)
The product weights/prices a
