PHP - Php Fuction For Multiplying Numbers
Is there any function in php lib that does the following $a = 1238; $n = 48; // 1*2*3*8 or I will have to create one for my script? (I want to do it for both client and server sides based on request sent by user. I actually want it in php that is why i asked it here, but if the solution (as function) is available in javascript (not jQuery) please share or guide me.)

The procedure is supposed to be, you choose a hotel ---> book a room ---> confirm the booking and enter your details --> get redirected to paypal Everything is fine except for the confirmation part, where you're supposed to confirm the room you booked, number of nights and so on, all the info is right, except for the booked room, where it should show you the price for the room multiplied by the number of night... instead it gives "Total Price = 0" So anyone can give me an example on how can I make it show the result of multiplying 2 inputs by a user? Variables are $nrooms $newdate Here is the code I wrote Code: [Select] <?php $dbo = new DB(); $hotelObj = new hotelManager(); $hotelID = $_POST['hotelid']; $datein = $_POST['datein']; $dateout = $_POST['dateout']; $roomid = $_POST['roomid']; $roonsNo = $_POST['roomsNo']; $pr = $_POST['pr']; $_SESSION['hotelID'] = isset($_POST['hotelid']) ? $_POST['hotelid'] : $_SESSION['hotelID']; $_SESSION['datein'] = isset($_POST['datein']) ? $_POST['datein'] : $_SESSION['datein']; $_SESSION['dateout'] = isset($_POST['dateout']) ? $_POST['dateout'] : $_SESSION['dateout']; $_SESSION['roomid'] = isset($_POST['roomid']) ? $_POST['roomid'] : $_SESSION['roomid']; $_SESSION['nrooms'] = $_POST['nrooms']; $roomsarray = explode(",",$_POST['roomid']); $_SESSION['roomsarray'] = isset($_POST['roomid']) ? explode(",",$_POST['roomid']) : $_SESSION['roomsarray']; $roonsNo = $_POST['nrooms']; $_SESSION['nrooms'] = isset($_POST['roomnum']) ? explode(",",$_POST['roomnum']) : $_SESSION['nrooms']; /********************** hotels ************************/ /******************************************************/ echo "<table width=95% border=0 align=\"center\" cellpadding=\"0\" cellspacing=\"0\"> <tr><td valign=\"top\">"; echo "<table>"; echo "<tr>"; echo "<td valign=top>"; $imageqry=mysql_query("SELECT * FROM `hotelphotos` where hotel_id='".$_SESSION['hotelID']."'

The basic principle of what I want to do is: ounit1 number (members table) * ounit1 power (ounit table) ounit2 number (members table) * ounit2 power (ounit table) etc to unit12. The members table has the fields: username ounit1 ounit2 ounit3 ounit4 etc for the number of units. The Ounit table has the fields: Ounit (primary auto increase) opower and a few more that are not needed for this. So basically, it it possible to call data from two different tables and multiply it? So far I've got: Code: [Select] <?php $result = mysql_query("SELECT * FROM members WHERE Username='$_SESSION[Username]'") or die(mysql_error()); while($row = mysql_fetch_array( $result )) { echo '<b>Power</b><br />'; echo 'Offence: ' . $row[''] . ' <br />'; echo 'Defence: ' . $row[''] . ' <br />'; echo 'Power: ' . $row[''] . ' <br />'; } ?> I'm not sure how to call two tables at once. Any help would be great! Hi, I need to sort variables in groups of up to 15 and put it in an array. For example: $exstract['center_tabOpBody_0'] =5 $exstract['center_tabOpBody_1'] =6 $exstract['center_tabOpBody_2'] =8 $exstract['center_tabOpBody_3'] =1 Should yield: ARRAY( = center_tabOpBody_1,center_tabOpBody_2,center_tabOpBody_3 // <-----15 [1] = center_tabOpBody_0 //<----5 ) Is there some simple function do do the "efficiency" sort? Thanks, Vadim can you have something like.. echo $whatever; this putput 1.2 can you split this number so the first integer will be in $val"(1)" or whatever and the second integer after the "." will be in $val2"(2)" if (preg_match($fname [0-9])) { echo "invalid FirstName"; } want the user to only be able to enter letters this is the code i have assuming that preg_match will spot any number in the $fname field and print "invalid firstname" if the user entered a number. how can i get the users to only insert letters? This is my current script <?php $iFile = "accounts.txt"; //Put your list lagger's info in this txt file in the same directory as this script. Format is UserID(space)AuthKey $login = file($iFile, FILE_SKIP_EMPTY_LINES); if(!is_file($iFile)) echo "The logins file couldn't be found...".sleep(999999); foreach($login as $line_num => $line) { $login = explode(" ", htmlspecialchars(str_replace(" "," ",$line))); //////////////// ////////////// /////////// ///////// if(stristr($login[1], "\n")) $login[1] = substr($login[1], 0, strlen($login[1])-2); $MobLink = "http://mobsters-fb-apache-dynamic-lb.playdom.com/mob_fb/"; $RefreshStat = file_get_contents($MobLink."refresh_stat?user_id=".$login[1]."&auth_key=".$login[0]); $Mob_Name = explode("<mob_name>", $RefreshStat); $Mob_Name = explode("<", $Mob_Name[1]); $Name = $Mob_Name[0]; $Cash = explode("<cash>", $RefreshStat); $Cash = explode("<", $Cash[1]); $CurrentCash = $Cash[0]; echo $Name."-$".number_format($CurrentCash)." - ".$login[1]."\n"; } sleep(99999); ?> The Script runs through for 100 different accounts, is it possible to add all the Cash values that get echo'd? Hey i'm just woundering how i would echo numbers from a database like 1000000 lets say 1 million how would i go about on echoing it like this 1,000,000 ZhsHero is this a proper way of entering this? Code: [Select] $result = mysql_query("SELECT * FROM jobs WHERE id2 >= '$startdate' AND id2 < '$enddate' ORDER BY id"); Hi i got an error. I cant get $new_score and $new_played variables. $name = $_POST["name"]; $score = $_POST["score"]; $result = mysql_query("SELECT * FROM taure_lentele WHERE name='$name'"); $row = mysql_fetch_array($result); if(mysql_num_rows(mysql_query("SELECT name FROM taure_lentele WHERE name='$name'") ) == 1 ) { $old_score = $row['score']; $score + $old_score = $new_score; $old_played = $row['played']; $new_played = $old_played++; mysql_query("DELETE FROM taure_lentele WHERE name='$name'"); mysql_query("insert into `taure_lentele` set `name` = '$name', `score` = '$new_score', `played` = '$new_played"); } I have a cards array, and I have this function which will shuffle the cards for me. How can I edit this to 'deal' 12cards (6 & 6) until all the cards are a specific 6 & 6 I pick out?

Please advise.. This is the current code I am working with but doesn't work. The problem is that explode won't work without some type of separator. Code: [Select] $height2 = explode(" ", $height); echo "This is feet". $height2[0] ."<br>"; echo "This is inches". $height2[1]. "<br>"; hello again how to get ratio with result max 3 numbers such as 3.00 or 0.11 if im do $mynumbers = 1000 / 400; so reusult to be 1.00 ? and how to put full stop if it is more then 4 numbers result instead of 1000 to have 1.000 Hi Guys
I have a regex conundrum that at first I thought would be very easy but then appears to be quite hard :/
I want to match a string with a regex where the regex can only pass if it contains letters and numbers (nothing else) and it has to contain at least one of each.
I've been trying out lookaheads but just can't get it right.
Any help is appreciated.

Hey I have a quick question. I am trying to have a part of this PHP script compare two numbers. There is a randomly generated two-digit number named $random and There is another two digit number named $number. I want to make it so the PHP checks to see if $number has any of the same charcters as $random. I don't know how to do this though. I suspect that somehow both numbers need to be broken apart somehow. Any advice would be appreciated. Let me know if I should explain it more clearly Thanks a ton! Sorry if this has already been solved. Also, I apologize if this is an amateur question... I have a simple form and a script to do some validating of user data, among other tasks. One part of the script is intended to verify a birthday. Code: [Select] $x = $_POST['x']; $x = trim($x); According to the php.net manual, trim() is supposed to remove whitespace before and after a string. My intent by using trim() is to determine if someone tried to skip the birthday field. I have other validation running on the value of $x, but I wanted trim() to remove whitespace. However, the value of x, which in this case is expected to be numeric, such as 12 for a month, ends up being 1. This happens with any 2-digit number that a user might enter into the form field for x. The second number is always removed. Any insight into why trim() removes the second number, 2 in the above example, leaving only a "1" as the value of $x, would be very greatly appreciated. Thanks in advance. |
