PHP - Adding Foo Onto Bar (arithmetic)
I am trying to add foo onto bar inside a loop so I can then echo bar outside the loop and see the sum.
The PHP manual doesn't have anything on addition in the way I need it (adding onto), so I was wondering if anyone can help me? LOL embrace yourself! $query = "select * from products where id='{$content['id']}'"; $result = mysql_query($query); $row = mysql_fetch_array($result); mysql_query ($query); mysql_close($link); echo " <B>Product ID:</B> {$content['id']} <BR> <B>Price:</B> $row[price] AUD <BR> <BR> "; +$row[price] -> $total; } echo $total; Similar TutorialsSo I added a number unformatted and got the expected value, but after I formatted it I received an incorrect value? The Number unformatted looks like this: 441492111.66667. So did $number + 10 and got = 441492121.66667. That's all fine and correct. But after I formatted like so: $final = number_format($number) + 10; I got 451. Not too sure why that would happen, can someone explain to me please? Hello again. I run a sports league website and registrations received after a certain date need to have their league fees calculated to add 10%. someone wrote this for me a couple of years ago, but I have since then lost the full code. Need to know how to add a date to the follow statement that would automatically add the 10%. Can someone look at this for me and fill me in on what's missing? Thanks! Code: [Select] /* * Calculate fees */ $intSize = intval($arrLeagueSearch['size']); switch($intSize) { case 2: $dblBase = 150.00; $intBSize = 3; break; case 4: $dblBase = 330.00; $intBSize = 6; break; case 6: $dblBase = 550.00; $intBSize = 10; break; default: die("Invalid league size"); }; $dblEarlyTeam = $dblBase; $dblEach = $dblEarlyTeam / $intPlayers; /* $dblLateTeam = $dblEarlyTeam * 1.10; $dblLateEach = $dblLateTeam / $intPlayers; */ Hello I'm trying to use PHP "for loops" to build a table of 10 rows with 5 columns and I'm sure there's a better way to do this, but the result is the page won't fully load and continually spins its wheel. Here's the code: Code: [Select] $states = array(1 => 'AK','AL','AR','AZ','CA','CO','CT','DC','DE','FL','GA','HI','IA','ID','IL','IN','KS','KY','LA','MA','MD','ME','MI','MN','MO','MS','MT','NC','ND','NE','NH','NJ','NM','NV','NY','OH','OK','OR','OZ','PA','PR','RI','SC','SD','TN','TX','UT','VA','VT','WA','WI' ); <table id="stateCheck"> <?php for ($i = 1; $i <= 10; $i++) { echo '<tr>'; for ($j = 5*$i; $j <= $j+4; $j++) { echo '<td> <input type="checkbox" name="state" value="'.$states[$j].'" /> '.$states[$j].' </td>'; } echo '</tr>'; } ?> <tr> <td> <input type="checkbox" name="state" value="WV" /> WV </td> <td> <input type="checkbox" name="state" value="WY" /> WY </td> </tr> </table> Is it breaking because I'm using arithmetic operators to define the nested for loop? Many thanks hi i been working on this code witch will add what ever text i want to my database all is working great but what i am having problems with is inserting a url in the same field as vidID it will look like this in the database hxxp://xxx.mysitehere.com/index.php?vid=vidID hope you guys know what im talking about im having a hard time explaining it sorry. Code: [Select] <?php $host="xxxxx"; $username="xxxxxxx"; $password="xxxxxxx"; $db_name="xxxxxxx"; $tbl_name="xxxxxxx"; $message = strtoupper(trim($_REQUEST['message'])); $sender = strtoupper(trim($_REQUEST['sender'])); $email = strtolower(trim($_REQUEST['email'])); $vidID =$_REQUEST['vidID']; mysql_connect("$host", "$username", "$password")or die("cannot connect server "); mysql_select_db("$db_name")or die("cannot select DB"); $sql="INSERT INTO $tbl_name(message,sender,email,vidID)VALUES('$message','$sender', '$email', '$vidID')"; $result=mysql_query($sql); ?> This might be more of a mySQL question or a PHP question, I'm not exactly sure. I have a field in my table (Deals) called "Price". All I want is the sum of that field. I tried using something like: $price += $row['Price']; This ended up as one long string, even though the database is set as a decimal number field. Then I tried doing it from mySQL like this (from what I read), but I don't think I have the full answer: foreach($stmt->query('SELECT SUM(Price) FROM Deals') as $row) { echo "<tr>"; echo "<td>Total</td>"; echo "<td> ->".$row['SUM(Price)']."</td>"; echo "</tr>"; } Anyway, if someone could just show me how to get that sum, I would greatly appreciate it because I am missing something here. Hi can someone please show me how I should include a Code: [Select] <div id="css"></div> in this line Code: [Select] echo $AB_LANGS['CalendarInstructions']; I have tried several attempts with no joy. Many thanks hello. im trying to get the following to work. any ideas for me? Code: [Select] Text[12]=["Job Description","$description it "] it is in a .js file. Hi, I have a function that pulls a random line from a text file and I would like to change it so it pulls a random line from a text file that contains a certain date, heres the current function : Code: [Select] function RandomLine($filename) { $lines = file($filename) ; return $lines[array_rand($lines)] ; } Any ideas on the best way to do this ? Many thanks. I had this working before, but my coding structure has changed a bit and need help with syntax. My function I have down ok. function cssfrommvp($mvp) { $class = array('MVP' => 'MVP'); return $class[$mvp]; } this is how I would add the class to a <td> with $row. Code: [Select] echo "<td class=\"".cssfrommvp($row['mvp'])."\">".$row['mvp']."</td>\n"; now using $array <td> . $MVP .</td>\n</tr> how would I do the same thing as done before with $row? I created the code below and it outputs the following number output: 1111111773526604115551144611337112281111221111345 6789101121111100352004110051100611007110081100221 1003456789101141111100352004110051100611007110081 1002211003456789101151111100352004110051100611007 1100811002211003456789101123111110035200411005110 06110071100811002211003456789101134 Anyways if you look at the code, I need to be able to add the values on a single colony, idcol, with the same type and subtype, btid/stid, generated as the $prod variable. buildings with the same subtype generate the same resource, in this case, several iron mines and a single copper mine are present, but there are also 9 other types of resource buildings. How do I collect on the prods which go together?

I have seen somewhere that you can add to a string like so $var = "text"; or $string ="var"; &$var = "text"; it is the latter that I am wanting to know more about. How can i keep adding value to a session??? I need to somehow keep storing more values into an array. session_start(); // store session data $_SESSION['tune_name']=$_GET['tune_name']; $_SESSION['tune']=$_GET['tune']; print_r($_SESSION); So this is what i get from the print_r(); Array ( [attach] => Array ( ) [backups-2] => true [dnb] => true [house] => true [tech-house] => true [uk-garage] => true [uk-grime] => true [uk-hip-hop] => true [uncategorized] => true [warehouse] => true [views] => Music/dnb/Gold Dust (Vocal VIP Mix)_DJ Fresh_192.mp3 [tune_name] => Music/dnb/Dj Ss - We Came To Entertain (Sub Zero Remix).mp3 [tune] => Array ( ) ) ok what i need to do is everytime i click it saves that value above but just appends another value to the array so the session can keep getting larger and larger??? Any help please. When I try to add 30 days: Code: [Select] $date = date("Y-m-d"); $date = strtotime(date("Y-m-d", strtotime($date)) . " +30 days"); echo $date; and I echo date I get 1330664400 How do I get it to echo out 3/1/2012? I know the answer lies in the strtotime but I can't figure it out. I know it's a simple problem for most of you... what is the propper way to write Code: [Select] $payrollweek="10"; date('Y-m-d', strtotime("+($payrollweek - 2) week $payrollend") ), "<br />"; its the ("+($payrollweek - 2) that isnt working i think Hi I currently pass a URL to our website as follows: http://website.com/?nid=10 but want to extend this to include a keyword from google as well. For example http://website.com/?nid=10&kw={keyword}. However it may not always have a keyword so if it does not it needs to just use the nid array. This is the current script, how do I go about changing it so that if it just contains a nid and no keyword it will do one search of the array and return the result, and if it does have a nid&keywordod it returns something different. For example if it had nid=1 it would return 0844 000 0300 and if it had nid=1&kw=help it would return 0844 000 0350 Thats what I am looking to achieve. Is this possible and how do I change the array. I have had a little attempt but not sure what I am doing and just got coding errors. <?php $GLOBALS['ct_get_parameter_name'] = 'nid'; $GLOBALS['ct_default_number_id'] = 0; // source_id => phone number $GLOBALS['numbers'] = array( 0 => '0844 000 3000', 1 => '0844 000 0300', 2 => '0844 000 0301', 3 => '0844 000 0302', ); session_start(); if (array_key_exists($GLOBALS['ct_get_parameter_name'], $_REQUEST)) { $_SESSION['ct_source'] = $_REQUEST[$GLOBALS['ct_get_parameter_name']]; } function get_phone_number() { $numbers =& $GLOBALS['numbers']; $default_number_id = $GLOBALS['ct_default_number_id']; if (isset($_SESSION['ct_source'])) { if (array_key_exists($_SESSION['ct_source'], $numbers)) { return $numbers[$_SESSION['ct_source']]; } else { // otherwise return first number return $numbers[$default_number_id]; } } else { // return first number return $numbers[$default_number_id]; } } ?> Many thanks in advance.
