PHP - Pick Highest Number
Hey,
I have an array which stores a bunch of numbers lets say: Code: [Select] [0] = 1[1] = 6 Now a second array has: Code: [Select] [0] = 5 [1] = 6 What im trying to do - is find the first highest number from the second array that is not found in the first array.Both arrays are sorted already by the way using sort(). What is the best way to do this? Similar TutorialsHello, I need to set a CSS class for the highest number in a MySQL column, and the second highest. So for instance I have a column named scores. I would want the <td> with highest scores to be <td.Winner> and the second highest to be <td. RunnerUp>. I know how to set the css part up, so just need help with creating a function. I did something similar to set the background of table cells based on the text data and that looked like this. function cssfromdate($date) { $class = array('December_January' => 'January', 'March_April' => 'March'); return $class[$date]; } while($row = mysql_fetch_array($result)) { echo "<tr>"; echo "<td>" . $row['last_name'] . "</td>\n"; echo "<td>" . ucwords($row['first_name']) . "</td>\n"; echo "<td class=\"".cssfromdate($row['Class_Date'])."\">".$row['Class_Date']."</td>\n"; echo "</tr>"; } I am hoping I can accomplish what I need to doing something similar. I have five names in an array and also numbers 5,2,1,3 and what i want to do is php to look at the numbers and print out the name that corresponds to the number. so for my example the name it should echo out is 'Lee'
$names = array ("Stan", "John", "Dean", "Sam", "Lee"); here are the five names. The idea is to learn php with making a little fixture list with these five names. The problem i have is to make php read the number and then look up the array for the name that corresponds to the number. I hope this explains what I would like to do?
Hi Guys
I'm a bit stuck on a query and hoping someone can help. I'm sure this has a really simple solution.
Below is a simplified representation of a table and I'm trying to select all of the data but where there are instances of the same postID I want to only select the row with the highest version number.
So for instance in a select all on the table below I would expect to get IDs of 2,3 and 4.
id | postID | version Hi folks, i have a complex problem (for me anyway) but i am sure with your help this can be sorted. Problem number 1: I have a simple while loop, but its only showing 4 results when i know there are 5 I am missing something very simple i know: $sql = ("SELECT * FROM postcode WHERE unid='1'")or die ('<p>There seems to be a problem, please try again soon.</p>'); $result = mysql_query($sql,$con); $row = @mysql_fetch_array($result); $i=0; while ($row = @mysql_fetch_assoc($result)){ echo "newpoints[". $i++ ."] = new Array({$row['lat']}, {$row['long']}, icon0, '{$row['postcodename']}', '{$row['postcodename']}'); \n"; } What am i missing here? Problem number 2: I have a bunch of latitude and longitude codes stored in the database. On each page there will be a varied amount of these codes used, but with a max of 20. I need to find the highest number and the lowest number of each lat and long then come up with a code that is in the middle, the idea of this is to center a map. So for example there will be an array like this: 50.852293 -1.76088 51.252938 -0.76128 51.259583 -0.727168 51.274 -0.837 51.123106 -0.970657 First i need to find the highest number of the first code (51.274) then the lowest number (50.852293) and then the highest number of the second code (-1.76088) then the lowest number (-0.727168) Then work out an inbetween code using the highest and lowest codes for each. Does anyone have a clue how to go about this? I am not the worlds best array technition or mathematician I have a row in a MySQL table called id, which auto-increments. I was wondering if anyone knows a PHP solution to find out what the highest number in the row is? I am thinking perhaps execute a MySQL query that will list the highest number, and then echo the result, like $row[id] in PHP? Hi, I need to write some code for this but unsure where to start. Basically i have a database of say 10 rows. I need to be able to input a number and some sort of fair algorithm will choose one of the rows. The number will be from 6 to 10 numbers long, and will need to pick the same result each time based on that number. Its for a lotto game I'm getting the dreaded " Invalid parameter number: number of bound variables does not match number of tokens" error and I've looked at this for days. Here is what my table looks like:
| id | int(4) | NO | PRI | NULL | auto_increment | | user_id | int(4) | NO | | NULL | | | recipient | varchar(30) | NO | | NULL | | | subject | varchar(25) | YES | | NULL | | | cc_email | varchar(30) | YES | | NULL | | | reply | varchar(20) | YES | | NULL | | | location | varchar(50) | YES | | NULL | | | stationery | varchar(40) | YES | | NULL | | | ink_color | varchar(12) | YES | | NULL | | | fontchosen | varchar(30) | YES | | NULL | | | message | varchar(500) | NO | | NULL | | | attachment | varchar(40) | YES | | NULL | | | messageDate | datetime | YES | | NULL |Here are my params: $params = array( ':user_id' => $userid, ':recipient' => $this->message_vars['recipient'], ':subject' => $this->message_vars['subject'], ':cc_email' => $this->message_vars['cc_email'], ':reply' => $this->message_vars['reply'], ':location' => $this->message_vars['location'], ':stationery' => $this->message_vars['stationery'], ':ink_color' => $this->message_vars['ink_color'], ':fontchosen' => $this->message_vars['fontchosen'], ':message' => $messageInput, ':attachment' => $this->message_vars['attachment'], ':messageDate' => $date );Here is my sql: $sql = "INSERT INTO messages (user_id,recipient, subject, cc_email, reply, location,stationery, ink_color, fontchosen, message,attachment) VALUES( $userid, :recipient, :subject, :cc_email, :reply, :location, :stationery, :ink_color, :fontchosen, $messageInput, :attachment, $date);"; And lastly, here is how I am calling it: $dbh = parent::$dbh; $dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_WARNING); if (empty($dbh)) return false; $stmt = $dbh->prepare($sql); $stmt->execute($params) or die(print_r($stmt->errorInfo(), true)); if (!$stmt) { print_r($dbh->errorInfo()); }I know my userid is valid and and the date is set above (I've echo'd these out to make sure). Since the id is auto_increment, I do not put that in my sql (though I've tried that too), nor in my params (tried that too). What am I missing? I feel certain it is something small, but I have spent days checking commas, semi-colons and spelling. Can anyone see what I'm doing wrong? hey all how would I do this.. I'm guessing I need to go four different SELECT queries I have prices in my DB I need to select the highest price one echo it select the second highest price echo it select third highest echo it then select everything else and echo them I have this so far but i dont know how to get the second, third, ext highest. $result = mysql_query("SELECT * FROM stuff ORDER BY price DESC LIMIT 1"); while($row = mysql_fetch_array($result)) { echo $row['image'] . " " . $row['link']; echo "<br />"; } Hi,
Please can someone point me in the right direction to solving this.
The following code set the postage rate on a basket. It selects the lowest postage assigned to a product and set that as the postage rate.
I now need this to work the opposite way round and select the highest postage rate of the added products.
The postage rates are stored in the database as:
0=0.00
1=4.95
2=7.95
3=12.95
So it looks like somewhere there has been something added that tells it to always give preference to the "0" of any products giving the lowest postage but I'm sure on this....
Thanks.

I am trying to get the $sql(s) to choose and print out the the looking_for in the database. However it is not printing anything. Any ideas of where I am need to fix this. I have tried a few ways with no luck. $sql = mysql_query("SELECT id,gender,looking_for FROM Members"); $nr = mysql_num_rows($sql); $sql2 = mysql_query("SELECT * FROM Members WHERE id='".($_POST['$looking_for'])."' LIMIT $pn, $itemsPerPage"); $outputList = ''; while($row = mysql_fetch_array($sql2)) { $id = $row["id"]; $username = $row["username"]; $firstname = $row["firstname"]; if (!$firstname) { $firstname = $username; } $gender=''; $looking_for=''; (1) I need to remove the lowest and higest values from an array. I need to actually remove the two lowest and two highest. I suppose the best thing would be to sort the array and then use a function that just drops the first and last values (twice). Is this the best way? Which function would drop the lowest / highest values? (2) I then need to get the remaining first and last (highest and lowest) values. $array[0] would get first, and revesing the order and $array[0] again would get the last. Is this the best way? Hi all I have some code that displays the high scores for a game. Unfortunately, if a user has more than 1 high score in the table all scores for that user are displayed. I would like to only display the highest score per user. My Current Code Code: [Select] $sql_query = sprintf("SELECT * FROM `highscores` WHERE `gameID` = '106' ORDER BY `score` DESC"); //store the SQL query in the result variable $result = mysql_query($sql_query); if(mysql_num_rows($result)) { //output as long as there are still available fields while($row = mysql_fetch_row($result)) { echo ("$row[3] Scored :$row[5] <br>"); } } //if no fields exist else { echo "no values in the database"; } mysql_close($con); OutPut User1 300 User1 298 User 2 297 User1 296 User3 295 User2 290 I would like the output to be User1 300 User 2 297 User3 295 Any help is much appreciated I Have the following issue and I spend my whole day looking for it. I have a database with a simple admin where I add/delete values. The database structure is the following: id, zip, email The database is called zipdatabase Here is the mailing part: Code: [Select] //headers $headers = "From: <$Email>"; $headers .= "\r\nBcc: <$Bcc>\r\n\r\n"; // send email $success = mail($EmailTo, $Subject, $Body, $headers);The variable $Bcc must come from the database. I am really ignorant so I only got to a point on how to echo the results I need (and this works): Code: [Select] $query = "SELECT email FROM zipdatabase WHERE zip = '$ZIP'"; $result = mysql_query($query); while($row = mysql_fetch_array($result)) { echo "{$r['email']}, "; } ?> For a zip I get more than one result so when I tried using this Code: [Select] $query = "SELECT email FROM zipdatabase WHERE zip = '$ZIP'"; $result = mysql_query($query); while($row = mysql_fetch_array($result)) { $Bcc = "{$r['email']}, "; } echo "Bcc" ?> It only gives me one result. What I noticed is I have 2 issues: - I can't extract the BCC from the database - I don't know how to add more email addresses to the bcc field, I only managed to add more addresses to the $Emailto like: Code: [Select] $EmailTo = "address1@domain.com, address2@domain.com"; $Bcc = "address3@domain.com"; All these variables are defined by a webform and it works flawlessly except the database problem: Code: [Select] $Name = Trim(stripslashes($_POST['Name'])); $Phone = Trim(stripslashes($_POST['Phone'])); $ZIP = Trim(stripslashes($_POST['ZIP'])); $Email = Trim(stripslashes($_POST['Email'])); $Message = Trim(stripslashes($_POST['Message'])); // validation $validationOK=true; if (!$validationOK) { print "<meta http-equiv=\"refresh\" content=\"0;URL=contacterror.htm\">"; exit; } // prepare email body text $Body = ""; $Body .= "Name: "; $Body .= $Name; $Body .= "\n"; $Body .= "Phone: "; $Body .= $Phone; $Body .= "\n"; $Body .= "ZIP: "; $Body .= $ZIP; $Body .= "\n"; $Body .= "Email: "; $Body .= $Email; $Body .= "\n"; $Body .= "Message: "; $Body .= $Message; $Body .= "\n"; Sorry for my ignorance and hope someone here can help. The webform works perfectly except the bcc from the database part. I am creating a program to simulate the Powerball Lottery game, I have everything working but i forgot to add the Quick Pick Option, having alittle bit of an issue with my "if" statement I believe.

Now my issue is, I don't want 2 numbers of the same Value, EVER. Sometimes it does 2|3|2 which is BAD (for my lottery system) is there anyway I can make it so it never will echo out 2 (OR 3) of the same number? I currently have an array that I've built that dumps like this:
0 => array:11 [▼ "category_code" => "123" "category_name" => "Testing" "category_description" => "This is a test category" 19738 => array:5 [▼ "identifier" => "720368842943" "description" => Test Description One "count" => 4 "details" => array:2 [▼ 0 => array:3 [▼ "detail_code" => "2751" "detail_code2" => "43" "detail_specifier" => "Detail One" ] 1 => array:3 [▼ "detail_code" => "2681" "detail_code2" => "9" "detail_specifier" => "Detail Two" ] ] "prices" => array:1 [▼ "01" => "1129.00" ] ] 19739 => array:5 [▼ "identifier" => "720368844121" "description" => "Test Description Two" "count" => 4 "details" => array:2 [▼ 0 => array:3 [▼ "detail_code" => "2751" "detail_code2" => "43" "detail_specifier" => "Detail One" ] 1 => array:3 [▼ "detail_code" => "2681" "detail_code2" => "9" "detail_specifier" => "Detail Two" ] ] "prices" => array:1 [▼ "01" => "1490.00" ] ] I'm using laravel excel in order to export that as an excel file, but it's not quite working the way I intend When it exports to excel I only get the top level info: 123 | Testing | This is a test category But I want to get that info as a header and then each subsequent product for that category as a row, so with the example above it would look like:
123 | Testing | This is a test category Here's the excel code with the array I'm using, which is dumped above: $allCategoryResult= array(); foreach($prices->categories as $category){ $categoryItem = array(); $categoryItem["category_code"] = $category->category_code; $categoryItem["category_name"] = $category->category_name; $categoryItem["category_desc"] = $category->category_desc; foreach($category->skus as $sku){ $skuItem = array(); $skuItem["identifier"] = $sku->sku_info->identifier; $skuItem["description"] = $sku->sku_info->item->description; $skuItem["count"] = $sku->sku_info->item->item_type->count; $skuItem["details"] = array(); foreach ($sku->sku_info->details as $details) { $detailsItem = array(); $detailsItem["detail_code"] = $details->detail_code; $detailsItem["detail_code2"] = $details->detail_code2; $detailsItem["detail_specifier"] = $details->detail_specifier; $skuItem["details"][] = $detailsItem; } $skuItem["prices"] = get_object_vars($sku->prices); $itemCode = $sku->sku_info->item->item_code; $categoryItem[$itemCode] = $skuItem; } $allCategoryResult[] = $categoryItem; } $name = 'Test Export'; $build = Excel::create($name, function ($excel) use ($allCategoryResult) { $excel->setTitle('Test Export'); $excel->sheet('Test Export', function ($sheet) use ($allCategoryResult) { $sheet->fromArray($allCategoryResult);
I developed this game and I couldn't figure how to make random only on available shot glasses but it would still random with unavailable shot glasses. I simple give up. I plan to share this php once I nailed it down but apparently, not successful. Now, I'm share with you anyway. If you can solve the problem and please let us know! http://pastebin.com/F3N05ExK |
