PHP - Pick The Middle 5 Numbers
Hi guys,
I need to pick the middle five numbers from a range of numbers example $lowest number = 0; // this will allways be 0 $highest_number = 10; // this can very from 1 to 10000 $selected_number = 5; // this can also very but it will allways be between 0 and highest number the middles numbers from the above 3 varuables should be 3 4 5 6 7 --- the $selected_number number allways needs to be the middle number // some of the issue we need to watch out for is, if hughest number is 4 then it should just go 1 2 3 4 Thank you guys Similar TutorialsHi, 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 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?
I am not getting any error messages as I just think the codes are wrong. 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=''; 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? 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. My confusion is whether it should be a nested "if", or should it be it's own entity? Here's what i have so far: Code: [Select] <?php $intGrandPize = 10000000; $intRegCount = 5; $intMaxReg = 59; $intMaxPB = 39; //$quick = rand(1, 59); //$quickPB = rand(1, 49); if (isset($_POST['Quick Pick'])){ if (count($_POST)>0) { $aryPick = array(); $intPower = 0; for($t=1;$t<=$intRegCount;$t++) { if (isset($_POST['num'.$t])) { $intPick = (int)$_POST['num'.$t]; if ($intPick > 0 && $intPick <= $intMaxReg && !in_array($intPick,$aryPick)) { $aryPick[] = $intPick; } } } if (isset($_POST['Power']) && (int)$_POST['Power'] > 0 && $_POST['Power'] <= $intMaxPB) { $intPower = (int)$_POST['Power']; } if (count($aryPick) < 5 || $intPower == 0) { echo "<font color='red'>'*Five unique numbers and a PowerBall selection are Required*'</font>";; } else { // Have valid numbers... sort($aryPick); // For if you are going to display them, they will be in order... // Pick your winners $aryAllBalls = range(1,$intMaxReg); // array of numbers 1 - 59 shuffle($aryAllBalls); // Randomize their order $aryAllBalls = array_chunk($aryAllBalls,$intRegCount); // The above breaks up into an array with 5 numbers each // [0] contains the first 5 balls of all balls randomized, these are what are "picked" $aryPickedBalls = $aryAllBalls[0]; sort($aryPickedBalls); // Sort them for display $intPowerBall = rand(1,$intMaxPB); echo "YOUR WINNING NUMBERS A <br>",implode(' ',$aryPickedBalls),' PB: ',$intPowerBall,"<br>\n<br>\n"; echo "You Picked: "; foreach($aryPick as $key=>$val) { if (in_array($val,$aryPickedBalls)) { echo '<strong>',$val,'</strong> '; } else { echo $val,' '; unset($aryPick[$key]); // Remove it since it didn't match } } $bMatchPB = ($intPower == $intPowerBall); // Set here since checked in 3 places... if ($bMatchPB) { echo 'PB: <strong>',$intPower,"</strong><br>\n<br>\n"; } else { echo 'PB: '.$intPower,"<br>\n<br>\n"; } // At this point, $aryPick will only contain matching numbers... $intMatches = count($aryPick); echo 'You matched '.$intMatches,' numbers and did '; if (!$bMatchPB) { echo 'not '; } echo "match the PowerBall number.<br><br>\n\n"; // HERE YOU WOULD DO SOMETHING TO SAY HOW MUCH THEY WON if ($intMatches>=3 || $bMatchPB) { $intWinnings = 0; switch ($intMatches) { case 0: if ($bMatchPB) { $intWinnings = 3; } break; case 1: if ($bMatchPB) { $intWinnings = 4; } break; case 2: if ($bMatchPB) { $intWinnings = 7; } break; case 3: if ($bMatchPB) { $intWinnings = 100; } else { $intWinnings = 7; } break; case 4: if ($bMatchPB) { $intWinnings = 10000; } else { $intWinnings = 100; } break; case 5: if ($bMatchPB) { $intWinnings = $intGrandPize; } else { $intWinnings = 200000; } break; default: echo "ERROR: Winning Combination not defined in systen!!!<br>\n"; } echo "<strong>YOU ARE A WINNER!!!!</strong><br>\n"; echo 'You Won: $'.number_format($intWinnings,0),"<br>\n"; } else { echo "Sorry, you didn't win. Try again!<br>\n"; } } // END: if (had valid numbers picked) } // END: There was data posted (ie. Form submitted) ?> Code: [Select] function choose_numbers($number,$max) { global $ibforums,$std; srand( (double)microtime() * 1000000 ); $array = array(); $i = 0; while($i!=$number) { $array[] = mt_rand(1,$max); $i++; } $c = count($array); while($c != $number) { $array[] = mt_rand(1,$max); $c = count($array); if($c == $number) { $array = array_unique($array); $c = count($array); } } return $array; } $newnumbers = $this->choose_numbers(3,36); echo "{$newnumbers['0']}|{$newnumbers['1']}|{$newnumbers['2']}"; This echo's out my lottery balls 0|32|22 or technically RANDNuMbER|RANDNUMBER|RANDNUMBER up to 36 is the highest number. 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 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 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 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 creating a ticketing system and i need some assistance. The code directly below displays the database records and the delete works fine. The edit however isn't picking the values in the various fields.

How to solve by using observer? Edited August 12, 2019 by aveevaI have a file named example.xml I want to know how to write to the 3rd line on this file? What function to use? I want to be able to write to this xml file right after the <sitemapindex xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"> tag. Please someone tell me how? Much appreciated. Code: [Select] <?xml version="1.0" encoding="UTF-8"?> <sitemapindex xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"> <sitemap> <loc>http://www.example.com/sitemap1.xml.gz</loc> <lastmod>2004-10-01T18:23:17+00:00</lastmod> </sitemap> <sitemap> <loc>http://www.example.com/sitemap2.xml.gz</loc> <lastmod>2005-01-01</lastmod> </sitemap> </sitemapindex> Is this the correct syntax to check for an optional Middle Initial... Quote if (preg_match('/^?[A-Z]$/i', $_POST['middleInitial'])){ Thanks, Debbie HELP!!! PLEASE!!! Here's what's happening: I have a string much like this one: Code: [Select] $str = "84,390961CPK_100,'Pink Coloured Cord',15,'390961CPK_100',1"; I need to insert apostrophes around the first instance of 390961CPK_100 so it reads '390961CPK_100' and not simply 390961CPK_100. To do this I have made the string into an array as follows: Code: [Select] $str_array = str_split($str); Now I need to insert quotes into the array of characters, then convert the whole mess into back into a string. I can't go by hard coded index numbers, because all of the text in this string is variable in length, so I have to go by the first and second positions of the commas. I have no idea how to do this, and it needs to be done yesterday! Mucho Gracias to anyone who can help me with this. I looked through all the array functions in the manual, but didn't see what I needed (might have just missed it) Is there a way to stick a value into the middle of an array, without writing over the current value? I would need it to just push the rest back 1. Hope that explains what Im looking for! Thanks in advance I need some advice on how to debug in the middle of other code I want to change a file. This file gives no direct output and contain a load of functions What I want to do is make changes to this file and trace values - how do I do this? - Can I give a popup with a message? - Could I write values to a file? (Can I write to some sort of standard log file? Maybe the error log file?) - Or is it possible to still give output to a web page, even though the code is not part of the code that outputs to the browser? What's the standard practice of debugging as mentioned above? Any help would be really appreciated Thanks! OM I am trying to figure out how to have an if statement in the middle of strings I am trying to concatenate. I have a from that has a address1 and address2, where address2 often does not exist. So I want to only add that line if there is actually content. I was trying something like the following, but that is giving me an error. I am pretty new to php, so I can't seem figure it out. Any help would be greatly appreciated. Code: [Select] "<p><strong>Address 1: </strong><br>" . $address1 . "<br>" if ( isset($address2) ) { echo . $address2 . "<br>" } . $city . ", " . $state . " " . $zip . "</p>" I'm calling the image page via ajax. Depending on what date is selected will be written to the image. However I'm getting header error on my main page. What would be the proper way to display the generated image to the user? Can I do it without saving it?
// FETCH IMAGE & WRITE TEXT
$img = imagecreatefromjpeg('balloon.jpg');
$white = imagecolorallocate($img, 255, 255, 255);
$txt = "Hello World";
$font = "C:\Windows\Fonts\arial.ttf";
imagettftext($img, 24, 0, 5, 24, $white, $font, $txt);

Hi All, I am working on system where i am storing column names in one table of database. To retrieve value of columns with separation of comma (exp. clol1, col2,col3..). for this i am using one function which i am calling middle of mysql query. but i am not getting fetch result over there. Below is the function i have to fetch column names. Code: [Select] function retrieve_columns() { $brand_id = $_SESSION['SESS_PRODUCT_CODE']; global $columnlist; $columns_query= "Select column_name from columns_list_to_display where brand_id=$brand_id"; $result=mysql_query($columns_query); $row_num=mysql_num_rows($result); $i=0; while ($row = mysql_fetch_array($result)) { $columnlist = ""; $i++; if($i != $row_num) { echo $row['column_name'].", "; } else { echo $row['column_name'].""; } } } I am writting query like as below: Code: [Select] $query = "SELECT " . $columnlist . "FROM $userlead_table LEFT JOIN notes ON $userlead_table.id = notes.leads_id LEFT JOIN lead_status ON $userlead_table.status = lead_status.status_code WHERE ((Date(a.submitted)>='$datefrom' AND Date(a.submitted)<='$dateto')) ORDER BY a.submitted DESC"; Please let me know where i am doing wrong. Hope one of this forum member would have proper solution for it. Thanks in advance. Regards, Jitendra |
