PHP - Cant Get Numbers From Variables
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"); } 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 does anyone know how to decode this XML variable value into string values? I also need to know the oposite way: creating variable values into xml. I've tried several code examples but they did filter the requested data.

I have some code which needs to return a single variable from the function and stored as a variable within this page, so it can be echoed later on in the page. I couldn't get it to return as a variable, so i used "return compact();" to return the variable and "extract (myFunction());" to extract it to variables. However, when I turned on php's display errors and error reporting function, I got an error message saying "Warning: extract() [function.extract]: First argument should be an array in /my/web/site/index.php on line 6" (which is where my extract function is). This works fine with passing more than one variables through, is there another way pass one variable from a function to be stored as a variable on the page which called the function? Here is the function: Code: [Select] <?php //This is a list of numeric error codes against their text. this will return the error code as the variable $issue function checkLoginIssue() { //If there is an error code if (isset($_GET["issue"])) { //cycle through the list until the code is reached, return the text and break the switch switch ($_GET["issue"]) { case "1": $issue = '<p class="warning">Please log in to view this page</p>'; break; case "2": $issue = '<p class="warning">Wrong Username or Password</p>'; break; case "3": $issue = '<p class="warning">No user found with those details</p>'; break; } //return the variable in an array with a single value return compact('issue'); } } ?> And here is the code which calls the function: Code: [Select] <?php extract(checkLoginIssue()); ?> 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)" 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 Hello Guys, I have a var for height like $height="67" and want to be able to split that number into, so that I can display 6 feet 7 inches but I have not figured out how to do it.. 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>"; 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"); i have a price i want to add 10%-15% to the base price and that the result will be rounded to 9 in the ones digit place. for example 85 +15%=97.7 $result=99 117+15%=134.55 $result = 139 played with round() and ceil() I have a cards array, and I have this function which will shuffle the cards for me. How can I edit this to 'deal' 12cards (6 & 6) until all the cards are a specific 6 & 6 I pick out? Code: [Select] function ShuffleCards(&$cardsArray, $times) { // Randomizes where to split within center (-3 to +3 from dead center) (MINIMUM 10 CARDS IN DECK) // Splits into two array. Randomizes how many cards from left and how many cards from right (between 1 and 3) // Alternates sides. Continues until both arrays are empty. $arraySize = count($cardsArray); if($arraySize<10) return; $deadCenter = $arraySize/2; for($i=0;$i<$times;$i++) { reset($cardsArray); $cutVariant = rand(-3, 3); $cutLocation = $deadCenter+$cutVariant; $firstArray = array(); $secondArray = array(); for($z=0;$z<$arraySize;$z++) { if($z<$cutLocation) array_push($firstArray, $cardsArray[$z]); else array_push($secondArray, $cardsArray[$z]); } $bottomFirst = rand(0, 1); $cardsArray = array(); while(count($firstArray) && count($secondArray)) { $leftNewCards = array(); $rightNewCards = array(); $leftVariant = rand(1, 3); if($leftVariant>count($firstArray)) $leftVariant = count($firstArray); $rightVariant = rand(1, 3); if($rightVariant>count($secondArray)) $rightVariant = count($secondArray); for($x=0;$x<$leftVariant;$x++) { array_push($leftNewCards, array_shift($firstArray)); } for($y=0;$y<$rightVariant;$y++) { array_push($rightNewCards, array_shift($secondArray)); } if($bottomFirst==0) { $newCardsArray = array_merge($leftNewCards, $rightNewCards); $bottomFirst = 1; } else { $newCardsArray = array_merge($rightNewCards, $leftNewCards); $bottomFirst = 0; } reset($newCardsArray); while(count($newCardsArray)) { array_push($cardsArray, array_shift($newCardsArray)); } } if(count($firstArray)) { while(count($firstArray)) array_push($cardsArray, array_shift($firstArray)); } if(count($secondArray)) { while(count($secondArray)) array_push($cardsArray, array_shift($secondArray)); } } } Hello, Example X = 50 I have been trying to find a way so that I can loop a foreach to insert into a database X and every other number below X unless X already exists. is this possible? -John Hello everyone, i am working on a page that displays news topic and would like to have the page numbers at the bottom of the page as links. You know the usual prev (link) then list couple of pages and then next (link). prev - 1 2 3 4 5... next below is the code i have to count my records on my db and display them. but the problem with this is that it displays all of them. page 1 through 50.

Hey, I have checkbox and with these I am setting an exam. I want the questions to contain numbers. So for each question a number would be displayed. So far I am Only getting the question and the choices to display. <html> <?php session_start(); include '../Database/connection.php'; $Value22 = mysql_real_escape_string(trim($_POST['myselects'])); $_SESSION['myselect23'] = $Value22; //echo $_SESSION['myselect23']; ?> <body> <form action="Staff_Menu.php" method="post"> <?php include '../Database/previous_q.php'; while($info = mysql_fetch_array( $sql )) { echo "{$info['Que_Question']} <br />\n"; echo "<input type=\"checkbox\" name=\"choice1[]\" value=\"{$info['Que_Choice1']}\" /> "; echo "{$info['Que_Choice1']} <br />\n"; echo "<input type=\"checkbox\" name=\"choice2[]\" value=\"{$info['Que_Choice2']}\" /> "; echo "{$info['Que_Choice2']} <br />\n"; echo "<input type=\"checkbox\" name=\"choice3[]\" value=\"{$info['Que_Choice3']}\" /> "; echo "{$info['Que_Choice3']} <br />\n"; echo "<input type=\"checkbox\" name=\"choice4[]\" value=\"{$info['Que_Choice4']}\" /> "; echo "{$info['Que_Choice4']} <br />\n"; } ?> <input type="submit" value="submit"/> </body> </html> </body> </html> Working through some beginner stuff and ive copied some code straight out the textbook, word for word yet it produces: Parse error: syntax error, unexpected T_ECHO, expecting ',' or ';' in C:\wamp\www\PHP Work\StringtoNumbers.php on line 11 <html> <head> <title>Strings Into Numbers</title> </head> <body> <h1>Strings Into Numbers</h1> <ul> <?php $n = "0x237a"; echo "<li>".$n."</li>" echo "<li>".($n * 3)."</li>"; $n2 = "34re5"; echo "<li>".($n2 + 2)."</li>"; $n3 = "boo"; echo "<li>".($n3 + 2)."</li>"; ?> </ul> </body> </html> I need to be able to add all the numbers together collected from the database with mysql_fectch_array Code: [Select] public function gradeQuery(){ $id = $this->idQuery(); $sql = "SELECT*FROM grades WHERE moviesID = '$id'"; $result = mysql_query($sql); $row = mysql_fetch_array($result); $num_rows = mysql_num_rows($result); } 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 $x, would be very greatly appreciated. Thanks in advance. if (preg_match($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? How I can format the number in a string to be displayed as four-digit. I mean transforming 1 to 0001; and 54 to 0054. Hi ..am new to PHP and am using it to solve some mathematical problems which require extensive computation. Following is a code to solve a problem: Code: [Select] <?php $num =1; $n =0; $temp = 0; $count =0; $Final =0; While( $num < [color=orange]1000000)[/color] { $n = $num; while($n >1) { if(( $n % 2) == 0) { $n = $n/2; $temp++; } else { $n =3*$n +1; $temp++; } } If($temp > $count) { $count =$temp; $Final =$num; } $num++; $temp =0; } echo $Final; echo "<BR>"; echo $count; ?> I am running into "Maximum execution time of 30 seconds exceeded" error...its happening coz of the number 1 million...the code wrks fine for 100,1000,10000 and 100000...but breaks down @ 1000000.....is there any way to solve this situation...or PHP is not capable of handling huge numbers? please help...am stuck with this even though am so close to solving the prob. Thanks Abhijeet 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 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! |
