Hello........

Currently i am struggling with php script....... can any one tell me or guide me how to code Automatically generating random number with in the range of 19 to 90 and the number has to change with in 24 hours time duration.........
It's urgent........

Thanks in advance.....

How would I compare 2 random numbers to rows in a table.  The table has 4 rows and 2 colums.  My table is setup like this: ID hp mp then has just randomly placed numbers from 0 to 5.  So far my script looks like this: I have $new_hp=rand(0,5); $new_mp=rand(0,5).  Then i query the db by $myquery=doquery("select hp,mp from users";  $myrow=mysql_fetch_array($myquery); once this is done would a while statement like while ($myrow = mysql_fetch_array($myquery) to what each line in the table has?  I would then need to compare the random numbers to those entries in the database.  Something like if($myrow[hp] == $new_hp && $myrow[mp] == $new_mp) { ?  But if the if statement isnt true it needs go back choose another random number and run same again and again until the statement is true and that is where im stuck at so any help would be greatly appreciated

Hi,

What I'm trying to do is create a script that generates a random list of cars whenever it is run. I have a list of available cars in a MySQL database. I'm just not sure how to get php to generate a list of, say, 20 cars, that are randomly picked from the cars in the database. I may also want to add other statistics like MPG (also already in the database). Can anyone show me how to do this? And is it possible to format the returned data in a table or div format?

Thanks in advance

Rules →

• There are 9 Columns(C1,C2,C3,C4,C5,C6,C7,C8,C9) [ Max columns will be 9]

• The number of Rows can vary from 3,6,9,12,15,18 (Max). In this case Number of Rows shall be 12

Number of Rows = No of Tickets (Max Allowed 6) x Rows Per Ticket (Max Allowed 3). Thus, Max Rows can be 18

• Each Row is required to have 4 Blank Spaces and 5 Filled with Numbers

• All numbers available in the Column Array have to be utilized

• This configuration of an shall create a matrix of 9 Columns & 12 Rows (3 x 4 Tickets), which is 108 MATRIX BLOCKS where only a maximum of 60 numbers can be filled out of 108 available blocksrandomly with the above conditions being met 100%.

• The numbers in column must be arranged / sorted in ASCENDING ORDER (For coding logic purpose, as soon as the number is assigned to the new MATRIX MAP use array_shift() or unset() the number so as to avoid repetition

Example - Row 1 and Column 1 shall generate a MATRIX BLOCK - R1C1

Row 3 and Column 7 shall generate a MATRIX BLOCK - R3C7

Matrix Block can also be termed as Matrix Cell for your ease (if needed)

MASTER SET OF ARRAY WITH NUMBERS

array( "C1"=> array( 1, 2, 3, 5, 6, 7, 9 ), //7 Numbers "C2"=> array( 13, 14, 15, 17, 18, 19 ), //6 Numbers "C3"=> array( 21, 22, 23, 24, 25, 26, 30 ), //7 Numbers "C4"=> array( 31, 33, 34, 36, 37, 38, 39 ), //7 Numbers "C5"=> array( 41, 42, 46, 47, 48, 49, 50 ), //7 Numbers "C6"=> array( 51, 52, 53, 54, 55, 57, 58 ), //7 Numbers "C7"=> array( 61, 62, 64, 65, 69, 70 ), //6 Numbers "C8"=> array( 71, 74, 75, 76, 77, 78 ), //6 Numbers "C9"=> array( 82, 83, 85, 87, 88, 89, 90 ) //7 Numbers );

The above array has 60 Numbers to be filled out of 108 MATRIX BLOCK / CELL which meets the condition that for a FULL BLOCK containing 4 MINI BLOCKS WITH 3 ROWS (max. allowed) EACH

I have been able to generate this without any issue meeting all the conditions of the Columns

My Allocation Matrix Array will look like

array( "R1"=> array( "C1"=> true, // Means that MATRIX BLOCK R1C1 will be NOT EMPTY "C2"=> false, // Means that MATRIX BLOCK R1C2 will be EMPTY "C3"=> true, "C4"=> false, "C5"=> true, "C6"=> false, "C7"=> true, "C8"=> true, "C9"=> false ), "R2"=> array( "C1"=> false, "C2"=> true, "C3"=> false, "C4"=> true, "C5"=> false, "C6"=> true, "C7"=> true, "C8"=> true, "C9"=> false ), "R3"=> array( "C1"=> true, "C2"=> true, "C3"=> true, "C4"=> true, "C5"=> false, "C6"=> false, "C7"=> false, "C8"=> false, "C9"=> true ), "R4"=> array( "C1"=> true, "C2"=> true, "C3"=> true, "C4"=> false, "C5"=> true, "C6"=> true, "C7"=> false, "C8"=> false, "C9"=> false ), "R5"=> array( "C1"=> false, "C2"=> false, "C3"=> false, "C4"=> false, "C5"=> true, "C6"=> true, "C7"=> true, "C8"=> true, "C9"=> true ), "R6"=> array( "C1"=> true, "C2"=> true, "C3"=> false, "C4"=> true, "C5"=> false, "C6"=> true, "C7"=> false, "C8"=> false, "C9"=> true ), "R7"=> array( "C1"=> false, "C2"=> false, "C3"=> true, "C4"=> false, "C5"=> true, "C6"=> false, "C7"=> true, "C8"=> true, "C9"=> true ), "R8"=> array( "C1"=> true, "C2"=> false, "C3"=> false, "C4"=> true, "C5"=> false, "C6"=> false, "C7"=> true, "C8"=> true, "C9"=> true ), "R9"=> array( "C1"=> true, "C2"=> false, "C3"=> true, "C4"=> false, "C5"=> true, "C6"=> true, "C7"=> false, "C8"=> false, "C9"=> true ), "R10"=> array( "C1"=> false, "C2"=> true, "C3"=> true, "C4"=> true, "C5"=> true, "C6"=> false, "C7"=> true, "C8"=> false, "C9"=> false ), "R11"=> array( "C1"=> false, "C2"=> true, "C3"=> false, "C4"=> true, "C5"=> true, "C6"=> true, "C7"=> false, "C8"=> true, "C9"=> false ), "R12"=> array( "C1"=> true, "C2"=> false, "C3"=> true, "C4"=> true, "C5"=> false, "C6"=> true, "C7"=> false, "C8"=> false, "C9"=> true ) );

In the above array R stands for Row, C for Column, TRUE/FALSE (Boolean) means that if TRUE a Number can be filled in the resulting MATRIX BLOCK / CELL ( Row[Number]Column[Number] ) else if FALSE the MATRIX BLOCK / CELL shall be EMPTY

The result for the above shall be

PROBLEM : 

I am unable to understand what should possibly be the logic & loop used here for creating a MATRIX ALLOCATION MAP as shown above

I have tried while, foreach & for but unable determine the perfect combination which would meet the conditions.

(Tried all of the above with Nested Loops also)

Pretty much I'm trying to generate 4 number's between the min and max of an array but I don't want any duplicates. So it checks if the number exists in a bl array if it does it generates another number, well thats the theory. Doesn't work like that though.

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));
     }
    }
   }

So I already have this below...

$state = array (
    1 => 'Sectional',
    2 => 'Regional',
    3 => 'Semi-state',
    4 => 'State'
);

Can those numbers be a range -- 1-16, 17-32, 33-48 and 49-64 -- without just listing them all?

 

 

Hi I would like to use regex in php for this array :

    $strings = array("words", "test" ,"1=1");

words and test is ok , but I want set 1=1 like $i=$i for any value (just numbers)

2=2 or 10=10 and ....

The Script:

<form method="post" action="<?php echo $_SERVER['PHP_SELF'] ?>">
    <input type="text" name="hashtags" />
    <input type="submit" name="submit" />

</form>
<?php

include("connect.php");

?>
<?php

if(isset($_POST['submit'])){

    $hashtags = explode(", ", $_POST['hashtags']);

    for($i= 0; $i < count($hashtags); $i++){

        $tqs = "SELECT `id` FROM `hashtags_two` WHERE `hashtags` = '" . $hashtags[$i] . "'";
        $tqr = mysqli_query($dbc, $tqs) or die(mysqli_error($dbc));

    }

    $fetch_array = array();
    while($row = mysqli_fetch_array($tqr)){
        $fetch_array[] = $row['id'];
    }

}

Hey, sorry for these fundamental array questions lately, I am not going to ask much more when it comes to this.   The hashtags come from the submit form (separated by commas) and get stored inside an array with the "explode()" function. The script should select the ID numbers of the hashtags from the table.   With the script above only the last row gets inserted into $fetch_array inside the while loop.   When the $fetch_array variable is printed on screen then only one ID number can be seen inside the array:

Array ( [0] => 24 ) 

How can I have the other ID numbers too?

Hello,   I am fairly new to PHP and I found some php code to print an array of numbers that create a combination - however, its slams all the numbers together without a space or a comma separator.   How can I separate the numbers in this array with the given code?  Ive attached a photo of the code.

 

 

 

 

I dont know how to word this really. what I want to do is

Code: [Select]

$Var[] = 3;
$Var[] = 6;
$Var[] = 2;
$Var[] = 17;

for($i=0; $i!=count($Var); $i++)
{
echo "#$i: ".$Var[$i]."\n";
}



I know I might be able to use rand() but I need it to echo ALL of the variables in the array in a random order, I know if I use count to find out how many variables there are that it would echo them 4 times randomly but might echo the same variable 2 times making it to where it only echos 3 different varables, if I am being confusing please let me know, I just want to get this resolved, thanks!

Hey guys does anyone know how i would go about generating a random word from an array?

For example:

$words = array("[apple]","[banana]","[kiwi]");

how would i have php choose one of these words and then spit it out?

Thanks!!!

I have it to where it groups two parts of the Array randomly but I need to make it where it won't pair the same together, or if it has already been paired with a team then use another team. Each value of the array can only be used once.

Here is my code
shuffle($teamname);

$loopCount = $games;

for ($i = 0; $i < $loopCount; $i++) {
    $player1 = array_pop($teamname);
    $player2 = array_pop($teamname);
if(is_null($player1))
{
echo 'Not enough different teams to create '.$games.' games';
break;
}
    // output to screen
    echo "Team: " . $player1 . " Vs Team: " . $player2 . "<br />"; 

}
}

Hi guys!

i got this code:
Code: [Select]
<?
$x = "abcde";

str_split($x);
for ($k=0; $k<=119; $k++){
$ax = array($x[0],$x[1],$x[2],$x[3],$x[4]);
shuffle($ax);
    $text = implode("", $ax) . "";
echo $text;
echo "<br />";
}
?>
if you test it you see that it is working but giving me allot of duplicates results!

there is a way to ignore duplicaes while it is runing?

thanx.
