PHP - Range Of Numbers In An Array...

NOTE - Please read the information first as it contains important information to understand the problem.

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)

I wish to return the object in an array with the highest index where its index falls between between integers, and return null should one not exist.

For instance, with the following and a min and max of 10,000 and 15,000, it should return OBJ4, and with a min and max of 15,000 and 20,000 it should return NULL.

Any thoughts?  Thanks

function getObj(int $min, int $max):?OBJ {
    $list=[
        12314=>'OBJ1',
        321=>'OBJ2',
        42142=>'OBJ3',
        14314=>'OBJ4',
        123=>'OBJ5',
        13314=>'OBJ6'
    ];
    return getIt($list, $min, $max);
}

 

$bl = array(); 
$link1 = array_rand($cds); 
$link2 = array_rand($cds); 
$link3 = array_rand($cds); 
$link4 = array_rand($cds); 
$A = 0;
while (!in_array($link1, $bl)){
$link1 = array_rand($cds);
$bl[$A] = $link1;
$A++;
}
while (!in_array($link2, $bl)){
$link2 = array_rand($cds);
$bl[$A] = $link2;
$A++;
}
while (!in_array($link3, $bl)){
$link3 = array_rand($cds);
$bl[$A] = $link3;
$A++;
}
while (!in_array($link4, $cds)){
$link4 = array_rand($cds);
$bl[$A] = $link4;
$A++;
}
echo $link1;
echo $link2;
echo $link3;
echo $link4;

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));
     }
    }
   }

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 ....

Hello all, I am newbie to php programming, any suggestions or advance greatly appreciated.

I can't figure out how to output two array random numbers in ascending order.

<?php

$l_numbers = array(1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27,
 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47);
 
$mega = range(1, 27);


for($i = 0; $i <= 4; $i++)  {


 $random1 = array_rand($l_numbers);
  echo "$random1 \n" ;
}
for($e = 1; $e <= 1; $e++) {

 $random2 = array_rand($mega);
  echo "<p> Mega number is $random2 </p>";
}

echo "Winning numbers are $random1 and mega $random2";

?>

example: Winning numbers are 3,5,10,17,39 and mega 5.

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.

 

 

 

 

Hi,
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 range of categories from 1 to 999

With this is piece of code:

foreach (range(96,204) as $number)
if (Tools::getValue('id_category') == $number)
return;
$this->filterResults();
return $this->display( __FILE__, 'block-center-filter.tpl');

iw managed to avoid display of 'block-center-filter.tpl' in that range but it shows in every other categories.

What i need is opposite... i would like to dont show except in that range...
how to do that?

Why is this not working?
Code: [Select]
$result = mysql_query("SELECT * FROM contacts WHERE type = 'consumer' AND sent BETWEEN '".date("Y-m-d")."' AND '".date("Y-m-d", strtotime("-7 days"))."'")
or die(mysql_error());
$numrows = mysql_num_rows($result);
if($numrows < 0 ){
echo "No records found";
}

The record that is stored in the sent column is like this "2011-11-03 14:42:12", so there is a record in there, but nothing is showing up.

Can anyone see why?

thanks in advance

I am currently working on a date range script and wondering if anybody think of an easier way to do this, doing up to next 8 weeks?  This one starts on a Sunday. I also need to do one starting on a Monday (will figure that one later)

$thisweek = date("Y-m-d");
$week = date('w', strtotime($thisweek));
$date = new DateTime($thisweek);
$firstWeek = $date->modify("-".$week." day")->format("M d");
$endWeek = $date->modify("+6 day")->format("M d");
echo $firstWeek." - ";
echo $endWeek;

$nextweek = date(("Y-m-d"), strtotime("+7 Days"));
$week1 = date('w', strtotime($nextweek));
$date1 = new DateTime($nextweek);
$firstWeek1 = $date1->modify("-".$week1." day")->format("M d");
$endWeek1 = $date1->modify("+6 day")->format("M d");
echo $firstWeek1." - ";
echo $endWeek1;

 

This works if say I do 192.168.0.1 - 192.168.1.254 it will work. However doing 192.168.0.1 - 192.168.1.10 will only generate up to .10 on both IP schemes. I see why, but I cannot figure out a way around this...

Thanks!

$start = explode('.', '192.168.10.1');
$end = explode('.', '192.168.11.10');

/**
 * Final output...
 */
$a = 0;
$b = 0;
$c = 0;
$d = 0;

// First segment
for ($a = $start[0]; $a < 1 + $end[0]; $a++)
{
// Second segment
for ($b = $start[1]; $b < 1 + $end[1]; $b++)
{
// Third segment
for ($c = $start[2]; $c < 1 + $end[2]; $c++)
{
// Fourth segment
for ($d = $start[3]; $d < 1 + $end[3]; $d++)
{
echo "{$a}.{$b}.{$c}.{$d}<br />";
}
}
}
}

I have a simple script that converts an ip range to a readable ip address,

e.g 2147483647 = 127.255.255.255 and it works fine up to this range,
anything after this causes an incorrect ip address.

e.g 2147483648 should be 128.0.0.0 but it outputs 128.0.0.255 and so all ip address after this are incorrect!

code I am using is below;

$rawip_from = '2147483648';

// raw to readable ip
$w1 = (int)($rawip_from / 16777216) % 256;
$x1 = (int)($rawip_from / 65536   ) % 256;
$y1 = (int)($rawip_from / 256     ) % 256;
$z1 = (int)($rawip_from           ) % 256;

$rawip_to = '2147549184';
// raw to readable ip
$w2 = (int)($rawip_to / 16777216) % 256;
$x2 = (int)($rawip_to / 65536   ) % 256;
$y2 = (int)($rawip_to / 256     ) % 256;
$z2 = (int)($rawip_to           ) % 256;

$ip_from = ($w1.'.'.$x1.'.'.$y1.'.'.$z1);
$ip_to = ($w2.'.'.$x2.'.'.$y2.'.'.$z2);

echo "Ip raw range: $rawip_from - $rawip_to<p>Ip range: $ip_from - $ip_to";

/* should output 
Ip raw range: 2147483648 - 2164260863

Ip range: 128.0.0.0 - 128.1.0.0

but it outputs 128.0.0.255 - 128.1.0.255
*/
It always seems to add 255 to the last range instead of the correct value?????
I heard there is a bug in php with integers > 2147483647

if anyone knows of a fix it would be great!!


Thanks...

i have the below code which i wrote this monring, for some reason when i assign $date to fetch data from my database i just get the echo of "You had an Error" yet if i manually assign $date as the following it works:

Code: [Select]
$date = strtotime("2011-09-20");
i have it set exactly the same in the database cus if i echo $date

i get:
Code: [Select]
2011-09-20
whats going on? date in php is a cruel function to play around with..

here is my code:
Code: [Select]
<?php
// Query the DB to fetch all data where member_id matches that set in session
$reminder = mysql_query("SELECT * FROM `reminders` WHERE member_id=$_SESSION[SESS_MEMBER_ID]") or die(mysql_error());
//While Loop the results
while($fetch = mysql_fetch_array( $reminder )) { 
// Start date (TODAY!)
$s_date = strtotime("now"); 
// End Date (+7 days from today)
$e_date = strtotime("+1 week"); 
// Fetches Date stamp from "reminderDate" row in DB
$date = $fetch['reminderDate']; 

// Checks if the date is between 2 ranges set above
if($date > $s_date && $date < $e_date) 

//Echo The Results
{
    echo "<div class='notification error png_bg'><a href='#' class='close'><img src='img/cross_grey_small.png' title='Close this notification' alt='close' /></a><div>Custom Error Notification BOX!</div></div>";
}
else
{
    echo "You had an Error";
//echo $date; // TEST that date outputs datestamp "2011-09-02"
}
//END LOOP
}
?>
