PHP - Adding Numbers

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 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>";

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));
     }
    }
   }

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");

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!

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");
}

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.

i have a price i want to add 10%-15% to the base price and that the result

Hi Guys   I have a regex conundrum that at first I thought would be very easy but then appears to be quite hard :/   I want to match a string with a regex where the regex can only pass if it contains letters and numbers (nothing else) and it has to contain at least one of each.   I've been trying out lookaheads but just can't get it right.     Any help is appreciated.    Drongo
