About in array

Hello,

array(0,1,5,6)

source: 2

How Can I find the grand value than 2 in array (echo 5)

AND

array(1,2,4)

source: 5

If there isn't a value grand than 5, the output can be 1(on the beginnest). How can I find it?

Thank you

It sounds like you want to use 5 as an index, e.g., $x[5] for an array $x. For the latter, you check if count($x) >= 5.

I want 5 because it is the first grand value than 2.
Can you give an example? I am beginner.

Have you read through the PHP manual page that describes what an [man]array[/man] is (and how to use one)?

laserlight did give you an example; you have the numerical index of the array item you want, so use that index inside square brackets.

By "grand value" do you mean the "largest"? You want the first element in the array that is larger than the given value (or the first value in the array if there isn't a larger one)?

sort($array);
foreach($array as $value)
{
    if($value > $given_value) return $value;
}
return $array[0];

Yes, the same.
Thank you very much

I have to run this way?

$array = array(1,3,5,8,9);
$given_value=6;
sort($array);
foreach($array as $value)
{
    if($value > $given_value) return $value;
}
return $array[0];
echo $value;

What Weedpacket was suggesting above is something you'd put in the body of a [man]function[/man] you define. If you're only going to do this in one spot, then a function probably isn't needed. However, you'll have to change the code such that it doesn't use [man]return[/man].

Problem ok,
Thanks

          $numbers = array (1,3,5,6);
          sort($numbers);
          $source = 2;
          $birsonrakigunn = $numbers[0];

      foreach($numbers as $number) {
      if($number > $source) {
      $birsonrakigunn = $number;
      break;
      }
      }

echo $birsonrakigunn;
