what i want to do is something like memory game, but I keep cannot get the same number with the out put
$numbers = range(1, 15);
shuffle($numbers);
foreach($numbers as $key){

break;
}
now the out put will be something like this
4 2 3 3
1 5 3 6

so like this i can get the match in 2 same number
any idea how to do it?

Answer 1

Your question is a bit confusing and vague. I extrapolate that you want to shuffle and display an array of numbers, two of each, in random order. To do that:
<?php
$numbers = range(1, 5);
$numbers = array_merge($numbers, $numbers);
shuffle($numbers);
echo implode(' ', $numbers);
This outputs, for instance, 3 5 1 5 1 2 3 4 2 4.
The array_rand() call in the foreach in your code makes absolutely no sense. If the above isn't what you wanted, please revise your question to be clearer.

Answer 2

First you have to do an array with couple values
// Generate array with values from 1 to 8
$arNumbers = range(1, 8);
// Duplicate the array so get copy of each number
$arNumbers = array_merge($arNumbers, $arNumbers);
// Shuffle the array
shuffle($arNumbers);
// And now display them
foreach($arNumbers as $nNumber)
{
// Do some business
}
Hope it helps :)

Try this. It is a simple way.
$numbers=range(1, 15);
//Get 4 unique random keys from $numbers array.
$rand_keys = array_rand($numbers, 4);
//print out the random numbers using the
//random keys.
foreach ($rand_keys as $k=>$i) {
echo $numbers[$i]." ";
}
Hope this will helps you...

Answer 4

If I get you correctly, you can achieve what you want to do with the following:
// make sure these are even numbers
$rows = 4;
$cols = 4;
$set = range(1, ($rows * $cols) / 2);
$numbers = array_merge($set, $set);
shuffle($numbers);
foreach (array_chunk($numbers, $cols) as $row) {
foreach ($row as $col) {
printf('%-5d', $col);
}
echo "\n";
}
Outputs:
3 7 2 1
4 6 8 5
6 3 8 4
2 5 7 1

Answer 5

Do something like:
$numbers = range(1, 15);
shuffle($numbers);
$used_numbers = array();
foreach($numbers as $key){
$this_number = $numbers[array_rand($numbers)];
$used_numbers[] = $this_number;
echo $this_number;
break;
}
$_SESSION['numbers'] = $used_numbers;
Then you can use the $_SESSION to access the numbers on another page (after reload perhaps), or use the same $used_numbers array to access them.
If you try:
$numbers = range(1, 15);
shuffle($numbers);
$used_numbers = array();
foreach($numbers as $key){
$this_number = $numbers[array_rand($numbers)];
$used_numbers[] = $this_number;
echo $this_number;
break;
}
echo '<br />';
foreach($used_numbers AS $number) {
echo $number;
}
You will see it returns the same number.
