How i can show one array in each loop? for example with this code i can show random color codes for each loop, but i need to show order by DESC:

$Colors = array('111', '222', '333', '444', '555');

$i = 1;

while($i <= $Limit){
  echo "Color Code:". $Colors[array_rand($Colors)]."<br>";
$i++;
}

and this is my result and problem:

Color Code:333
Color Code:333
Color Code:444
Color Code:111
Color Code:555
Color Code:222
Color Code:111
Color Code:222
Color Code:555
Color Code:222
Color Code:333
Color Code:444

how i can show the result like this:

Color Code:111
Color Code:222
Color Code:333
Color Code:444
Color Code:555
Color Code:111
Color Code:222
Color Code:333
Color Code:444
Color Code:555
Color Code:111
Color Code:222
...

What in the world does this code do? –  Maciej Sz Dec 10 '13 at 20:40
    
You are picking random entries from a sequential array and want to list them sequentially? –  AbraCadaver Dec 10 '13 at 20:41
    
Not Random, sequentially –  Alireza Dec 10 '13 at 20:42
    
You shown us two different arrays of which one is undefined here, and the other one isn't used... –  Maciej Sz Dec 10 '13 at 20:43

The obvious followup question is why are you randomizing them initially then? –  Explosion Pills Dec 10 '13 at 20:43

while($i <= $Limit){
    echo "Color Code:". $input[$i % count($input)]."<br>";
    $i++;
}

Or substitute $input for $Colors depending upon what the variable is actually called.

@MaciejSz you could move count outside the loop; technically more efficient but I don't think it would be noticeable for 20 items. –  Explosion Pills Dec 10 '13 at 20:46
    
Not until two years after, when unnoticeably that array grow to 2M items... I'm just saying: it should be automatic. –  Maciej Sz Dec 10 '13 at 20:50
    
@Explosion Pills thank you my friend –  Alireza Dec 10 '13 at 20:53

@MaciejSz time php -r '$x = array("1", "2", "3", "4", "5"); $i = 0; $limit = 2000000; while ($i <= $limit) { count($x); $i++; }' -- takes about 32 MS on my machine. –  Explosion Pills Dec 10 '13 at 20:54

Php 5.2 - 300ms; PHP 5.4 - 600ms; PHP 5.5 - 1s (!) What do you have there? Like 4 Xeons? –  Maciej Sz Dec 10 '13 at 21:07

<?php
$Colors = array('222', '111', '333', '555', '444');
sort($Colors);

for($i = 0; $i < count($Colors); $i++)
{
   printf("Color code: %s <br />", $Colors[$i]);
}
?>

It's a small static array in a very simplistic example, not sure how thread-safety would really be an issue here. The only problem I see would be if they are pushing values into the array they are iterating over, which they shouldn't be and are not in their question. –  Rob M. Dec 10 '13 at 20:52
    
thank you my friend. –  Alireza Dec 10 '13 at 21:00

This should do the trick!

for($i = 0; $i < sizeof($Colors); $i++){
  echo "Color Code:". $Colors[$i]."<br>";
}
