I have a php script where i load pageloads into an array and i want a way to sort them from biggest to smallest. using normal reverse sort puts 9 above 500 and only does it by the first number. the only one that accurately sorts numbers is natsort or natural sort. but the problem is it ranks from smallest to greatest and i want from greatest to smallest. any way to do this? thanks guys.

I think I'm missing something. What do you mean by 'it only takes the first number'. Can you provide a sample input and the expected output? If you call rsort with input:

1,4,2,9,6,3,5

you should get back

9,6,5,4,3,2,1

PHP Code:

$foo = array(1,4,2,9,6,3,5);
rsort($foo);
print_r($foo); 


will output

Array
(
    [0] => 9
    [1] => 6
    [2] => 5
    [3] => 4
    [4] => 3
    [5] => 2
    [6] => 1
)

Edit:
I think I understand what's going on now. Its trying to sort the input as strings rather than integers. Lexicographically, 9 would be before 500 if you make the assumption they are strings, not numbers. Make sure you cast your input as integers.

Thats weird i tried it in a simple script with nothing else and it worked. but when i try it with my array built with combining text files it doesn't work:
Before Sort:

Array ( [0] => 60 ~http://futuregamespc.com/demo/3d_racing.php~3d Racing~ [1] => 55 ~http://futuregamespc.com/demo/6_differences.php~6 Differences~ [2] => 284 ~http://futuregamespc.com/demo/countertest.php~Untitled 1~ [3] => 2 ~http://futuregamespc.com/demo/games.php~~ )

After Sort:

Array ( [0] => 60 ~http://futuregamespc.com/demo/3d_racing.php~3d Racing~ [1] => 55 ~http://futuregamespc.com/demo/6_differences.php~6 Differences~ [2] => 284 ~http://futuregamespc.com/demo/countertest.php~Untitled 1~ [3] => 2 ~http://futuregamespc.com/demo/games.php~~ )

php to sort it:

PHP Code:

$directory = "/mnt/w0210/d28/s25/b02a8bb2/www/counters/demo/";
//Directory is set;

$directory = (!strstr($directory,"*") || $directory =="./" ) ? $directory."*" : $directory;
//Checks if the wildcard operator is present, and if not it adds it by default at the end;

$files = glob($directory);
//Yes, it was that easy to get all the files;
$size=sizeof($files);
for($i=0;$i<sizeof($files) ; $i++){
  //Loop through the files and adds to array;
$fp = fopen($files[$i],"r");
$contents[$i]=fgets($fp,999);
fclose($fp);
}
print_r ($contents); // print unsorted
rsort($contents); 
print_r ($contents); //print sorted
$imploded = implode(" ", $contents); //get rid of spaces
$newcontent=explode("~", $imploded); // sort into chucks so i can display the data.
print_r ($newcontent); 


The problem is that

60 ~http://futuregamespc.com/demo/3d_racing.php~3d Racing~

is a string (along with every other element in the array). It is a string that happens to begin with a number, but still a string.

What you need to do is use usort and write a custom comparison function that separates the integer from the rest of the string, then uses that to compare. Fortunately, because of the way casting works in PHP, all you have to do is cast each element to an int. For example:

PHP Code:

function cmp($a, $b)
{
    $a = (int) $a;
    $b = (int) $b;

    if($a > $b)
        return -1;
    if($b > $a)
        return 1;

    return 0;
}

$foo = array('10 flskj', '3 kdslfj', '1 sfj', '93 dslkfj');

usort($foo, 'cmp');

print_r($foo); 


will output:

Array
(
    [0] => 93 dslkfj
    [1] => 10 flskj
    [2] => 3 kdslfj
    [3] => 1 sfj
)

Oh! Thank you so much! That makes complete sense. Didn't realize that php sorts them differently by what type of variable they are or even think of that possibility. Thank you so much! Its working now
