how to sort an array? sort() does not work?

[carsten888]

I'm just trying to sort an array.

$arr = array(13, 55, 25);
print_r($arr);
//returns:
//Array ( [0] => 13 [1] => 55 [2] => 25 ) 

$arr = sort($arr);
print_r($arr);
//returns:
//1

I tried to make a new array out of the object:

$new_arr = array();
foreach($arr as $item){
$new_arr[] = $item;
}

which just gives this error :
Invalid argument supplied for foreach()


What am I overlooking here?

You get a 1 because the function sort() returns true. Do this.

<?php
header("content-type:text/html");
$backward = $arr = array(25, 55, 18, 1);
sort($arr);
rsort($backward);
echo "<br>Sorted Backward:<br>";
print_r($backward);
echo "<br>Sorted Forward:<br>";
print_r($arr);
?>

Works on strings too.
