Re: [PHP] ksort by value

[John Taylor-Johnston]

           <?php
           ...
           $words = preg_split('/[[:space:]]+/',$mynewstring);
           foreach ($words as $word) {
                 $freq[$word]++;
           }

           ksort($freq);
           print_r ($freq);
           ?>


   Sort does not work seamlessly. I have my key and
   sort($freq);
   print_r ($freq);
   looks like:

   Array
   (
        ...
        [1000] => 172
        [1001] => 176
        [1002] => 179
        [1003] => 441
   )

   This is what I want:

   Array
   (
        ...
        [and] => 172
        [of] => 176
        [to] => 179
        [the] => 441

   )


http://php.net/manual/en/array.sorting.php is pretty clear. But my 
problem is that sort ($freq) destroyed my key.
