Ordering PHP Array by Word Count

[NoLimits]

I am trying to take the contents of a one dimensional php array and sort them in descending order, by the number of words in each string.

eg... here is my current array

array[0] = the dog was lazy
array[1] = the lazy dog
array[3] = wow that dog sure is lazy

I would like it to re-order as follows:

array[0] = wow that dog sure is lazy
array[1] = the dog was lazy
array[2] = the lazy dog

Any assistance, greatly appreciated.

A user-defined sort may be your answer:

function cmp($a, $b) 
{ 
  $a = strlen($a); 
  $b = strlen($b); 
  if ($a == $b) { 
    return 0; 
  } 
  return ($a > $b) ? -1 : 1; 
} 
$array[0] = 'the dog was lazy'; 
$array[1] = 'the lazy dog'; 
$array[3] = 'wow that dog sure is lazy'; 
print_r($array); 
usort [php.net]($array, 'cmp'); 
print_r($array);

coopster, shouldn't that be

str_word_count()

where you used

strlen()

?

by the number of words in each string

I do believe you are correct, RonPK. str_word_count, split, something along those lines. Nice catch!
