I'm having trouble sorting an array. When I do, it empties the array
for some reason. Take the following code:
$data = "bird,dog,cat,dog,,horse,bird,bird,bird,lizard";
$array = explode(",",$data); // Create the array
$array = array_diff($array, array("")); // Drop the empty elements
$array = array_unique($array); // Drop the duplicate elements
$array = array_merge($array); // Reset the array keys
print_r ($array);
Up to here it works great. The resulting output is:
Array ( [0] => bird [1] => dog [2] => cat [3] => horse [4] => lizard )
Then if I do this:
$array = sort($array); // Sorts the array
print_r ($array);
The output is "1". I've tried asort, rsort in the place of sort and
get the same results. I've also tried putting the sort in between the
first 4 steps and that doesn't work either. Obviously I'm doing
something wrong here. I'm using PHP 4.3.4. Any suggestions?
