arrays and strings... a little confusing.

Whats is the difference between [] and {} ? define(NL,"<br>\n"); $str="How do you do?"; echo $str[3].NL; echo $str{3}.NL; $array = array("how","do","you","do?"); echo $array[2].NL; echo $array{2}.NL; this outputs d d you you so there's no difference right? When does a string become an array and vice-versa? if I do $str=(array)$str; then $str[0] will contain "How do you do?" but if I do $array=(string)$array then $array contains the string "Array", so it doesn't work both ways. How does PHP works with this? I come from C where a string and an array of char is exactly the same thing, so this kinda confuses me. ____________________________ .
