hashing and indexing

[spwpreston]

hello,

i am trying to count all of the words in a string, and am trying to
determine the best data structure for this.

i would like to be able to do something like

$arr_text = explode(" ", $text);

then, i want to count each unique word in $arr_text

i tried using the words as the array offsets, and of course i found
that this is illegal.

is there a php data structure which can accomplish this for me?

something like python's dictionary data structure would be perfect.

thank you so much for reading.

Hello --

Fortunately, there is a function that was designed for this purpose:
str_word_count. So you might do something like this:

$text = 'Some string of random words';
$words = str_word_count($text, 1);
$unique_words = array_unique($words);
$number_unique_words = count($unique_words);
print $number_unique_words;

I hope this helps.

Following on from 's message. . .

See array_count_values() in the manual. I Believe this is exactly what
you're looking for.
