Question

In php I need to Load a file and get all of the words and echo the word and the number of times each word shows up in the text, (I also need them to show up in descending or

Here's an example:

$text = "A very nice únÌcÕdë text. Something nice to think about if you're into Unicode.";

// $words = str_word_count($text, 1); // use this function if you only want ASCII
$words = utf8_str_word_count($text, 1); // use this function if you care about i18n

$frequency = array_count_values($words);

arsort($frequency);

echo '
';
print_r($frequency);
echo '
';

The output:

Array
(
    [nice] => 2
    [if] => 1
    [about] => 1
    [you're] => 1
    [into] => 1
    [Unicode] => 1
    [think] => 1
    [to] => 1
    [very] => 1
    [únÌcÕdë] => 1
    [text] => 1
    [Something] => 1
    [A] => 1
)

And the utf8_str_word_count() function, if you need it:

function utf8_str_word_count($string, $format = 0, $charlist = null)
{
    $result = array();

    if (preg_match_all('~[\p{L}\p{Mn}\p{Pd}\'\x{2019}' . preg_quote($charlist, '~') . ']+~u', $string, $result) > 0)
    {
        if (array_key_exists(0, $result) === true)
        {
            $result = $result[0];
        }
    }

    if ($format == 0)
    {
        $result = count($result);
    }

    return $result;
}
