Text_Statistics Description

Text_Statistics allows for computation of readability indexes for text documents.

Text_Statistics calculates some basic readability metrics on a block of text. The number of words, the number of sentences, and the number of total syllables is counted. These statistics can be used to calculate the Flesch score for a sentence, which is a number (usually between 0 and 100) that represents the readability of the text. A basic breakdown of scores is:

<?php
  require 'Text/Statistics.php';
  $block = new Text_Statistics($sometext);
  $block->flesch; // returns flesch score for $sometext
?>

see the unit tests for additional examples.

Text_Word calculates the number of syllables in a word, based off of the number of contiguous vowel groupings in the word and applying matches to detect special cases.

Example 57-2. Example numSyllables() <?php require_once 'Text/Word.php' $word = new Text_Word('word'); $word->numSyllables(); // returns 1 ?>
