Introduction
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:
| 90 to 100 | 5th grade |
| 80 to 90 | 6th grade |
| 70 to 80 | 7th grade |
| 60 to 70 | 8th and 9th grade |
| 50 to 60 | 10th to 12th grade (high school) |
| 30 to 50 | college |
| 0 to 30 | college graduate |

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