Introduction
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:
|
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
?>
