I forget where exactly I lifted these from, but they’ve been very useful for some coding projects I’ve been working on silently in the background.

Maths and English

I thought I would share them here. Enjoy and use responsibly.

• Simple Measure of Gobbledygook is actually pretty cool.
• Flesch Reading Ease Score you’ve probably heard of before. It’s another way to “grade” text/content/words.

Maths and english, boys, maths and english…

// Number of words: number of space series or linebreaks + 1
$wc = preg_match_all( '/[ \r]/', preg_replace( '/ +/', ' ', $mynewtext), $tmp );
// Number of syllables: vowels not followed by another vowel. Quite accurate approximation.
$syc = preg_match_all( '/[aeiouy][^aeiouy]/', $mynewtext, $tmp );
// Number of polysyllabic words (>=3 syllables): Vowel, non-spaces, vowel, non-spaces, vowel (or more non-spaces-vowel)
$psyc = preg_match_all( '/[aeiouy]([^ ]*[aeiouy]){2,}/', $mynewtext, $tmp );
// Number of sentences: Number of periods, exclamation marks, question marks and linebreaks
$sec = preg_match_all( '/[.!?\r]/', $mynewtext, $tmp );
// Flesch Reading Ease Score
$fres = 206.835 - 1.015 * ( $wc / $sec ) - 84.6 * ( $syc / $wc );
// Simple Measure of Gobbledygook
$smog = 1.043 * sqrt( $psyc * ( 30 / $sec ) ) + 3.1291;
