The simplicity of the rules got me thinking: how hard would it be to write a program to check if a poem stanza is ottava rima? In this article, we will write a simple ottava rima detector in PHP.

His code takes in the content and performs a few checks, one simple (length) and two custom - "is_iambic_pentameter" and "is_abababcc_rhyme". The code for these two checks are included in the post as well that, in turn, use some other functions to count syllables and vowels and use Arpabet phonetic transcription and monophthongs/diphthongs to detect iambic pentameter and rhyme.
