#31188 [NEW]: metaphone function returns incorrect results

From: travis at dreamsage dot com Operating system: Windows XP (linux untested) PHP version: 4.3.9 PHP Bug Type: Pspell related Bug description: metaphone function returns incorrect results Description: ------------ Hello and thanks for taking the time to read this. You guys (and gals) are really appriciated. This bug has to do with the metaphone function. This function turns a word into string that represents the sound of the word. I was recently required to write a VB version of this function because none existed and so I translated the original Basic version of this function written around 1990. http://aspell.net/metaphone/metaphone-kuhn.txt I wanted to check my code so I compared about 10,000 words produced by my VB code to the output of PHP and I found 4 bugs in your code. The output of the PHP function does not match what the output of the above algotythm states. 1: Words with GH 2: words with MB. The B is silent at the end of a word "dumb" but not in the middle "camber" 3: words with GN 4 words with CIA Thanks Travis Apple Reproduce code: --------------- . Expected result: ---------------- .
