Classe: PorterStemmer - X-Ref

PHP5 Implementation of the Porter Stemmer algorithm. Certain elements
were borrowed from the (broken) implementation by Jon Abernathy.

Usage:

$stem = PorterStemmer::Stem($word);

How easy is that?

PorterStemmer() X-Ref

Regex for matching a vowel

Stem($word) X-Ref

Stems a word. Simple huh?

param: string $word Word to stem
return: string Stemmed word

step1ab($word) X-Ref

Step 1

step1c($word) X-Ref

Step 1c

param: string $word Word to stem

step2($word) X-Ref

Step 2

param: string $word Word to stem

step3($word) X-Ref

Step 3

param: string $word String to stem

step4($word) X-Ref

Step 4

param: string $word Word to stem

step5($word) X-Ref

Step 5

param: string $word Word to stem

replace(&$str, $check, $repl, $m = null) X-Ref

Replaces the first string with the second, at the end of the string. If third
arg is given, then the preceding string must match that m count at least.

param: string $str   String to check
param: string $check Ending to check for
param: string $repl  Replacement string
param: int    $m     Optional minimum number of m() to meet
return: bool          Whether the $check string was at the end

m($str) X-Ref

What, you mean it's not obvious from the name?

m() measures the number of consonant sequences in $str. if c is
a consonant sequence and v a vowel sequence, and <..> indicates arbitrary
presence,

<c><v>       gives 0
<c>vc<v>     gives 1
<c>vcvc<v>   gives 2
<c>vcvcvc<v> gives 3

param: string $str The string to return the m count for
return: int         The m count

doubleConsonant($str) X-Ref

Returns true/false as to whether the given string contains two
of the same consonant next to each other at the end of the string.

param: string $str String to check
return: bool Result

cvc($str) X-Ref

Checks for ending CVC sequence where second C is not W, X or Y

param: string $str String to check
return: bool Result
