metaphone - Calculate the metaphone key of a string

SYNOPSIS

       string metaphone (string  $str, [int  $phonemes])

DESCRIPTION

	Calculates the metaphone key of $str.

	Similar  to soundex(3) metaphone creates the same key for similar sounding words. It's more accurate than soundex(3) as it knows the basic
       rules of English pronunciation. The metaphone generated keys are of variable length.

	Metaphone was developed by Lawrence Philips <lphilips at verity dot com>. It is described in ["Practical Algorithms for Programmers", Bin-
       stock & Rex, Addison Wesley, 1995].

PARAMETERS

	      o $str
		- The input string.

	      o $phonemes
		-  This parameter restricts the returned metaphone key to $phonemes characters in length. The default value of 0 means no restric-
		tion.

RETURN VALUES

	Returns the metaphone key as a string, or FALSE on failure.

EXAMPLES

       Example #1

	      metaphone(3) basic example

	      <?php
	      var_dump(metaphone('programming'));
	      var_dump(metaphone('programmer'));
	      ?>

	      The above example will output something similar to:

	      string(7) "PRKRMNK"
	      string(6) "PRKRMR"

       Example #2

	      Using the $phonemes parameter

	      <?php
	      var_dump(metaphone('programming', 5));
	      var_dump(metaphone('programmer', 5));
	      ?>

	      The above example will output something similar to:

	      string(5) "PRKRM"
	      string(5) "PRKRM"

NAME

       htfuzzy - fuzzy command-line search utility for the ht://Dig search engine

SYNOPSIS

       htfuzzy [-c configfile] [-v] algorithm [options]

DESCRIPTION

       Description to follow here

OPTIONS

       -c configfile
	      Use the specified configfile instead of the default.

       -v     Verbose mode , -vvv
	       etc ). Specifying more than two v's is probably only useful for debugging purposes.

Supported Algorithms
       Different algoritms are supported for searching:
	      soundex  Creates	 a  slightly modified soundex key database. Differences with the standard soundex algorithm are: Keys are 6 digits
	      and the first letter is also encoded.	   metaphone Creates a metaphone key database. This algorithm is more specific to English,
	      but  will  get  fewer  "weird" matches than the soundex algorithm.

	      accents (No description of the algorithm at the moment)

	      endings Creates  two  databases  which  can  be  used  to match common word endings. The creation of these databases requires a list
	      of affix rules and a dictionary which uses those affix rules. The format of the affix  rules and	dictionary   files  are  the  ones
	      used  by	the  ispell program. Included with the distribution are the affix rules for English and a fairly small English dictionary.
	      Other languages can be supported	by  getting  the appropriate affix rules and dictionaries. These are available for many languages;
	      check the ispell distribu- tion for more details.

	      synonyms	Creates a database of synonyms for words. It reads a text database of synonyms and creates a  database	that htsearch  can
	      then use. Each line of the text database consists of words where the first word will have the other words on that line as synonyms.

Notes on searching
       Please consult specialised literature to find out how the different algorithms work or simply try another
	      search stragegy you do not get the intended search results.
