soundex
(PHP 4, PHP 5)
soundex — Calculate the soundex key of a string
Description
string soundex
( string $str
)
Soundex keys have the property that words pronounced similarly
produce the same soundex key, and can thus be used to simplify
searches in databases where you know the pronunciation but not
the spelling. This soundex function returns a string 4 characters
long, starting with a letter.
This particular soundex function is one described by Donald Knuth
in "The Art Of Computer Programming, vol. 3: Sorting And
Searching", Addison-Wesley (1973), pp. 391-392.
Parameters
-
str
-
The input string.
