I wrote this function a long time ago in CGI-perl and then translated (if you can call it that) into
PHP. A little clunky to say the least, but should handle true soundex specs 100%:
// ---begin code---
function MakeSoundEx($stringtomakesoundexof)
{
$temp_Name = $stringtomakesoundexof;
$SoundKey1 = "BPFV";
$SoundKey2 = "CSKGJQXZ";
$SoundKey3 = "DT";
$SoundKey4 = "L";
$SoundKey5 = "MN";
$SoundKey6 = "R";
$SoundKey7 = "AEHIOUWY";
$temp_Name = strtoupper($temp_Name);
$temp_Last = "";
$temp_Soundex = substr($temp_Name, 0, 1);
$n = 1;
for ($i = 0; $i < strlen($SoundKey1); $i++)
{
if ($temp_Soundex == substr($SoundKey1, i - 1, 1))
{
$temp_Last = "1";
}
}
for ($i = 0; $i < strlen($SoundKey2); $i++)
{
if ($temp_Soundex == substr($SoundKey2, i - 1, 1))
{
$temp_Last = "2";
}
}
