PHP metaphone() Function

The metaphone() function calculates the metaphone key for a string. A metaphone key describes how a string of letters sounds when spoken by an English speaker. This function can be used in spelling applications and creates identical keys for similarly-sounding words. The length of the metaphone keys generated varies.

• string - (Required) Specify the string to check.
