metaphone()

Our article is about the PHP function metaphone(), which is used to calculate the metaphone key of a string. Note: This function is deprecated as of PHP 8.0.0. It was historically useful for working with strings in PHP. In this article, we will discuss the syntax and usage of metaphone(), as well as provide some examples.

The metaphone() function is used to calculate the metaphone key of a string. The metaphone key is a phonetic algorithm that approximates the pronunciation of a word or phrase. The syntax of the metaphone() function is as follows:

PHP syntax of metaphone()

string metaphone ( string $str [, int $phonemes = 0 ] )

The function takes two parameters, $str and $phonemes. The $str parameter is the string to be processed, and $phonemes is an optional integer value indicating the maximum number of phonemes to be returned. If the $phonemes parameter is omitted or set to 0, the function will return the full metaphone key.

Here is an example of how to use the metaphone() function:
