/**
* Finds first occurrence of a string within another, case insensitive.
* @param string $haystack The string from which to get the first occurrence.
* @param mixed $needle The string to be found.
* @param bool $before_needle (optional) Determines which portion of $haystack this function returns. The default value is FALSE.
* @param string $encoding (optional) The used internally by this function character encoding. If it is omitted, the platform character set will be used by default.
* @return mixed Returns the portion of $haystack, or FALSE if $needle is not found.
* Notes:
* If $needle is not a string, it is converted to an integer and applied as the ordinal value (codepoint if the encoding is UTF-8) of a character.
* If $before_needle is set to TRUE, the function returns all of $haystack from the beginning to the first occurrence of $needle.
* If $before_needle is set to FALSE, the function returns all of $haystack from the first occurrence of $needle to the end.
* This function is aimed at replacing the functions stristr() and mb_stristr() for human-language strings.
