utf8_strpos (line 31)

UTF-8 aware alternative to strpos

Find position of first occurrence of a string Note: This will get alot slower if offset is used Note: requires utf8_strlen amd utf8_substr to be loaded

• return: integer position or FALSE on failure
• see: utf8_substr()
• see: utf8_strlen()
• see: http://www.php.net/strpos

• string $str: haystack
• string $needle: needle (you should validate this with utf8_is_valid)
• integer $offset: offset in characters (from left)

utf8_substr (line 120)

UTF-8 aware alternative to substr

Return part of a string given character offset (and optionally length) Note: supports use of negative offsets and lengths but will be slower when doing so

• return: string or FALSE if failure

• string $str
• integer $offset: number of UTF-8 characters offset (from left)
• integer $length: (optional) length in UTF-8 characters from offset
