int grapheme_substr ( string $string , int $start [, int $length ] )

Return part of a string

Список параметров

string -

The input string. Must be valid UTF-8.

start -

Start position in default grapheme units. If $start is non-negative, the returned string will start at the $start'th position in $string, counting from zero. If $start is negative, the returned string will start at the $start'th grapheme unit from the end of string.

length -

Length in grapheme units. If $length is given and is positive, the string returned will contain at most $length grapheme units beginning from $start (depending on the length of string). If $length is given and is negative, then that many grapheme units will be omitted from the end of string (after the start position has been calculated when a start is negative). If $start denotes a position beyond this truncation, FALSE will be returned.

Возвращаемые значения
