The default length is 1, meaning every chunk will be one byte in size. &reftitle.errors; If length is less than 1, a ValueError will be thrown. &reftitle.changelog; &Version; &Description; 8.2.0 If string is empty an empty &array; is now returned. Previously an &array; containing a single empty string was returned. 8.0.0 If length is less than 1, a ValueError will be thrown now; previously, an error of level E_WARNING has been raised instead, and the function returned &false;. &reftitle.examples; ]]> &example.outputs; H [1] => e [2] => l [3] => l [4] => o [5] => [6] => F [7] => r [8] => i [9] => e [10] => n [11] => d ) Array ( [0] => Hel [1] => lo [2] => Fri [3] => end ) ]]> &reftitle.notes; str_split will split into bytes, rather than characters when dealing with a multi-byte encoded string. mb_str_split can be used to split the string into code points. grapheme_str_split can be used to split the string into grapheme clusters. &reftitle.seealso; mb_str_split grapheme_str_split chunk_split preg_split explode count_chars str_word_count for
