cada una de tamaño <parameter>length</parameter>, a excepción

<function>str_split</function> realizará la división a nivel de bits,

en lugar de a nivel de caracteres al utilizarse con un string codificado en multibytes.

<function>mb_str_split</function> puede ser utilizado para dividir el string en puntos de código.

<function>grapheme_str_split</function> puede ser utilizado para dividir el string en clusters de grafemas.
