According to PHP official manual It is used to converts a string to an array.If the optional split_length parameter is specified, the returned array will be broken down into chunks with each being split_length in length, otherwise each chunk will be one character in length. FALSE is returned if split_length is less than 1.If the split_length length exceeds the length of string, the entire string is returned as the first (and only) array element. Syntax: array str_split ( string string [, int split_length] );Example :< ?php$strW3 = "Hello w3answers";$arrW3 = str_split($strW3 );$arrW3 = str_split($strW3 , 3);print_r($arrW3);print_r($arrW3);?>
