PHP str_split() 函数 实例 把字符串 “Hello” 分割到数组中： <?php print_r(str_split("Hello")); ?...定义和用法 str_split()函数把字符串分割到数组中。 语法 str_split( _string,length_ ) 实例 1 使用 length 参数： <?...php print_r(str_split("Hello",3)); ?
str_split str_split — 将字符串转换为数组 如果指定了可选的 split_length 参数，返回数组中的每个元素均为一个长度为 split_length 的字符块。...两个函数内部实现异同 str_split 使用 add_next_index_stringl 截取字符添加到数组中。explode使用zend_hash_next_index_insert_new。
