Chunk_split

(PHP3 >= 3.0.6, PHP4)

Chunk_split---&http://www.aliyun.com/zixun/aggregation/37954.html ">nbsp; Cut a string into small segments

Syntax: String chunk_split (String string [, int chunklen [, String end]]

Description:

Can be used to cut a string into small segments, such as the output of a base64_encode () to the RFC 2045 semantics. It inserts the parameter end (the default value is "\ r \ n") for each chunklen (76) character. It returns a new string, but does not change the original string.

Example:

<?php

# format $data using RFC 2045 semantics

$new _string = Chunk_split (Base64_encode ($data));

?>

This function is faster than ereg_replace ()

Note: This function is a new function in 3.0.6
