===== Syntax =====

<code php>string chunk_split(string $str [, int $length [, string $end]])</code>

//(PHP 4, PHP 5)//

^ $str | The string value to be split into chunks |
^ $length | The maximum length of each piece of string split apart from **$str**.  The default value is 76 characters. |
^ $end | The character sequence that denotes the end of each piece (and is appeneded after each chunk).  The default sequence is "\r\n" (carriage return followed by a newline). |
^ RETURNS | Returns the modified string with line breaks between each piece |

===== What it Does =====

Unlike the [[explode]] function which breaks apart a string into an array, the **chunk_split** function will reformat the string, inserting a character sequence ("\r\n" by default) after each chunk.  Also, chunks are delimitted by string length and not individual characters.

===== Example =====

<code php>
echo '<h4>chunk_split<h4>';
echo chunk_split($longtext);
