string chunk_split(string $str [, int $length [, string $end]])
(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 |
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.
