chunk_splitDescriptionchunk_split() adds the character(s) specified in chunk_ending every chunk_length characters. This function is useful for breaking certain types of data into separate lines of a specified length. It's often used to make base64 encoded data conform to RFC 2045. NoteThis function should not be used for breaking long lines of text into shorter lines for display purposes - use wordwrap() instead. ExampleExample 1194. Make base64 encoded text conform to RFC 2045 <?php $soliloquy = <<<RICHARDIII Now is the winter of our discontent Made glorious summer by this sun of York; And all the clouds that lour'd upon our house In the deep bosom of the ocean buried.\n\n RICHARDIII; echo "Original Text:\n", $soliloquy; echo "RFC2045 Compliant Text:\n", chunk_split(base64_encode($soliloquy)); ?> Output: Original Text: Now is the winter of our discontent Made glorious summer by this sun of York; And all the clouds that lour'd upon our house In the deep bosom of the ocean buried.
