How to convert line breaks into codes?

Question

How can I convert line breaks into codes? For instance,

$array = array(
    'title' => 'abc',
    'content'  => 'a paragraph

    line break

    line break

    '
);

I want to convert $array['content'] to

a paragraph\r\n\t\r\n\tline break\r\n\t\r\n\tline break\r\n\t\r\n\t

Answer 1

You can also try:

echo addcslashes($array['content'],"\n\r\t");

(If you intend to keep the line feeds as your original example).

Answer 2

Something along these lines?

$array['content'] = str_replace(array("\n", "\t"), array('\r\n', '\t'), $array['content']);
