Browsers ignore extraneous white-space characters, and also new lines, carriage returns and tabs, converting them all to a single space character. If you view the source in your browser, you'll see the newlines, but in regular display, your text is treated as HTML. There is a function in PHP called nl2br, which accepts a string and returns the same one with all the newlines replaced with <br> automatically, which might be easier to use if your content is in a string. Otherwise, the only way to get new lines on your actual page is to either manually use <br> tags, put the text inside a <pre> block, or use CSS to preserve the white-space.
