A long string of text can often break the formatting of a page - particularly if text is rendered in a narrow table. The solution: Implement a PHP function that will wrap a string over multiple lines.
Line-wrapping is commonly used by utilizing a hyphen (a dash, actually) to divide words at the nearest breakpoint between syllables, indicating that the letters form a word fragment - not a word. In the following case, the breakpoint is defined by the container or table it is in.

In this case, the only long 'word' was a URL, and it was split (hyphenated) over multiple lines within a table cell.
