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.
If your problem can't be managed by CSS, consider the following.
In this case, the only long 'word' was a URL, and it was split (hyphenated) over multiple lines within a table cell.
Usage:
Depending on your needs, the PHP wordwrap function may be all that you require. If you need to break a URL, consider truncating them.
