Question

Answer 1

+6 A:

$Output = preg_replace('/'.preg_quote('<br>&'.'nbsp;').'$/i', '', $String);

Where $String is the input and $Output is the result.

Why the string concatenation inside preg_quote, if I may ask?

SO doesn't like the entity (replaces with a real non-breaking-space ;)

sirlancelot 2009-04-13 15:58:27

er... why not replace it with ?

Answer 2

+1 A:

Slightly faster, if what you are trimming is constant:

$haystack = "blah blah blah <br>&"."nbsp;";
$needle = "<br>&"."nbsp;";
echo substr($haystack, 0, strrpos($haystack, $needle));

An interesting solution, but it will likely break if the needle also appears somewhere in the string, not necessarily at the end.

sirlancelot 2009-04-13 21:48:38

That is true. I've updated the solution to use strrpos instead of strpos, which searches from the end of the string instead.

php: trim <br> from the end of a string?
