php string replace remove & add word at the end

Question

Maybe really simple, but I can't get my head around how to use str_replace to do the following on multiple phrases:

Note: It is always the last word that I want to retain (i.e. London, Birmingham & Scotland or any others).

Example Phrases

I Love London

Living near Birmingham

Playing by Scotland

To be turned into:

In London Today

In Birmingham Today

In Scotland Today

Thanks

You're probably not going to be able to use str_replace() with out a lot more code:

preg_match('/\w+$/', $string, $match);
echo $match[0];

Or as an example replace:

$result = preg_replace('/.*?(\w+)$/', 'In $1 Today', $string);

Use a regular expression and preg_replace() to do it in one step:

print preg_replace('/.* (\w+)\W*/', 'In \1 today', "I love London");

I made it a bit more robust than you anticipate, by ignoring any punctuation or spaces after the last word.

Or, to use the same regexp with a whole list of strings:

$data = array("I love London", 
    "I live in Birmingham!",
    "Living near Birmingham!",
    "Playing by Scotland..."
    );

$results = preg_replace('/.* (\w+)\W*/', 'In \1 today', $data);
foreach ($results as $string)
    print $string, "\n";

While this code may answer the question, it would be better to include some context, explain how it works, and describe when to use it. Code-only answers are not useful in the long run.
