That depends on if a space is allowed between the colons. If it isn't:

$out = preg_replace('!:([^ ]+):!', '!|$1|!', $in);

is fine. You may also want to consider using a non-greedy expression instead:

$out = preg_replace('!:(.+?):!', '!|$1|!', $in);

Here is another option:

$out = preg_replace('!:([^:]+):!', '!|$1|!', $in);

$output = preg_replace('/:([^ ]+):/', '!|$1|!', $input);

You might want to replace [^ ] with a more specific set, depending on what you are expecting to be in between the :s.

Try this:

$str = preg_replace('/:([^:]+):/', '!|\\1|!', $str);
