Use the word boundry:

preg_replace('/\b(?:^|\s\w{1,3})\b/', '', $sentance);

Jack's answer only matched all and of.

This expression looks for the word boundaries and will match on that.

Regular expression to select words between 1 and 3 in length:

preg_replace('/\b\w{1,3}\b\s*/', '', $sentence);

The \b is to match a word boundary, the \w denotes a "word" character. The \s* at the end makes sure that excess spaces are removed too.
