Newbie - is there a function similar to the sql 'like' comparison operator?
I would like to be able to compare 2 strings:
If $this ---*like or similar to*--- $that
That type of thing...
I know of this page:
http://us3.php.net/manual/sl/language.operators.comparison.php
But I don't see something 'like' or 'similar' to something else

Probably the most similar that allows some wildcards (pattern matching)
is ereg(). You have more power in that you can control what must match
and how much.
In MySQL 'a' = ' a ' is true but 'a' LIKE ' a ' is false. So you need
to use the wildcard % to match anything ' xxaxx ' LIKE '%a%' is true or
_ to match one character ' a ' LIKE '_a_' is true.
The problem with similar_text() is that it gives you a percentage of
similarity which may be misleading unless you also figure in the return
of how many chars match. For example similar_text('CAT', 'CA', &$p) $p
would be 66.6%, is that like or not?
