Re: rtrim a string with MySQL"s function

You can use regular expressions in mysql to check for the right format,
but (as far as i know) you can not return any matches: SELECT * FROM
table WHERE column REGEX '[0-9]+';, which returns all records where
column has a digit in its value.

In PHP however, you can easily get the matches:
$var = preg_match('/(\d+)/', $string, $matches);
You can find the first occurring digits of your string in $matches[1].

If your $string is of this form: string = [0-9]*[a-zA-Z]*|string, so
digits and alpha characters are mixed, I guess you'll need to do
something like implode $matches[1..n] if you're using the regex above.
