base_convert — Convert a number between arbitrary bases
Description

, int $tobase
)
Returns a string containing number
represented in base tobase. The base in
which number is given is specified in
frombase. Both
frombase and tobase
have to be between 2 and 36, inclusive. Digits in numbers with a
base higher than 10 will be represented with the letters a-z,
