base_convert — Convert a number between arbitrary bases
$number
, int $frombase
, int $tobase
) : string
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,
with a meaning 10, b meaning 11 and z meaning 35.
The case of the letters doesn't matter, i.e.
number is interpreted case-insensitively.
base_convert() may lose precision on large numbers due to properties related to the internal "double" or "float" type used. Please see the Floating point numbers section in the manual for more specific information and limitations.
number

frombase
