## Update from phpgeo 2.x to phpgeo 3.x
|
||
|
|
|
||
|
|
### Requirements
|
||
|
|
|
||
|
|
- _phpgeo_ 3.x requires at least PHP 7.2
|
||
|
|
|
||
|
|
### Update phpgeo
|
||
|
|
|
||
|
|
- run `composer require mjaschen/phpgeo:^3.0` or
|
||
|
|
- update the version constraint in your `composer.json` to `^3.0` and run `composer update`
|

|
|
||
|
|
### Update Your Code
|
||
|
|
|
||
|
|
The result of `Ellipsoid::getName()` for the built-in *WGS-84* ellipsoid returned `World␣Geodetic␣System␣␣1984` in *phpgeo* 2.x (two space characters before `1984`). Starting with *phpgeo* 3.0, the result is `World␣Geodetic␣System␣1984` (single space character before `1984`). Please verify that your code is still working if you're using that result.
|
||
|
|
|
||
|
|
Starting with *phpgeo* 3.0 class constant visiblity modifiers are used. One class constant was changed to *private* visibility: `BearingSpherical::EARTH_RADIUS`. Please verify that your code isn't using that class constant.
|
||
|
|
|
||
|
|
No further breaking changes were introduced with *phpgeo* 3.0.
