production env or define your target platform in the config. Example: `{"php":
"7.0.3", "ext-something": "4.0.3"}`.
This will make sure that no package requiring more than PHP 7.0.3 can be installed
regardless of the actual PHP version you run locally. However it also means
the dependencies are not checked correctly anymore, if you run PHP 5.6 it will
install fine as it assumes 7.0.3, but then it will fail at runtime.
Therefore if you use this it is recommended, and safer, to also run the
[`check-platform-reqs`](03-cli.md#check-platform-reqs) command as part of your
deployment strategy.
If a dependency requires some extension that you do not have installed locally
you may ignore it instead by passing `--ignore-platform-req=ext-foo` to `update`,
`install` or `require`. In the long run though you should install required
extensions as if you ignore one now and a new package you add a month later also
requires it, you may introduce issues in production unknowingly.
