 Prettier for PHP supports the following options. We recommend that all users set the `phpVersion` option.

+### \* `phpVersion` Configuration Notes :
+
+The default setting `auto`, attempts to auto-detect your supported php versions from a `composer.json` with in the
+current directory or any parent directory, the plugin will use a minimum supported php version from
+`{"require":{"php":"..."}}` to set the phpVersion. If not found or not able to be parsed, it will default to latest
+supported PHP version.
+
+You set the `phpVersion` to `composer` and this will only use the `composer.json` file to determine the php
+version, prettier will crash if the PHP cannot be determined.
+
+You can also set the `phpVersion` to a specific version, such as `7.4`, `8.0`, `8.1`, `8.2`, or `8.3`.
+
+**Please Note:** If the phpVersion is not set correctly for your environment, this plugin will produce code that could
+be incompatible with your PHP runtime. For example, if you are using PHP 7.4, but the plugin is set to PHP 8.3, it will
+produce code that uses features not available in PHP 7.4.
