 For many simple, single file projects, you may find it inconvenient to write a complete `Dockerfile`. In such cases, you can run a PHP script by using the PHP Docker image directly:
 
 ```console
-$ docker run -it --rm --name my-running-script -v "$PWD":/usr/src/myapp -w /usr/src/myapp php:7.0-cli php your-script.php
+$ docker run -it --rm --name my-running-script -v "$PWD":/usr/src/myapp -w /usr/src/myapp php:7.2-cli php your-script.php

 In order to keep the images smaller, PHP's source is kept in a compressed tar file. To facilitate linking of PHP's source with any extension, we also provide the helper script `docker-php-source` to easily extract the tar or delete the extracted source. Note: if you do use `docker-php-source` to extract the source, be sure to delete it in the same layer of the docker image.
