+# Hello world
+Same example as 01-hello-world, but uses 
+[Standard Http Server](http://webonyx.github.io/graphql-php/executing-queries/#using-server)
+instead of manual parsing of incoming data.
+
+### Run locally
+```
+php -S localhost:8080 ./graphql.php
+```
+
+### Try query
+```
+curl http://localhost:8080 -d '{"query": "query { echo(message: \"Hello World\") }" }'
+```
+
+### Try mutation
+```
+curl http://localhost:8080 -d '{"query": "mutation { sum(x: 2, y: 2) }" }'
+```
