 The shortest way to benchmark your code is to use the benchmark method:
 ```php
-print Chrono::benchmark(function () {
+echo Chrono::benchmark(function () {
     sleep(1);
-}); // Time: 1 second (1002 ms)
+});
+```
+
+Output:
+```
+Time: 1 second (1002 ms)
 ```
 
 By default, it invokes the 'meter' method which pretty-prints the output. Optionally, you can pass a second parameter to invoke any available formatting methods (ms, seconds, minutes):
 ```php
-print Chrono::benchmark(function () {
+echo Chrono::benchmark(function () {
     sleep(1);
-}, 'ms'); // 1002
+}, 'ms');
+```
+Output:
+```
+1002
 ```
