 The script, [hello.php](./hello.php), is executed on PHPHP on PHP.
 
+### PHPHP on PHPHP on PHP
+
+Edit this line as the following:
+
+```diff
+ if (defined('PHPHP')) {
+-    if (PHPHP < 2) {
++    if (PHPHP < 3) {
+         echo "Running" . str_repeat(" on PHPHP", PHPHP) . " on PHP\n";
+```
+
+Then, execute `index.php`. I recommend that you enable JIT.
+
+```bash
+php -d opcache.enable_cli=on -d opcache.jit=on -d opcache.jit_buffer_size=1G index.php
+```
+
+It will execute hello world on PHPHP on PHPHP on PHP.

+Running on PHP

+Running on PHPHP on PHPHP on PHP
+Hello, World!
