+# Example of a Cron Job for Running a PHP Script
+
+To run a PHP command using a specific version, you need to provide the absolute path to the desired PHP version. Below is a list of the available versions:
+
+- `/usr/bin/php4.4-cli`
+- `/usr/bin/php5.2-cli`
+- `/usr/bin/php5.4-cli`
+- `/usr/bin/php5.5-cli`
+- `/usr/bin/php5.6-cli`
+- `/usr/bin/php7.0-cli`
+- `/usr/bin/php7.1-cli`
+- `/usr/bin/php7.2-cli`
+- `/usr/bin/php7.3-cli`
+- `/usr/bin/php7.4-cli`
+- `/usr/bin/php8.0-cli`
+- `/usr/bin/php8.1-cli`
+- `/usr/bin/php8.2-cli`
+- `/usr/bin/php8.3-cli`
+- `/usr/bin/php8.4-cli`
+
+Below is an example configuration of a cron job that uses the `/usr/bin/php8.3-cli` version to execute a script:
+
+```yaml
+runtime:
+  cron-jobs:
+    - command: /usr/bin/php8.3-cli $HOME/htdocs/"path/to/your/script"
+      schedule: "* * * * *" # runs every minute
+```
+With this configuration, the cron job will run every minute using the specified PHP version to execute the script located at $HOME/htdocs/"path/to/your/script".
