[Bug] PHP For Loop output is not working properly.

**Describe the bug**
When I am running this PHP For loop it's showing random output sometimes it shows half of the total output and sometimes it showing nothing. Another problem is, I set clean previous output when new code runs but it's not working while using this For loop.

1. Run PHP For loop
2. Clear previous output

**Actual behavior**
