Run On 3v4l

Run PHP code on 3v4l.org

Execute PHP code on 3v4l.org to test actual runtime behavior across multiple PHP versions. This is critical — do NOT reason about what PHP would do, actually test it.

The code to run: $ARGUMENTS

Step 1: Research the 3v4l.org submission form

Fetch the 3v4l.org homepage and examine the HTML form to understand how to submit code:

curl -s https://3v4l.org/ | head -200

Look for:

• The form action URL and HTTP method
• Required form fields (the code textarea name, any hidden fields)
• How the response redirects to the result page

Step 2: Prepare executable PHP code

Take the PHP code and make it executable:

• If the code defines classes/functions but doesn't call them, add test calls that exercise the interesting code paths
