PlaywrightPHP

Read the console

Listen to page console messages by type and text.

This example registers a console handler, loads a page that emits log, warn, and error, then triggers another message with evaluate().

Use it to learn the order: register the handler first, then navigate or run the code that emits console messages.

Run it

bash
php content/examples/console-messages.php

Expected output:

text
[LOG] Hello from the page console
[WARNING] Heads up! This is a warning message.
[ERROR] Something went wrong.
[INFO] Additional info message from evaluate()

Line numbers may appear depending on browser metadata.

What it demonstrates

  • Console messages are runtime events from the page.
  • The handler receives message type, text, and location.
  • evaluate() can trigger browser-side console output.
  • A short delay gives asynchronous console delivery time to flush in this standalone script.
