Describe the bug I'm trying to start an Xdebug session of a local PHP script, but it fails and I have the following entry in the log file:

!ENTRY org.eclipse.php.debug.core 4 4 2023-12-06 08:58:36.720

Describe your system

This is happening for me, and it is now July 2024. My configuration is similar to the original poster:

Environment: Eclipse 2023-09 (4.32) PDT Eclipse PDT 8.2.0.2023 11292129

System

@mlocati I finally figured out how to fix this myself. I found that the transfer and output encoding values were unset in the launch parameters. You can configure these values using the PHP Debug configuration Window->Preference under PHP/Debug: image

After I set both values to UTF8 I was able to debug successfully.

FYI: I would still consider this a bug since:

  1. The DBGpSession class' getCharset() was unable to devise a workable, default character set, and,
  2. The debug session entered a sort of "hung" state
