Have phpdbg report the SAPI as "cli" instead of "phpdbg"

Question

When running phpdbg on the command line, the value returned from php_sapi_name() is "phpdbg" rather than "cli", which upsets some of my code that checks to ensure the code is being ran on the CLI and not in a web service.

I would rather not change my code to suit a debugger. Is there a way to have phpdbg report the SAPI as "cli" rather than "phpdbg"?

Answer 1

When calling phpdbg you can specify the -S switch to specify any name to report as the SAPI. For example phpdbg -Scli to restore it to "cli".

The official online documentation for phpdbg is at https://phpdbg.room11.org/. However, it seems to be very out of date and does not mention the -S option. To see the current list of options, run phpdbg and use the help options command.

$ phpdbg
prompt> help options

Below are the command line options supported by phpdbg
