Bad error line and file for invalid "-d" arguments

[kkmuffme]

Description

The following code:

php -d 'foo=bar=asd' -r "echo 'hello' . PHP_EOL;"

Resulted in this output:

PHP:  syntax error, unexpected '=' in Unknown on line 6
hello

But I expected this output instead:

PHP:  syntax error, unexpected '=' in -d option on line 0
hello

Not sure where it gets that line 6 from, and the "Unknown" could also be improved

PHP Version

8.5

Operating System

No response

I agree this is not ideal.
I can explain where the number 6 comes from though. php_cli.c defines HARDCODED_INI that are parsed first, and then all the -d are parsed. HARDCODED_INI has 5 lines; so your custom -d define is the 6th.
