[bug #62158] PHP indented heredoc ending marker are not handled correctly

[Cédric Anne]

Follow-up Comment #1, bug #62158 (project gettext):

As far as I understand the code, maybe the fix could be simple as proposed in
following diff.
Anyway, I do not have any skills in C development and I just spent 1 hours
trying to compile the lib without success, so any help would be appreciated.

```diff gettext-tools/src/x-php.c
