`run-tests.php` does not escape path when building cmd

[mvorisek]

Description

https://github.com/php/php-src/blob/php-8.2.2/run-tests.php#L2397

the $php variable is set like: https://github.com/php/php-src/blob/php-8.2.2/run-tests.php#L518

and when it is used to build a full cmd string, it must be escaped, currently when the path contains spaces, the testing fails, especially on Windows, where the path is very often in format like: C:\Program Files\PHP\php.exe

PHP Version

any

Operating System

any

Seems like we can use escapeshellarg to solve this issue I think. But we have to be careful about these lines tho:

php-src/run-tests.php

Line 1873 in b20c0e9

$php = $php_cgi . ' -C ';

&

php-src/run-tests.php

Line 1884 in b20c0e9

$php = $phpdbg . ' -qIb';

. So we only must do it on the paths, and not blindly on the $php variable.

I tried this, and it mostly works. But I ran into the following issue:
Some tests (for example sapi/cli/tests/021.phpt) use a hashbang line to invoke PHP from the CLI. The problem here is that it is not possible to escape a path in the hashbang line, so those tests will fail. The only workaround I found is to use a symlink and then override the TEST_PHP_EXECUTABLE environment variable (& friends) in order to use the symlink. But I'm not so sure if the maintainers will like this solution... Another idea might be to simply skip those problematic tests.

isn't shebang ignored when a script is run like php xxx.php?

Yes, but I'm pretty sure that test does want to test how the hashbang interacts with PHP.

based on conda/conda#186 we can probably skip the test if TEST_PHP_EXECUTABLE (in https://github.com/php/php-src/blob/master/sapi/cli/tests/021.phpt#L17) contain space

Yeah I was thinking that as well, sounds reasonable. I'll try that shortly (currently working on another issue report).
