Bug #77561 [Opn]: PHAR bootstrap script with shebang and strict types does not work

Edit report at https://bugs.php.net/bug.php?id=77561&edit=1 ID: 77561 Updated by: nikic@php.net Reported by: sebastian@php.net Summary: PHAR bootstrap script with shebang and strict types does not work Status: Open Type: Bug Package: PHAR related Operating System: Irrelevant PHP Version: 7.3.1 Block user comment: N Private report: N New Comment: I just looked into this a bit. Shebang lines are currently handled by the SAPI layer, by stripping it off before it even reaches the lexer. The CLI SAPI always does this, while the CGI SAPI has a default-enabled ini option for it (cgi.check_shebang_line), that I learned about today. Other SAPIs don't have this option. I think we'll want to move the shebang stripping into the lexer, but I'm not sure if we can get away with unconditionally enabling it. Previous Comments: ------------------------------------------------------------------------ [2019-02-04 00:20:59] spam2 at rhsoft dot net but for cli scripts exists an inconsistent hack für shebangs and the way it works makes it as example imposible write a strict-typed script which works with different SAPI's ------------------------------------------------------------------------ [2019-02-04 00:02:41] cmb@php.net > the topic is about <?php declare(strict_types=1); and you come up with a simple missing the > point? My point is that PHP sees the whole file as a single script, and that everything outside of <?php ?> is simply “rewritten” to be echoed. E.g. #!/usr/bin/env php <?php declare(strict_types=1); is compiled the same as <?php echo "#!/usr/bin/env php\n"; declare(strict_types=1); So, declare is *not* the “very first statement in the script”. ------------------------------------------------------------------------ [2019-02-03 19:24:04] phpbugs at olemartin dot org I agree with @cmb that the example with arbitrary content before the start tag should produce the error. However, it's quite a gotcha that a shebang is stripped in some cases (when executed by the cli) but not others (when included). Same should go with a BOM (and other magic numbers?). Since there are partial support for shebangs, that support should be made consistent. ------------------------------------------------------------------------ [2019-02-03 18:34:55] spam2 at rhsoft dot net @cmb seriously? the topic is about <?php declare(strict_types=1); and you come up with a simple missing the point? [harry@srv-rhsoft:/downloads]$ cat test.php foo <?php declare(strict_types=1); echo 'bar'; [harry@srv-rhsoft:/downloads]$ php test.php Fatal error: strict_types declaration must be the very first statement in the script in /mnt/data/downloads/test.php on line 2 [harry@srv-rhsoft:/downloads]$ ------------------------------------------------------------------------ [2019-02-03 18:30:09] cmb@php.net > the first php statement is after <?php See <https://3v4l.org/m0YBG/vld#output>. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
