Embeder

Embeder uses the phpembed SAPI from PHP inorder to embed a version of PHP into itself. From there is uses win32std to access a PHP file and run it from it's internal res.

Limitations

Currently, there is one major limitation: It does not embed PHP completely, rather it ouputs PHP into a DLL, as of now called php7ts.dll This is the same for extensions, shared ones must be loaded via php.ini

Compiliation Requirements

See appveyor...

Current release

Extensions are compiled statically - See release notes for extensions

Additional extensions included:

  • Winbinder
  • Win32ps

Additional library's

  • FreeImage - Use with Winbinder or FFI

Bootstrap override and exit codes

By default, the embedded bootstrap include remains:

include 'res:///PHP/LIB';

You can override the include target through PHP INI with:

embeder.bootstrap=/path/to/bootstrap.php

embeder.bootstrap defaults to an empty value, so if it is unset/empty the embedder falls back to res:///PHP/LIB.

Exit-code behavior is deterministic:

  • If zend_eval_string(...) fails, the process exits with failure (EXIT_FAILURE).
  • If the eval result is an integer/long, that value is returned (clamped to the platform int range).
  • If the eval result is not an integer, it is converted safely to a long and then clamped to int before returning.
  • If no usable eval value is available, the process exits with failure (EXIT_FAILURE).
