Solder your Rust into PHP

This library tries to help you improve your PHP application using extensions written in Rust.

The idea is to be able to write code purely in rust, compile it using cargo and load the library direct into PHP.

Note that this is the first version of this crate and a lot of things will change. Also, I can't stress enough how unstable this crate is right now. Use it with caution.

Example:

```rust extern crate libc; extern crate solder;

use libc::; use solder::; use solder::zend::; use solder::info::;

[no_mangle]

pub extern fn phpmoduleinfo() { printtablestart(); printtablerow("A demo PHP extension written in Rust", "enabled"); printtableend(); }

[no_mangle]

pub extern fn getmodule() -> *mut zend::Module { let mut entry = Box::new(zend::Module::new( cstr!("helloworld"), cstr!("0.1.0-dev"), ));

entry.set_info_func(php_module_info);

let args = Box::new([ArgInfo::new(c_str!("name"), 0, 0, 0)]);
let funcs = Box::new([Function::new_with_args(c_str!("hello_world"), hello_world, args), Function::end(), ]);
entry.set_functions(funcs);

Box::into_raw(entry)

}

[no_mangle]

pub extern fn helloworld(data: &ExecuteData, retval: &mut Zval) { let mut namezval = Zval::newasnull(); phpparseparameters!(&mut namezval); let name = String::tryfrom(namezval).ok().unwrap(); let hello = format!("Hello {}", name); php_return!(retval, hello); } ```

To compile it, we need to add to our .cargo/config: [build] rustflags = ["-C", "link-arg=-Wl,-undefined,dynamic_lookup"]

Than, you compile the extension using cargo build and load it copying it to your PHP modules dir and modifying you php.ini.

For now, this crate only works with PHP7. During the build, it tries to get the PHP API VERSION and PHP EXTENSION BUILD from the installed PHP. But, you can compile for other versions by manually setting the envs PHPAPIVERSION and PHPEXTENSIONBUILD.
