### Build & Install

go get:

```
go get github.com/kitech/php-go
cd $GOPATH/src/github.com/kitech/php-go
# adjust PHPCFG path if needed
PHPCFG=`which php-config` make
```

manual:

    mkdir -p $GOPATH/src/github.com/kitech
    git clone https://github.com/kitech/php-go.git $GOPATH/src/github.com/kitech/php-go
    cd $GOPATH/src/github.com/kitech/php-go
    make
    ls -lh php-go/hello.so
    php56 -d extension=./hello.so examples/hello.php


### Examples

```go
// package main is required
package main

import "git.nspix.com/golang/php/extension"

func foo_in_go() {
}

type Bar struct{}
func NewBar() *Bar{
    return &Bar{}
}

func init() {
	extension.InitExtension("mymod", "1.0")
	extension.AddFunc("foo_in_php", foo_in_go)
	extension.AddClass("bar_in_php", NewBar)
}

// should not run this function
// required for go build though.
func main() { panic("wtf") }
```

### Limitations

* Deadlock in pcntl_fork'ed subprocess when call extension functions. #47
