go-php7

Original library is at: https://github.com/deuill/go-php

中文文档：https://segmentfault.com/a/1190000007619087

This fork is for:

• Support PHP7 only, so that we can embrace the value semantics of zval
• Fix memory leaks by using zval instead of engine_value
• Use golang http request as PHP input
• Use golang http response writer as PHP output

PHP bindings for Go

This package implements support for executing PHP scripts, exporting Go variables for use in PHP contexts, attaching Go method receivers as PHP classes and returning PHP variables for use in Go contexts.

Only PHP 7.x series is supported.

Usage

Basic

Executing a script is very simple:

package main

import (
    php "github.com/deuill/go-php"
    "os"
)

func main() {
    engine, _ := php.New()

	context := &Context{Output: os.Stdout}
    engine.RequestStartup(context)
    defer engine.RequestShutdown(context)

    context.Exec("index.php")
}

The above will execute script file index.php located in the current folder and will write any output to the io.Writer assigned to Context.Output (in this case, the standard output).

Binding and returning variables

The following example demonstrates binding a Go variable to the running PHP context, and returning a PHP variable for use in Go:

package main

import (
    "fmt"
    php "github.com/deuill/go-php"
)

func main() {
    engine, _ := php.New()
	context := &Context{}
    engine.RequestStartup(context)
    defer engine.RequestShutdown(context)

    var str string = "Hello"
    context.Bind("var", str)

    val, _ := context.Eval("return $var.' World';")
    fmt.Printf("%s", val.Interface())
    // Prints 'Hello World' back to the user.
}

A string value "Hello" is attached using Context.Bind under a name var (available in PHP as $var). A script is executed inline using Context.Eval, combinding the attached value with a PHP string and returning it to the user.

Finally, the value is returned as an interface{} using Value.Interface() (one could also use Value.String(), though the both are equivalent in this case).
