Writing PHP Extensions in Go

[vimrus]

I‘m trying build the extension using generator, The example in document:

Code

import (
    "C"
    "github.com/dunglas/frankenphp"
    "strings"
)

//export_php:function repeat_this(string $str, int $count, bool $reverse): string
func repeat_this(s *C.zend_string, count int64, reverse bool) unsafe.Pointer {
    str := frankenphp.GoString(unsafe.Pointer(s))

    result := strings.Repeat(str, int(count))
    if reverse {
        runes := []rune(result)
        for i, j := 0, len(runes)-1; i < j; i, j = i+1, j-1 {
            runes[i], runes[j] = runes[j], runes[i]
        }
        result = string(runes)
    }

    return frankenphp.PHPString(result, false)
}

Error Output:

Error: parse source: parsing classes: parsing file: extension.go:1:1: expected 'package', found 'import' (and 1 more errors)

Add a package declaration

package go_ext

import(
    "C"
    "github.com/dunglas/frankenphp"
    "strings"
)
...

Error 2 Output:

Error: generator error at arginfo generation: failed to generate arginfo: running gen_stub script: exit status 255

In go, the package name must match the current directory name.
