A Parser for PHP written in Go inspired by [Nikic PHP Parser](https://github.com/nikic/PHP-Parser)

## Features:
- Fully support PHP7 syntax (PHP5 in future)
- Abstract syntax tree representation
- Traversing AST

## Example
```Golang
package main

import (
	"bytes"

	"github.com/z7zmey/php-parser/parser"
	"github.com/z7zmey/php-parser/visitor"
)

func main() {
	src := `<? echo "Hello world";`
	nodes, comments, positions := parser.Parse(bytes.NewBufferString(src), "example.php")

	visitor := visitor.Dumper{"  | ", comments, positions}
	nodes.Walk(visitor)
}

```
