Features:

• Fully support PHP5 and PHP7 syntax
• Abstract syntax tree representation
• Traversing AST
• Namespace resolver

Install

Example

package main

import (
	"bytes"

	"github.com/z7zmey/php-parser/php7"
	"github.com/z7zmey/php-parser/visitor"
)

func main() {
	src := bytes.NewBufferString(`<? echo "Hello world";`)
	nodes, comments, positions := php7.Parse(src, "example.php")

	visitor := visitor.Dumper{
		Indent:    "",
		Comments:  comments,
		Positions: positions,
	}
	nodes.Walk(visitor)
}

CLI dumper

Namespace resolver

Namespace resolver is a visitor that traverses nodes and resolves nodes fully qualified name. It does not change AST but collects resolved names into map[node.Node]string

• For Class, Interface, Trait, Function, ConstList nodes collects name with current namespace.
• For Name, Relative, FullyQualified nodes resolves use aliases and collects a fully qualified name.
