Try it online: demo
Features:
- Fully support PHP5 and PHP7 syntax
- Abstract syntax tree representation
- Traversing AST
- Namespace resolver
Install
go get github.com/z7zmey/php-parser
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
$GOPATH/bin/php-parser /path/to/file/or/dir
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 resolvesuse
aliases and collects a fully qualified name.
