#### Try it online: [demo](https://php-parser.com)
|
|
|
|
## Features:
|
|
- Fully support PHP5 and PHP7 syntax
|
|
- Abstract syntax tree representation
|
|
- Traversing AST
|
|
- Namespace resolver
|
|
|
|
## Install
|
|
|
|
```
|
|
go get github.com/z7zmey/php-parser
|
|
```
|
|
|
|
## Example
|
|
```Golang
|
|
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 resolves `use` aliases and collects a fully qualified name.
