Crate php_ast 

AST type definitions and visitor infrastructure for the PHP parser.

This crate provides:

• The complete set of AST node types (ast module) — statements, expressions, declarations, type hints, operators, and all other syntactic constructs for PHP 8.0–8.5.
• A Span type for tracking byte-offset ranges back to the source text.
• A visitor module with the visitor::Visitor and visitor::ScopeVisitor traits for depth-first AST traversal, plus free walk_* functions that drive the default recursion.

Quick start

Parse a PHP file with php-rs-parser and then walk the AST with a custom visitor:

use php_ast::visitor::{Visitor, walk_expr};
use php_ast::ast::{Expr, ExprKind};
use std::ops::ControlFlow;

struct FunctionCallCounter(usize);

impl<'arena, 'src> Visitor<'arena, 'src> for FunctionCallCounter {
    fn visit_expr(&mut self, expr: &Expr<'arena, 'src>) -> ControlFlow<()> {
        if matches!(expr.kind, ExprKind::FunctionCall(_)) {
            self.0 += 1;
        }
        walk_expr(self, expr)
    }
}

Re-exports

pub use span::Span;

pub use ast::*;
