use M-x: company-complete for complete

define class memeber type :

public $v1; =>

/**
 * @var classtype
 */
public $v1;

if you won't define public $v1 you can define in class comment ,like this =>

/**
  * @property  \Test\Testa  $v1
  * @method  int add($a,$b) 
  * @use  \Test\TestC
 */
class Testb  extends Ta { 
...
}

define class function return type:

public function get_v1() =>

/**
 * @return classtype 
 */
public function get_v1()

or define use php7 :

public function get_v1() :classtype  {

}

or define in doc:

/**
  * @method  classtype get_v1()
 */
class Testb  extends Ta { 
...
}

define variable: (**if function or member no define reutrn value you need define it **)

$value=ff(); =>

/** @var $value  Testa */
$value=ff();

like this

/**
   class define ..
   @property  \Test\Testa  $v8
 */
class Testa {

    /**
     * @var int; 
     */
	const CON=1;

    
    /**
     * @var Testb; 
     */
	public  $v1;
    /**
     * @var \Test\TestC; 
     */
	public  $v2;
    public function set_v1($v){

        //for complete system function 
        $v=trim($v);

        $c=new Testb();
        //can complete
        $c->get_v2();

        //for complete memeber 
        $this->v1=$v;


        //for complete function  return type  
        $this-> get_v2()->testC();

        //for complete field from comment
        $this->v8->testA();

        //for complete system class 
        $q=new SplQueue ();
        $q->push(11);

       //jump for class function point
        $f=array($this->v8, "test_A" );
        $f();

    }

    /**
     * 
     * @return  \Test\TestC; 
     */
    public function get_v2(){
        $this->v2;
    }
}

tags file location dir is in ~/.ac-php/project_dir for example: ~/.ac-php/tags-home-jim-ac-php-phptest/

localhost:~/.ac-php$ tree tags-home-jim-ac-php-phptest/
tags-home-jim-ac-php-phptest/
├── cache-files.json
├── tags-data-cache2.el
├── tags-data.el
└── tags_dir_jim
    ├── a.el
    ├── dir1-sss.el
    ├── testa.el
    ├── testb.el
    └── testc.el
1 directory, 8 files

config file name is .ac-php-conf.json

when run ac-php-remake-tags will .ac-php-conf.json set default json config when it's empty

like this

{
  "use-cscope" : false,
  "filter": {
    "php-file-ext-list": [
      "php"
    ],
    "php-path-list": [
      "."
    ],
    "php-path-list-without-subdir": []
  }
}

php-file-ext-list : file extern name list;

php-path-list: find php files recursion ;

php-path-list-without-subdir: find php files no recursion no find php from subdir ;

for exmaple:

├── dir1
│   ├── 1.php
│   └── dir11
│       └── 11.php
├── dir2
│   └── 2.php
└── dir3
    ├── 3.php
    ├── dir31
    │   └── 31.php
    ├── dir32
    │   └── 32.php
    └── dir33
        └── 33.php

{
  "filter": {
    "php-file-ext-list": [
      "php"
    ],
    "php-path-list": [
      "./dir1",
      "./dir2",
      "./dir3/dir32/"
    ],
    "php-path-list-without-subdir": [
      "./dir3"
     ]
  }
}

filter result is:

├── dir1
│   ├── 1.php
│   └── dir11
│       └── 11.php
├── dir2
│   └── 2.php
└── dir3
    ├── 3.php
    ├── dir32
    │   └── 32.php

31.php 33.php will not gen tags;

for laravel example

{
  "use-cscope": false,
  "filter": {
    "php-file-ext-list": [
      "php"
    ],
    "php-path-list": [
        "./app",
        "./database",
        "./vendor/laravel/framework/src/Illuminate"
    ],
    "php-path-list-without-subdir": []
  }
}

set use-cscope: false in .ac-php-conf.json

if source is changed ,re run this commond for update tags: ac-php-remake-tags

if php file cannot pass from phpctags.

you can find any error from Messages buffer fix it and next

like this

phpctags[/home/jim/phptest/testa.php] ERROR:PHPParser: Unexpected token '}' on line 11 - 

you need fix testa.php error and re run ac-php-remake-tags

if show:

no find  file .ac-php-conf.json dir in path list :/home/jim/phptest/ 

you need create file ".ac-php-conf.json" in root of project

like this:

touch /home/jim/phptest/.ac-php-conf.json

or

touch /home/jim/.ac-php-conf.json

you find a question

exec : M-x: ac-php-remake-tags-all

and retest
