Php Doc for complete

define class memeber type:

public $v1; =>

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

if you won't define public $v1 you can define it in a 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 has no defined return value then you need to define it)

$value=ff(); =>

/** @var  Testa $value */
$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 member
        $this->v1=$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

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/

Configue PHP file Search for Large Project

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

{
  "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 example:

├── 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

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

You can also add the standard php library with phpstorm stubs.

Assuming you cloned this repo into /usr/local/src/phpstorm-stubs you base configuration will be:

{
  "filter": {
    "php-file-ext-list": [
      "php"
    ],
    "php-path-list": [
        "/usr/local/src/phpstorm-stubs"
    ],
    "php-path-list-without-subdir": []
  }
}

Rebuild Tags

if source is changed, re run this command to update tags: ac-php-remake-tags

if php file cannot pass from phpctags.

you can find all errors in the Messages buffer. Fix it and get to the next error

like this:

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

you need to fix an error in testa.php 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

FQA

To approach a problem　

If you want to tackle down a problem, you should

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

and retest
