ts2php

under development

typescript 转 php

usage

compiler

import {compile} from 'ts2php';

const result = compile(filePath, options);

runtime

部分功能依赖一个 php 的类库，需要在 php 工程中引入

require_once("/path/to/ts2php/dist/runtime/Ts2Php_Helper.php");

Features

Javascript Syntax

for/for of/for in

let b = 1;
for (let i = 0; i < 10; i++) {
    b += 10;
}

const a = [1, 2, 3];
for (const iterator of a) {
    console.log(iterator);
}

const d = {a: 1, b: 2};
for (const iterator in d) {
    console.log(iterator);
}

output

$b = 1;
for ($i = 0; $i < 10; $i++) {
    $b += 10;
}
$a = array(1, 2, 3);
foreach ($a as $iterator) {
    var_dump($iterator);
}
$d = array( "a" => 1, "b" => 2 );
foreach ($d as $iterator) {
    var_dump($iterator);
}

if/else if/else

const a = true;

if (!a) {
    const b = 456;
    const c = 123;
}
else {
    const d = 789;
}

output

$a = true;
if (!$a) {
    $b = 456;
    $c = 123;
}
else {
    $d = 789;
}

swtich

let b = 2;
let c = 1;
switch (b) {
    case 1:
        c = 2;
        break;
    case 2:
        c = 3;
        break;
    default:
        c = 4;
}

output

$b = 2;
$c = 1;
switch ($b) {
    case 1:
        $c = 2;
        break;
    case 2:
        $c = 3;
        break;
    default:
        $c = 4;
}

while/do while

const a = true;
let b;
while(!a) {
    b = 2;
}
do {
    b++;
} while(!a);

output

$a = true;
$b;
while (!$a) {
    $b = 2;
}
do {
    $b++;
} while (!$a);

Class/

import {Base} from '../some-utils';

class Article extends Base {

    public title: string;
    id: number;

    private _x: number;

    static published = [];

    constructor(options: {title: string}) {
        super(options);
        this.title = options.title;
        this.publish(1);
    }

    private publish(id) {
        Article.published.push(id);
        super.dispose();
    }
}

output

require_once("../some-utils");
use \Base;
class Article extends Base {
    public $title;
    $id;
    private $_x;
    static $published = array();
    __construct($options) {
        parent::__construct($options);
        $this->title = $options["title"];
        $this->publish(1);
    }
    private publish($id) {
        array_push(Article::$published, $id);
        parent::dispose();
    }
}

typeof

由于 php 中没有 undefined 关键字，故不支持返回 undefined

const d = typeof c === 'string';

output

$d = \Ts2Php_Helper::typeof($c) === "string";

delete

const e = {a: 1, b: 2};
delete e.a;

output

$e = array( "a" => 1, "b" => 2 );
unset($e["a"]);

es2015 object destructuring

const tplData: {a: number, difftime?: number, c?: 1} = {a: 1};

const {
    difftime = 8,
    a,
    c: y = 1
} = tplData;

const c = tplData.a;

output

$tplData = array( "a" => 1 );
$difftime = isset($tplData["difftime"]) ? $tplData["difftime"] : 8;
$a = $tplData["a"];
$y = isset($tplData["c"]) ? $tplData["c"] : 1;
$c = $tplData["a"];

es2015 template string

const b = '123';
const c = `0${b}45'6'"789"`;

output

$b = "123";
$c = "0" . $b . "45'6'\"789\"";

es2015 object computed property

let a = 'aaa';
let b = 'bbb';
let c = {
    [a + b]: 123,
    [b]: 456
};

output

$a = "aaa";
$b = "bbb";
$c = array(
    ($a . $b) => 123,
    ($b) => 456
);

es2015 object shorthand property

let b = 2;
let c = 1;
const a = {
    b,
    c
};

output

$b = 2;
$c = 1;
$a = array(
    "b" => $b,
    "c" => $c
);

es2015 object method

const a = {
    b() {
        return "111";
    }
};

output

$a = array(
    "b" => function () {
        return "111";
    }
);

enum

enum aaa {a = 1, b, c}
enum bbb {a, b, c}
enum ccc {
    a = 'a',
    b = 'b',
    c = 'c'
}

const str = '123';
enum ddd {
    a = str.length,
    b = str.length + 1
}

$aaa = array( "a" => 1, "b" => 2, "c" => 3 );
$bbb = array( "a" => 0, "b" => 1, "c" => 2 );
$ccc = array( "a" => "a", "b" => "b", "c" => "c" );
$str = "123";
$ddd = array( "a" => strlen($str), "b" => strlen($str) + 1 );
