PHP to JavaScript convertor

See playground: Online Convertor

Suports

Namespaces, use
Class, abstract class
extends and interfaces
constants and define
Exceptions and catch
continue ,break
anonymous classes
magic constants
list()
magic methods __get __set and __call (only in ES6 see Proxy in compatibility table)
private methods and properties (only in ES6 see WeakMap in compatibility table)

Planed

include and require
class generation
yield

Limitations

Its there more differences between PHP and JS. Array in PHP is asociate, but in JS is not. For that reason you can use jsphp\JsArray wich has same funcionality as build in JS Array.

In JS you have object wich is similarly to PHP arrays, but there is diferent ordering. Also is not working with builtin php functions for manipulating with arrays. So if you need this object, wich working with foreach loop, the you can use jsphp\JsObject. This object has same funcionality as JsObject. But if you want extend it, your extended object cant have public or protected members, just use it, but not declare it.

If you need some like associated array you can also use jsphp\HashArray

You can't define class constant and static properties with same name. in JS will be override.

Not suport

trait
goto
declare(ticks)

Usage

    $parser = (new \PhpParser\ParserFactory())->create(\PhpParser\ParserFactory::PREFER_PHP7);
    $jsPrinter = new \phptojs\JsPrinter\JsPrinter();

    $phpCode = file_get_contents('path/to/phpCode');
    $stmts = $parser->parse($phpCode);
    $jsCode = $jsPrinter->jsPrint($stmts);

Use auto converter

You can create file watcher for auto generation js script from your php code when is saved.

PHPStorm

go to File/Setting/Tools/File Watchers add custom watcher and set

File type: PHP
Scope: Create new scope to your php scripts to convert
Program: chose yor location to php.exe
Arguments:
- -f
- $ProjectFileDir$/../PHP-to-Javascript/bin/phpstormWatcher.php
- $FileName$
- $ProjectFileDir$/phpJs php scripts to generate
- $ProjectFileDir$/public/js/phpjs output directory
- [-p] enable support of private properties and method. If is disabled, all private fields is converted as public
Output paths to refresh: $ProjectFileDir$/public/js/phpjs

Example

interface FooInt{
    function fooIntFunc1($a, $b = 5);
}

abstract class FooAbs implements FooInt
{
    abstract function fooAbsFunc1($a, $b);

    function fooAbsFunc2($a, $b){
        return $a + $b + 10;
    }
}

class FooParent extends FooAbs{
    public $foo = 5;

    public function __construct() {
		$this->foo=5;
	}

	function fooAbsFunc1($a, $b){
		parent::fooAbsFunc2(1,5);
        return $a + $b;
    }

    function fooIntFunc1($a, $b = 5){
        return $a + $b + 5;
    }

    public static function fooStatic(){
    	return 10;
	}
}

class FooChild extends FooParent
{
    public $foo = 6;

    function fooIntFunc1($a, $b = 5){
        return $a + $b;
    }

    function testParent(){
        assert_($this->fooIntFunc1(5, 5), 10, 'testParent 1');
        assert_(parent::fooIntFunc1(5, 5), 15, 'testParent 2');
    }
}

$fooParent = new FooParent();
$fooChild = new FooChild();

assert_($fooParent instanceof FooParent, true, 'fooParent instanceof FooParent');
assert_($fooParent instanceof FooInt, true, 'fooParent instanceof FooInt');

assert_($fooChild instanceof FooChild, true, 'fooChild instanceof FooChild');
assert_($fooChild instanceof FooParent, true, 'fooChild instanceof FooParent');
assert_($fooChild instanceof FooAbs, true, 'fooChild instanceof FooAbs');
assert_($fooChild instanceof FooInt, true, 'fooChild instanceof FooInt');

assert_(FooChild::fooStatic(),10, "FooChild::fooStatic()");

$fooChild->testParent();
