如何擴展pycharm支持php？

php中使用call:

<?php

// An example callback function

function my_callback_function() {

echo 'hello world!';

}

// An example callback method

class MyClass {

static function myCallbackMethod() {

echo 'Hello World!';

}

}

// Type 1: Simple callback

call_user_func('my_callback_function');

// Type 2: Static class method call

call_user_func(array('MyClass', 'myCallbackMethod'));

// Type 3: Object method call

$obj = new MyClass();

call_user_func(array($obj, 'myCallbackMethod'));

// Type 4: Static class method call (As of PHP 5.2.3)

call_user_func('MyClass::myCallbackMethod');

// Type 5: Relative static class method call (As of PHP 5.3.0)

class A {

public static function who() {

echo "A\n";

}

}

class B extends A {

public static function who() {

echo "B\n";

}

}

call_user_func(array('B', 'parent::who')); // A

?>
