Bug description:call a class function whose name is in array

Description:
------------
Calling a class function whose name is in an array, works in php 7 no
longer as in PHP 5.6.x



Test script:
---------------
<?php

class foo {

  private $functions = array(
      array('funcName' => 'FUNC1'),
      array('funcName' => 'FUNC2'),
      array('funcName' => 'FUNC3')
  );

  function FUNC1() {
    echo 'FUNC1', PHP_EOL, PHP_EOL;
  }

  function FUNC2() {
    echo 'FUNC2', PHP_EOL, PHP_EOL;
  }

  function FUNC3() {
    echo 'FUNC3', PHP_EOL, PHP_EOL;
  }

  /** this worked only up to PHP 5.6.16 */
  public function callAllFunctions() {
    foreach ($this->functions as $values) {
      echo 'call ', $values['funcName'], PHP_EOL;
      $this->$values['funcName']();
    }
  }

  /** this code must be used in PHP 7.x
    public function callAllFunctions() {
      foreach ($this->functions as $values) {
        echo 'call ', $values['funcName'], PHP_EOL;
        $fncName = $values['funcName'];
        $this->$fncName();
      }
    }
   */
}

$test = new foo();
$test->callAllFunctions();


Expected result:
----------------
expected result as in PHP 5.6.16:

call FUNC1 
FUNC1 

call FUNC2 
FUNC2 

call FUNC3 
FUNC3


Actual result:
--------------
result in PHP 7.0.1

call FUNC1
