Description:
------------
PHP 7.0.1 Thread Safe on Windows Throws String convertion error.

This happened when I tried to access database object 

Test script:

$obj = $db->results();

$arr = ['tbfield1', 'tbfield2', 'tbfield3'];

// Get column tbfield1
$getColumnArray = $obj->$arr[0]; // Then PHP 7.0.1 throws error String convertion error



Expected result:
----------------
Return array of column from PHP stdClass

Actual result:
--------------
ErrorException: Array to string conversion

Expressions like $obj->$arr[0] are evaluated differently in PHP 7 than before.

Use $obj->{$arr[0]} instead.
