Description:
------------
A simple code:
<?php
$con = mysqli_init();
mysqli_options( $con, MYSQLI_OPT_CONNECT_TIMEOUT, 2);
var_dump($con);

or OOP style

<?php
$con = mysqli_init();
$con->options(MYSQLI_OPT_CONNECT_TIMEOUT, 2);
var_dump($con);


Generates multiple Warnings - Warning: var_dump(): Property access is not allowed yet in [file] on line 4


I noticed this when running Xdebug with xdebug.collect_params=3 (https://bugs.xdebug.org/view.php?id=1714) but Derick pointed out it not to be Xdebug rather than mysqli problem.


Is this expected?

While in a production code there probably won't be a var_dump() it makes the development environment problematic and confusing.

The workaround for Xdebug is to use OOP style but var_dump() still produces Warnings.


Test script:
---------------
php -r '$con=mysqli_init();mysqli_options($con,MYSQLI_OPT_CONNECT_TIMEOUT,2);var_dump($con);'

Expected result:
----------------
No warning.

Actual result:
--------------
