Description:
------------
Using dots in queries, e.g. "/index.php?this.is.a.test", which returns a white page with no error, even with 'error_reporting(E_ALL)'. However using any other symbol, such as a colon, returns the correct result.

Reproduce code:
---------------
<?php
    if(isset($_GET['this.is.a.test'])) {
        echo('It works!'); exit();
    }
    if(isset($_GET['this;is;a;test'])) {
        echo('It works!'); exit();
    }
    if(isset($_GET['this;is;a;test'])) {
        echo('It works!'); exit();
    }
?>

Expected result:
----------------
It works!

Actual result:
--------------
/index.php?this.is.a.test = <white page, no error>
/index.php?this;is;a;test = 'It works!'
/index.php?this:is:a:test = 'It works!'

Reproduce code should actually read:

<?php
    if(isset($_GET['this.is.a.test'])) {
        echo('It works!'); exit();
    }
    if(isset($_GET['this;is;a;test'])) {
        echo('It works!'); exit();
    }
    if(isset($_GET['this:is:a:test'])) {
        echo('It works!'); exit();
    }
?>

PHP replaces "." with "_" in variables names.

Try isset($_GET['this_is_a_test'])  ;)
